Iím using Electrocompaniet EC-4.8 pre-amp and their AW-180 Mono-block power amp for years, I enjoy EC sound but they donít have any new pre-amp for long time. Recently Iím very interest in Jeff Rowland's Corus and I saw many Corus users are using other brandís SS power-amp with their Corus and the result are very good, one of the most common example is Passlab power-amp. Does anybody know if my AW-180 power-amp can match with Corus? And do you think if any improvement in sound quality if I change to Corus? THX

PS: I use Esoteric K-03X CD and SACD player, Avalon Opus Ceramique speaker, Audience AR6-TSS power conditioner

Corus has a high input impedance of 40K Ohms on its balance and unbalanced line inputs, and a uniformly low imput impedance of 60 Ohms on both balanced/unbalanced outputs. This makes Corus compatible with just about any CD players and amps on the market.

In particular, I have successfully used the Rowland Criterion -- same circuit as Corus with the addition of a battery-based supply -- for several years with Esoteric X-01 and K-01 players... Truly marvellous results.

You can't go wrong with Corus... It is a very resolving preamplifier, and amazingly musical at the same time.

Hi Guido
Thanks! What about ARC Ref 6? Which pre-amp you think is better match with my EC AW-180 power-amp? JF Corus or ARC Ref 6?
Both per-amp are famous and not cheap, I need to be very careful to make my choice.

Hi MM, what is the input impedance of your EC AW-180? And what is the output impedance of ARC REF 6? Compatibility between pres and amps depends on impedance matching.... In the case of Corus, the pre should be compatible with any amp with an input impedance of approx 1500 Ohms or higher.

As for what is "better", it is purely a matter of preference.

What kind of music do you like to listen to?

What are you looking for in sonic /musical characteristics?

How does your current system fall short of ideal?

What would your ideal preamplifier do that your current one does not do?

Hi MM, as your amp has a very high input impedance of approximately 220KOhms balanced, there is no worry whatsoever about its compatibility with either preamplifier.

One thing to consider is that ARC preamplifiers tend to go through 6550 tubes as fast as kids go through candies... The 6550 in the power supply probably needs replacement after 1000 (1K) hours... 6H30 tubes should last 2.5 times as much before their sound starting to sag.

But compatibility and tube life are by no means the only criteria for choosing an amp... So, here are again my original questions:

What kind of music do you like to listen to?

What are you looking for in sonic /musical characteristics?

How does your current system fall short of ideal?

What would your ideal preamplifier do that your current one does not do?

Best regards, Guido

Hi Guido

Here is my answer of your questions:

1) What kind of music do you like to listen to?
I only listen to modern Jazz music, Bossa Nova. Here are some examples for you, you can listen to the sample:

http://www.amazon.co.uk/Hope-Lars-Jansson/dp/B00004T9XS?ie=UTF8&ref_=pe_385721_124915011_TE_3p_dp_1

http://www.amazon.co.uk/dp/B000QGEVYY/ref=pe_385721_124402661_TE_item_image

http://www.amazon.co.uk/We-Will-Always-Be-Together/dp/B000TLYHZO?ie=UTF8&ref_=pe_385721_124402911_TE_3p_dp_3

http://www.amazon.co.uk/Bossa-Nova-Jazz-Masters/dp/B00000471N?ie=UTF8&ref_=pe_385721_124402911_TE_3p_dp_1


2) What are you looking for in sonic /musical characteristics?
The idea sonic or musical characteristics for me is good 3D stage with silky smooth highs & mid-range, solid bass, very good transparency with good tonal texture and density.


3) How does your current system fall short of ideal?
Iím using my per-amp (Electrocompaniet EC-4.8) and power-amp (AW-180) about 4 years. Before this, I use their ECI-5 for 3 years. I enjoy EC sound, which is neutral with a little bit warm, slightly sweet, nice transparency. But after 7 years, Iím interest to try something new, which is much better than my EC sound quality. Perhaps I will also upgrade my AW-180 power-amp in the future but not now, because my budget is not enough at this moment. Also I have small listening area, which cannot allowed me to use very big power-amp (like Passlab, McIntosh). AW-180 is a pair of small mono-block that fit for my home. And it drive my speaker very well (Avalon Opus Ceramique).


4) What would your ideal preamplifier do that your current one does not do?
More transparency sound, better 3D stage, more silky smooth on the high and mid-range, more solid base, with better tonal texture and density.


PS: ARC Ref 6, this is another target per-amp for me beside JR Corus. But Ref 6 is a tube-amp, the tube has limited life-time, and the size of Ref 6 seem to be a little bit high for my audio rack. Ref 6 has about 7Ē height, my audio rack has only 8.5Ē. ARC ref 6 upper case is quite hot as I heard, Iím afraid my audio rack donít have not enough ventilation space to move out the hot air. These are my biggest concern for Ref 6. But Corusís size is very small, I have no problem put it into my audio rack in anytime. However, sound quality is no. 1 for my decision.

From an electrical point of view any preamp will match with your amps due to their high input impedance (a German magazine measured it to be 600kOhm). But no one can tell you if you'll like a certain preamp combined with your amps, especially in the context of your system.

My recommendation based on what you're looking to gain is the Audionet Pre I G3 with one of their external PSU.

I heard some good comment about Audionet, unfortunately they don't have a distributor in Hong Kong.
BTW, may I know which is Audionet's flagship pre-amp: Pre G2 or Pre 21 G3?

Anatta
April 1, 2016, 08:54 PM
Officially the Pre G2 is the top model, but the Pre I G3 is newer, has better specs and can be enhanced with one of their external PSUs; it's also less expensive and better looking IMO.

Since you're in HK I'd get the Accuphase C-3850 at the great Japanese price, top pre that will also give you the upgrade you're looking for. The user Harris4crna here has it.

Accuphase is a very famous in Hong Kong in this business, they have many users in here. Iíve listened to it many time, it sound nice but not my cup of tea.

I wonder how's the Audionet Pre 1 G3 + power-amp (AMP, MAX) sound quality compare with Electrocompaniet? Do you think they're in the same level? Does they have similar sonic /musical characteristics?

Anatta
April 2, 2016, 04:59 PM
Don't have experience with EC, but Audionet is at the Soulution level at a reasonable cost. It is a very transparent, holographic, high speed, high resolution, low distortion gear, with deep and tight bass. Not warm sounding though if that's what you're looking for, but not harsh at all. The AMP model is about the same size as your AW180s.

I see the Audionet distributor is in Shanghai; maybe it has some dealers in HK? There's also a distributor in Taiwan.

AMP is very shorty, my AW-180 power-amp is almost same size with Audionet's MAX, same height (11.3") and same width (8.5") expect MAX is 1 inch longer than AW-180. If I have chnace I would love to listen to Pre 1 G3, EPS G2 and AMP/ MAX. May I know what is the net selling price of these 3 Audionet products in U.S. now?

Unfortunately I have no chance listen to Jeff Rowland Pre-amp + Power-amp combo very clear before, but I will make a booking later with JR's dealer. If you don't mind, could you please describe the sound character or music characteristics of JRís Corus ? I heard it is more neutral, a little bit warm (but not as warm as Passlab). THX!

Anatta
April 3, 2016, 03:05 PM
Don't know the current US prices, but these are the prices in Germany:

Pre I G3 €4000
EPS G2 PSU €2000
EPX PSU €5000
AMP €10000/pair
MAX €16500/pair

No experience with JR.

April 7, 2016, 10:18 PM
I'll test a Corus with JR 625 S2 and Avalon Indra in soon, let see what happen. BTW, I have test an ARC Ref 6 per-amp this week, very impressive, the sound are so beautiful, very musical. I hope Corus will impress me as well.

My Ref 6 test report is here:

If you choice Corus, please notes, that you can adjust the volume for each entry XLR and RCA.
There is 4 XLR for connecting 4 mono amplifiers or 2 stereo amplifier.
One of two can be adjust if you decide to take a tube amplifier(for medium and treble) and a transistor amplifier ( for bass).
One entry can be transform in BYPASS if you use home cinema like me.
There are 2 records two.

Very good preamplifier, but be careful with the choice of cable.

Another thing : you can upgrade Corus with a external PSU(thanks Guido)...So you can upgrade year after year the musicality of your product.

September 12, 2016, 05:18 PM
Hi Guido,

No I don't get it because Jeff Rowland is not know in Europe and in France.
My dealer stops to work with Jeff Rowland because the distribution has changed.
When distribution has changed, all stores and all distributors in Europe have sold out Jeff Rowland...
I have note this when I search price of Jeff Rowland in audiomarkt.de .
Anyone doesn't work with the new distributor in Europe.
Why ? I don't know but I'm sure there are good reason.
So I think Jeff Rowland does a bad choice to give distribution to the new distributor.
Wait and see the futur.

Regards

T.

hongkong - What you describe is a common situation when a brand initially changes its distribution. Hopefully Rowland selected a reliable new distributor but it may take some time for them to establish relationships with new dealers to properly support the brand. Unfortunately for most audiophiles like us patience is not one of our strengths when we yearn for new gear. :(

I just borrow a friendís Capri preamp to my home last week to test the sound. Wah! it really match with my Electrocompaniet power-amp, it sound very since. So I think if Capri can match my power-amp, then Corus should even sound much better.

GuidoCorona
March 17, 2018, 02:06 PM
Corus has a low output impedance of 60 Ohms on both balanced XLR and single-ended RCA outputs... As such, it will be very compatible with your amp.

Yes, you will find all aspects of audible performance of Corus to be superior to the Capri S2, and even more so to the original Capri.

What is even more intriguing is that the performance of Corus soars even much further if you feed it through the Rowland Power Storage Unit (PSU)... This is a full chassis power supply based on ultra-capacitors which isolates Corus circuitry completely from the dirty AC grid by converting AC into DC, storing the DC, and feeding the uncontaminated DC to Corus... I use PSU on my Rowland Aeris, and results are incredible to say the least.

Hello HongKong.

What is making you consider an upgrade from Rowland 625? Power? Resolution?


For one thing, the Accuphase A200 seens to deliver 100W in stereo mode over 8 Ohms.... All I found is that in mono mode, the amp would deliver "even more".... THis suggest that power would not double in mono/bridged mode.



Conversely, the original model of M625, delivers 300W over 8 Ohms. The S2 version outputs 325W/8 and 600W/4.

The S2 version is much enhanced over the original, which was already a stupendous device.... Is your 625 an original model? If you call your dealer or distributor, they can arrange for the upgrade to S2 status. Not sure what the upgrade price might be in France, but I know it is quite reasonable in the US.


If you needed even more power than the Rowland M625 S2, the new Rowland M535 in mono mode will deliver 900W/8.... All reports I have heard about this amp point to it being quite spectacular. I may be receiving a unit to evaluate in the next few weeks, and will post my detailed findings on Audioshark.


Regards, Guido



I am not sure if you would find the Accuphase A-200 to be an upgrade from the Rowland M625... Even if your M625 unit were an original model, and not the much enhanced M625 S2.

Hello HongKong, if power is no concern, upgrading your original M625 to S2 status is the way to go.... All who have performed the upgrade have been amazed at the result... Jeff has added 4-pole Jensen capacitors in the power supply, and changed all boards to very low dyelectric ceramic boards.... But most of all, has designed for S2 a brand new circuit subsystem that reduces distortions to unmeasurable levels.

HongKong......I owned the original 625 and had Jeff upgrade it to 625 S2. It improved on an already superlative amp with more transparency and even better bass. Unless one is needing more power/current than the 625 S2 provides, I think it is about as good as a stereo amp can get.

Hello HongKong, PSU can be purchased either bundled, or unbundled:

* Bundled with Corus,
* Bundled with the Aeris DAC,
On its own.

Each Rowland national distributor manages its own dealer network... The Rowland factory does not determine which dealers there are in Countries outside the USA. So, for France, you should call Alter Audio and speak to Sebastien:
