Reference 6: The Next Level of High Definition®

Almost since the inception of the brand, Audio Research has produced some of the finest components for music reproduction; this is especially true with regard to preamplifiers. In 1973, the SP3 was hailed as the best preamplifier available, and this tradition of excellence has continued ever since. The Reference Series from Audio Research was first introduced in 1995 and has been the ultimate representation of performance, musicality and power. The Reference 6 is the latest chapter of our story.

The Reference 6 is not simply a market-driven product, but rather, a solution to a need which arose after the creation of the Reference SE Series amplifiers. According to Warren Gehl, who is responsible for sonic development of all Audio Research products, the new series of Reference amplifiers offer a level of musical and dynamic capability only made apparent when using the flagship, two-chassis Reference 10 preamplifier. Both preamplifiers of the Reference Series need the ability to provide the full benefit of this new sonic landscape. Increasing the tube count to six in the analog section, and advancements in the power supply improved both macro- and microdynamics and lowered distortion. The Reference 6 also offers better bass control, relaxed purity and more dimensionality. Further improvements include a more grainless presentation, greater transparency, better speed, and more continuity across the musical spectrum. Quite simply, the Reference 6 improves upon its predecessor in every way for a more palpable and immediate musical performance.

Numerous elements – transformers, capacitors, wiring – are designs exclusive to Audio Research and the Reference 6. A completely new chassis has allowed not only a more beautiful aesthetic, but also provides more structural rigidity to assist in the dissipation of electrical and mechanical interferences. Six premium 6H30 tubes are now used in the audio circuit (increased from four tubes in the Reference 5SE) to provide an even quieter background and increased dynamic range. The tube-regulated power supply is also a new design for improved sonics. New circuit boards, circuit designs, and larger power transformer have been implemented to provide robustness and serviceability. A new volume control with finer step gradation and higher performance completes the system.

The Reference 6 will prove to be an eye-opener, both sonically and visually. The first units, available in natural anodized aluminum with acrylic cover, begin shipping in November. Experience the next level of High Definition®.

An A'gon buddy just sent me an e-mail with the same advance release announcement and pic that Mike posted above. I surmise that the Ref 6 may be a very different piece of kit than the Ref 5 SE. The ARC announcement, kindly provided by Mike, states that the Ref 6 has six (6) 6H30 audio tubes. I can only infer the circuit has been materially changed as well.

Guess we'll have to wait for reviews and user comments.

Bruce,

I think this could be a really nice preamp.

[the professor]

from the pics, it looks like it will match the GS series

[Bifwynne]

Bruce,

I bet you are right. This is not a just a "super-sooped" up Ref 3.

I just checked a pic of the Ref 10 on the ARCDB web site. Interestingly, the Ref 10 is essentially a dual mono design. But each side used only 4 audio tubes (6H30) in the gain circuit ... 2 audio tubes each side (probably 2 gain stages). I wonder what the Ref 6 will sound like with 6 tubes (6H30) in the gain stage. It might represent another gain stage (maybe 3 gain stages) ... not sure. Maybe a techie will chime in.

ARC's announcement, which Mike was kind enough to post, mentions that there are "advancements in the power supply." Can't even imagine what that could be .. more caps??? I'd like to see a pic of the innards.

Let's stay on top of this. Could be interesting.

Actually, when more information is released, I think you may be surprised. Yes ... it looks like a GS type amp on the outside. But based on reviews I have read about the GS Pre, it was pretty much a prettied-up Ref 5 SE, with a PH-8 phono pre shoved into one chassis. I am guessing the Ref 6 could be more ... much more. We'll have to wait until more information is released.

The new McIntosh C110T has 3 tubes per channel for a total of 12 tubes (phono and line stage).

Joe-I honestly have no idea. I just checked ARC's website and they are still showing the Ref 5SE and not the Ref 6. I would imagine that ARC is going to drop the Ref 5SE if the Ref 6 is supposed to be better and the price is oh so close. If the Ref 6 is truly better than the Ref 5SE, hats off to ARC for introducing a newer and better preamp at a very moderate price increase.

It uses a 6550 and a 6h30 in the power supply. The power transformer is supposed to be bigger and the Ref 6 weighs 6 lbs more than the Ref 5SE. ARC is saying the Ref 6 is a big improvement over the Ref 5SE. I will be most interested to say the least.

The Reference Series from Audio Research was introduced in 1995 and has been the ultimate representation of performance, musicality and power. Beginning with the Reference 1, the Reference 6 now continues the tradition of using the most re ned circuit designs in concert with the highest quality parts and components. Numerous elements – transformers, capacitors, wiring – are designs exclusive to Audio Research and the Reference 6. A completely new chassis has allowed not only a more beautiful aesthetic, but also provides more structural rigidity to assist in the dissipation of electrical and mechanical interferences. Six premium 6H30 tubes are now used in the audio circuit (increased from four tubes in the Reference 5SE) to provide an even quieter background and increased dynamic range.

Further improvements include a more grainless presentation, greater transparency, better speed, and more continuity across the musical spectrum. Quite simply, the Reference 6 improves upon its predecessor in every way for a more palpable and immediate musical performance.

The Reference 6 line stage preamplifier is housed in a single chassis paneled in custom-machined aluminum. The vacuum tube audio stage utilizes six 6H30 vacuum tubes (three per channel), and one 6H30 and a 6550WE provide regulation in the power supply. The large, vacuum fluorescent display on the front panel shows all functions and volume. Two rotary encoders provide input selection and volume control, and a row of ve buttons control power, mute, invert, mono and menu controls. Menu functions include: input labeling, display brightness, processor input setup and tube hour reset. Four balanced and four single-ended inputs provide system connectivity. There are two main outputs providing both balanced and single-ended, as well as a record out. RS-232, IR input, and 12V trigger allow for additional control options. The Reference 6 ships with a full-function metal remote.

I have someone who wants to buy my air tight ate 2001 preamp. I had sold my ref 5se since it didn't sound as good in my system as the air tight. If I could get the arc ref 6 at a discount I would sell my friend the air tight since any marginal difference would be made up due to convenience of one box and balanced inputs and outputs. Anyone here an ARC dealer or have connections ? Darrin

[cmalak]

Nelson (HighEndGuy) is an ARC dealer based out of the Dominican Republic I believe.

[ctop]

Not surprisingly, four ref 5se units already for sale at Audiogon since yesterday...

[Dpod4]

If I could find a ref 6 for 11.5k I would get it.

[PureVinyl]

Had a chance to hear the AR GSpre and GS150 amp paired with the Focal Sopra 2 (great looking speaker-Amazing build quality)


IMO: did not make a great combo, with the KT150's i thought it sounded a little harsh and kinda light on the dynamics.

But when paired with PASS XA100.5 mono's it sounded great!


was hoping for a better showing of the new GS series

Cheers

Perhaps the GS150 was simply not a good electrical match with the Focals. Even though the output impedance of the GS150 is "low'ish," even off the 4 ohm taps it runs between .55 and .87 ohm). Even higher off the 8 ohm taps. See Atkinson bench measurements: http://www.stereophile.com/content/audio-research-reference-150-power-amplifier-measurements#ojrKAzdOYUIGP5MC.97 (Note: the GS150, Ref 150 and Ref 150 SE have almost identical electrical specs).

By contrast, I surmise that the Pass's output impedance is more typical of a normative SS "Voltage Paradigm" amp ... that is, very, very low. A possible result could be that if the Focals have a prominent impedance peak at the mod/tweeter point, the SPL output in that FR spectrum might be a little augmented ... resulting in a sense of harshness. Even more so if the 8 ohm taps are used. All guesses of course.

Of course, I assume that all of the gear that was auditioned was well broken-in.

Thanks for your opinions. Always helpful.

I can confirm that Pass Class A with Focal is a GREAT match. Then again, I haven't found anything that isn't a great match with my Pass amps - yet.

I would love to hear the REF6 with the GS150's. I bet on SF speakers that would be magic.

I have to say, I think the GS150 is one of the greatest amps I've ever heard. One of those amps that comes along once every 10 years or so. One of those amps that is so good, even the designers can't believe how good it turned out.

ARC is really on a roll lately. Good on them. Every piece of ARC gear I've ever owned, has been world class - regardless of price.

Mike -

I agree with you. I heard the GS150 with the ARC Ref 10 and Wilson XLFs - the system sounded fantastic. While the XLFs are very efficient, the GS150 rocked! Transparent, dynamic with "cojones" on the bottom end. And, it looks terrific!

My sense is that the Ref 6 and the GS150 will be a killer combo.

Yes, the GS150 sounds great. But the GS preamplifier was not good enough to extract its full potential - I listened to the GS150 with the REF5SE and the GS preamplifier and the difference was very large. Now with the REF6 SE everything seems in place.

Do we have any picture of the inside of the REF6 SE?

[Packfill]

An early post in this thread remarked that the new Ref6 was only $1000 more than the Ref5SE.

Am I the only one who believes that audio electronics, like most other manufactured/technology goods, should be going down in price over time and not up?

[joeinid]

Welcome to the forum Packfill, thank you for joining.

[Dpod4]

I think the Ref 6 is retailing at $14k. Given that it should be noticeably improved over the 5SE, closer to the Ref 10 (my dealer told me that it should be noticeably better than the ref 40 which was a little better than the Ref 5se). Given price of ref 10 I applaud arc for not being greedy and pricing it at $18-20k.

[Ritmo]

Excellent point. Given the excitement generated by the Ref 6 announcement, I would not be surprised to see ARC raise its price around CES.

Except for cosmetics and ergonomics, is there a good reason why not to put the power supply for a tubed preamp into a separate chassis?

[cmalak]

Ref 10 is a two chassis preamp for ARC (also the Ref 10 phono) but as Mike said, they have opted to go with separate power supply chassis in their top end reference product at their premium price point because of the added cost. McIntosh, VAC, and a few others have similar product lineups with the two chassis (separating clean and dirty boxes) in their premium end preamp products.

[DaveC]

Except for cosmetics and ergonomics, is there a good reason why not to put the power supply for a tubed preamp into a separate chassis?

Cost and ergonomics is worse, and then you also have to deal with wiring between the two, which is not trivial. IMO a single larger chassis is better. It's not like the PTs and such can't be isolated within a single chassis if needed.

I did notice the AR Ref 6 has a bunch of big electrolytic caps in there, for the price I'd want a PS that uses film caps.

[BayStBroker]

I'm constantly surprised by how little detail super high-end preamplifier manufacturers provide about the volume control that they install. "A new volume control with finer step gradation and higher performance completes the system," is what ARC tells us. This sort of vague description makes a volume control seem like an afterthought. ARC is by no means unique in this regard. But the whole signal goes through the volume control and is constantly regulated by it! By contrast, Robert Koda makes a big deal of his hand-made attenuators. http://www.audioshark.org/attachment.php?attachmentid=13445&stc=1

I see specs list a 6550C tube instead of the usual 6550WE. Wonder if that is a typo.

I see specs list a 6550C tube instead of the usual 6550WE. Wonder if that is a typo.

Deafone ... ARC stopped using SED 6550 "winged C" tubes a while back. The reason is that the original Svetlana factory in St. Petersburg where the SED 6550Cs were made burned down several years ago. Another Russian tube manufacturer took over the name, but the new tubes are not the same quality. For some time, Upscale Audio wouldn't even sell old SED 6550 "winged C" tubes that were floating around the market because of quality issues. That may have changed. You'd have to call Kevin Deal at Upscale to get an update.

In the meantime, ARC moved on to Sovtek, which makes 6550 WE tubes. In fact, ARC sold me two new 6550 WE replacement tubes for my Ref 5 SE linestage and Ref CD-8 CDP.

Hope this helps.

I recently had a long audition of a system that included the ARC Ref 6. The Ref 6 sounded absolutely incredible. One of the best preamps I've ever heard (I've owned the Pass XP-30 and currently own the Soulution 520). The organic presentation, combined with the scale, dynamics, detail and nuance were amazing. In a word, wow!!!

Are you going to be able to try it in your system? that will be the true test.

[madfloyd]

Agreed. How was tonality/coloration?

What was the rest of the system that you heard it with?

[Alpinist]

[QUOTE=madfloyd;159687]Agreed. How was tonality/coloration?

Ian,

The tonality was very accurate with little coloration.

In December I heard the ARC Ref 6 in a friend's system. He had it paired with a Hegel H30 and Revel Salon 2's. I concur with Ken and had the same general impression. Hope this helps

[Alpinist]

The ARC REF 6 is a tremendous preamp. It replaced an ARC REF 5SE in a system I'm very familiar with. While the REF 5SE produced outstanding sound, replacing it with the REF 6 brought the system to an entirely different/higher level, in my opinion. More dimension, better dynamics and lower noise floor. I've not auditioned the REF 10 yet but I would bet the REF 6 gets you in the ballpark. Really amazing.

I hook mine up this weekend along with some other new gear. Just spent the week in Bend listening to my second system with a new SRA Ohio class stand under my amg v12 table.

Not yet.

[Alpinist]

The REF6 preamp absolutely kicks ass with the Aesthetix Atlas monoblocks, which utilize one 6SN7 tube per channel for all the voltage gain and all solid state for the output stage. I bet it would sound great with most solid state amps that have a high enough input impedance. I was truly impressed with the REF6.

Hegel H30 Balanced Input Impedance = 20,000 Ohms

ARC REF6 Balanced Output Impedance = 600 Ohms

20,000 / 600 = 33.3X (Should be at least 10X greater)

Should be good from an impedance perspective. I bet it will sound great too. You should give one a whirl in your system.

The rest are ARC GS150, EAR/Yoshino CD player, Wilson SashaII, All cables from Furutech Flex line, I liked to upload their pictures but can't do that because although I choose picture file but it doesn't give me option to upload it or the upload button does not response; pity!

I will get the Reference 6 on coming weekend. :yahoo1:Used and have only 100 hrs. on it. It will be first Audio Research product for me. It will be drive my Pass XA 160.5. I hoop it will be good synergy. No listening session first ( no dealer have then here) ;-/ I hope it will improve my Pass XP20 in some Tube- sweetness / more organic sound.

Does anybody knows how long will it take to break in ? According some sites 300 hrs. or 600+ hrs. :?
And have somebody data how big in uF – capacity are those gold capacitors ?

Mine getting better after around 200hour, although it was nice sounding from start but now what I feel after 200 is more transparency and dynamic range, less distortion in high volume and better separation; It seems its just beginning to show its abilities! You will love it. Don't expect overly warm sound of tube; It is really very low coloration device, monitor class/ reference class preamplifier

Many congrats! Exciting news... Mine is still burning in. I have a friend who said at 600 hours magic happens... So I'm waiting to get there myself. Hard to imagine it getting better.

It should outperform your XP-20 as for me it did so with my XP-30. Although the XP-30 is also amazing.

[Ritmo]

My experience has been that by the 400 hr point, ARC sound has stabilized and small improvements will continue until 600 hrs. Do not give up on the gear until it gets to 600 hrs. I've seen people be impatient and sell their ARC gear before it is operating at its full potential.

2 cents...

[mep]

The piece of paper that comes in the box with your ARC Ref 6 says it takes 600 hours for full break in. It sounds great fresh out of the box so it's nothing to get your panties in a bunch over.

[nc42acc]

I think the person I bought my REF5SE from didn't let it burn in long enough. I think it sounds amazing, cannot imagine the REF6 being better.

:D I loved my Ref 5SE and thought it sounded great. I just had enough faith in ARC that the Ref 6 would be better since they rarely make missteps. Completely different circuit (poor man's Ref 10?) using 6 tubes instead of 4, beefier power supply as well as the power supply was redesigned. I have no regrets.

[slowikpl]

Hi all ,

I have now 2 days the ARC Ref6 Pre. This is only my opinion so it is my kind of putting in the paper wwhat I experience and compare with. And I must say I’m very impressed by this gear. I was always in love in Tube-sound. But the Tube -effect on some gear what I had listened to was little to slow and sometimes little to sweet to be lifelike reproduction of music. The ARC is never that kind of reproduction. From beginning of listening at 160 hrs on the timetable I was seduction and first hear love. The attack of the bass what I was afraid from tube- gear is sublime. The Bas is lighting fast and very differential. At highs more details stroke me first with the kind finesse that I can remember I first time audition my Aleph -X. Many many more air and effortless reproduction of the sound. Not like correct -sound like my Aleph XP20 , it is music with everything what is music about ! The mids tones are very fine and much meat on the bones. Far better than my old XP20. The XP20 I IMHO good gear for the recording – studio like reproduction. Nothing more than good and correct reproduction. And the ARC Ref6 is IMHO the gear that you forget that you listening to gear , the main importance is the music reproduction , and Thake the journey in to music. That’s what is for me most important.
At 181hrs the first 40 minutes ware ok , but nothing special. Harsh . I Think that this had to do with the Burn-in effect. I will now listen to it 4 full day`s to go asap to the 300 – 600hrs mark. I`m so exciting what will happen. I will report further at 300 hrs mark.
If you have some question feel free to ask.

What is little less that my Plexy-glass top cover have little band from the heat above the 6550 Tube. I have now applied some aluminum tape from the inside side and cut in the venting holes in it. I hope this wil solve the issue.


Today the sound is not that amazing like yesterday . I do not understand this. Could it be that at 190HRS the unit can be that night- day different?

Up and down until the break-in period is completed. Pretty typical. I heard a Ref 3 phonostage before the break-in period was completed and I thought it sounded pretty bad. Really thin and bright in the treble. Patience is the key.

Thanks Ken. Today it sounded at 253 HRS really as you describe it. Degradation 100% So I don't listen to it before let's say 400HRS. Because it makes me nervous.

I have read somewhere that I can only pass the sound from source through the Preamplifier without turning the amplifiers on. Set the gain at 80 to quicken the burin-in period. Can someone else confirm that?

You can but half volume should be sufficient.

[mep]

I think the break-in period and the attendant changes people claim to hear are overblown. The Ref 6 sounds great fresh out of the box from the factory. If you think you shouldn't listen to it until you hit some magic number of hours on the meter because it's not going to sound very good, something is wrong between your ears and/or your system is hosed. Yes, there are subtle improvements as the hours roll by, but not the way some people portray them. Maybe I should start selling audiophile worry beads.

[slowikpl]

Hi Mep. I don't think that. The day before I know what I heard. It was great. And yesterday It was crazy. Sound was very hard , bright and without any finesse.
Today it was nothing special at all. I wil keep burning the preamp till it reaches at least the effect like 2 days before.
So I do think that now is like a roller coaster. And I will keep writing my experience during the burn in.

[mep]

It makes me wonder about the quality of your electricity. Daytime vs. nighttime?

[La Dolce Vita]

I agree. As a Ref 6 owner it sounds great out of the box. There's some variance as it burns in but nothing like you are describing - that's extreme. How's your electricity? Voltage spikes? Do you use a power conditioner?

Some Arc activity here, nice!

Im experiencing the exact same burn-in effects with my Ref 6, and im only around 100 hours.
I dont even believe in burn in, but its pretty extreme.

Sound was exceptional for the first 60-70 hours, but has changed to one dimensional, overly bright (vocals) and seems slower for the last couple of days.

Hi Guys,

As a dealer of ARC I can tell you that so far my last 6 REF6 sold has been sounding wonderful from start and all of my clients said the same thing from the first minute of starting up the unit the sound is superb.

I believe in the burn in time
But not in the up and down
Sound until the 600hrs

But that's me, I respect each of your experiences

Thake them out and burn properly on the Cable Cocker ;-) Just a thought, the unit sounds great imho. I like soldering and make some test ;-) Does anybody know somebody done that ?

[joeinid]

I would not recommend taking apart your Ref 6 to burn in caps, etc.

Just play it with music and enjoy it. One day you will realize how great it is and say, holy cow! and you will be happy.

Hi Andy,

You raise an excellent point. Some owners, like yourself, love the Ref 6's sound from day one. Other owners need to go fully through the break in process before they find audio nirvana. I would encourage those owners to withhold judgement until the Ref 6 has at least 600 hours on it.

I have loved the sound of my Ref 10 since day one. But I've been told that I will keep hearing improvement until about 600 hours. I'm currently at 250 hours and I'm still hearing consistent improvement in terms of smoothness, refinement and dimension.

Best,
Ken

[slowikpl]

From another member i got this tip:

if you want to burn-in them just get some wires with alligator clips. If the preamplier is turned - off, the capacitors are in a medium -impedance state as the cathode resistor is around 10 kohm and the other wire of the capacitor is grounded by the mute relay.

That would be the best solution. I`m +/- 100% sure that I will not harm my beloved preamplifier ? I was also thinking about this, and even take out the valves out to be sure I don't damage anything.. Can another forum member approve this approach?

Hi Ken,

Glad your experience with the Ref 10 is similar to mine. I do believe with use these components benefit from burn in and settle down to their in age character but the difference is subtle. Sounded great from day one and only better now. The Ref 6 now has a place in my reference system.

Best always...

Hello ,

I’m a proud owner of Audio Research Reference 6 Preamplifier. I want to combine this unit with SS Amplifier the Vitus Audio SM-011. The only question I have will it electric drive the SS- monoblocs via the XLR connection?
The Sterophile test of my Reference 6 says in the measurement: The balanced output clipped at 2.7V into 600 ohms; like the Ref 5, the Ref 6 should not be used with power amplifiers having an input impedance of less than 10k ohms.
Read more at http://www.stereophile.com/content/audio-research-reference-6-line-preamplifier-measurements#IucRsXSulREJtzz2.99

The XLR impedance of the SS Amplifier the Vitus Audio SM-011 is 10KΩ 10KΩ
Read more at: http://www.vitusaudio.com/files/4405/upload/brochure%202016%20v1%2028-10-2016.pdf


And here the predecessor SM-010 was even tested with the Reference 5 Preamplifier with good results.

Thanks Mike for the quick response. I think I will go “blind” for the SM-011 after you and many more people who have advised me this brand in Class-A amplifiers. I hope this will be major step up from my XA-160.5

This is a joke right? Unless you hold IPC solder certifications and have a really good soldering station which includes a desoldering tool, you stand a good chance of causing damage to the circuit board. You will most certainly void your warranty and your value on the used market if you disclose your shenanigans (which would also prove beyond a shadow of a doubt that you are a crazy audiophile) would drop faster than a used prophylactic.

Hi Mep.

I was jest asking myself and also here if anyone has tried this. The outcome by cocking Duelund capacitors after one year of use was beyond my belief! I'm just thinking about speed up this process in Reference 6 and even my thinking is that good capacitors can never been broken in without this peace of treatment! Really! Voodoo equipment!
I will after this reactions not do this to Ref 6.

After chasing and thinking of swapping my long time companion in form of ModWright LS36.5DM with REF5SE and unsuccessful chase for it across Europe I've stumbled on almost new REF6 which I could not resist to, so as of today I finally have an ARC preamp from REF series. Previously I had LS2B and LS16mkII so this should be, from my point of view, a big come back:yahoo1: to the ARC family. Unfortunately I'll have to wait for a few weeks to plug it in due to planned trips, but the longer you wait for something to happen the sweater it gets when you get it :exciting:.

interesting , I absolutely adored my ref 5 and ref 5se [ couriers lost my ref 5!] it had a beautiful textured sound . sadly had to sell for financial reasons but gradually working my way up again . had the 36.5 modwright for a while and then most recently got the 36.5dm . its good and beautifully made but aiming for the ref 6 . now they are VERY rare s/h in uk so waiting for the se to come out . anyone know when that is ?

however a well meaning dealer lent me a grandinote proemio [Italian ] pre and my word that is easily up to the dm level so might persue that as well as the ref 6 as the proemio is SS and no valves to worry about

an engineer I know is currently working on an arc anniversary pre which I saw last week , fabulous engineering !

[bonzo]

Phil, see if you can find the Ref 40 used. It has a separate power supply and if the ref 10 was anything to go by, it will be the dog's bollocks. Just one thing, if you are driving a SS amp (in case you still have your MSB) you might want to check impedance match and the VTL will be better to drive a SS amp.

The ref 40 is similar to 10 and discontinued so available cheaper. 10 is more user friendly and a couple of caps. There is an article on audiobeat describing sonic differences but I understand they are minimal. VTL 7.5 mkII and III have low impedance and put out a lot of current to drive SS amps. I personally haven't compared VTL to ref 10 but you will see that in Roy Gregory's review.
