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®.

Just saw the e-mail in my in-box. Don't like that they adopted the new GS styling in the Reference series.

Ref 6 and GS150 could be a KILLER combo!

It's a good thing I'm not in the market for anything :rolleyes: :blush:

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.

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.

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

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", you aren't in what market? :D
"Nelson", you're so terrible!!! Look forward to your thoughts...
 
I tried posting a picture with an interior view of the Ref 6. It shows the 6 tubes as well as golden caps. Looks very attractive.
