New Rowland Criterion 2-chassis battery pre

Jeff Rowland Design has just created a page for its upcoming statement-level, twin chassis, battery powered full function preamplifier. Detail is still scant, but a little bit of info is already available, in addition to front and rear view pics. Here’s the page:
http://jeffrowland.com/Criterion.htm
And here’s the front view:

And here’s the rear view:

You will find a few specs already on the site. JRDG should be publishing more info in the next few weeks. I will post here as I receive it. in addition to the published specs that you can read on the page above, here are a very few additional tidbits that I have learned this far:

. Uses Burr Brown TI OPA1632 high speed fully differentially balanced modules.
. Includes phono stage.
. Uses standard NiMH D-cell batteries available in most electronics stores, loaded in 2 rear-inserted tubes of power supply chassis.
. Capable of AC/DC operation . . . will recharge batteries on independent circuit during AC operation.
. Full remote control
. Target price $18K (not sure yet)
. Availability: probably early Fall 2008.
. Will be featured at RMAF in Soundings Hifi suite Marriott 503 or 505 from Oct 10th to 12th in Denver.

And sorry folks, I have not heard this device yet. Nor I have any good third party reports on its sound. Any speculations on Sonics from my part would be just. . . pure speculations. I’ll keep everyone posted as I learn more.

I was unimpressed with the 2 JRDG rooms (Soundings, Jeff was not there). This coming from the owner of a Capri which is a preamp I like a lot.

Of course IMO there were a lot of duds this year at RMAF. However, the minority of rooms that did shine (ironically 3 of them using Atma-sphere equipment) more than made up for it.

Ah Clio09, I see you have the Audiokenesis speakers. I thought that Duke had one of the best sounding rooms at the show. Not only that, Duke is a great gentleman here on A'gon and in person.

I DO think that Atmas colored his system every so slightly. Duke volunteered that he thought that the 60s would have been a better match than the 30s that he was using. Still, it was a very musical system, in my top three of the show, bar none.

BTW, here's my personal top three:
Soundings (Vienna Acoustic/Rowland)
Genesis Speakers
Audiokenesis

I wasn't able to visit every room, so there very well could have been other rooms in this league.

Well.....Did you ever get back for a good listen to the Rowland Criterion? I have one on order and am very interested in anyone's thoughts who have heard it personaly. I don't care to have anyone guess on its sound...I know what his previous pre amps sound like. No need to go there. Just the facts please. Thanks, David.

Kawika, all I can say at this point is that it sounded very quiet and musical in the 312/Dei Musik system. At one point there were about 8 people in the room and Rod switched from the Marantz SA7 to the Playback Designs everyone immediately recognized the improvement in transparency, sound stage and impact. There were a couple "wows" in the room.

When the firmware is finished and the Criterion is operating on battery power, I'll go to Soundings and compare it to the Capri in a more meaningful way. Unfortunately that may be about the time that you take delivery. I think we're talking about a few weeks. The programmer needs Jeff to get back from Asia and push him to finish.
