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.

So I'll receive my Criterion on time (I hope). Of course I can wait more time for the remote control.
Thank you very much, man.
I'm from Rio de Janeiro. And today start the Carnival in Brasil, with the most beautifull women in the world.
May I ask if you think that the Model 312 is really amazing? My loudspeakers are the 802D.

My Criterion just arrived. I hope the Criterion works much better than my GamuT 3Di pre-amplifier, because people say that after JRDG was sold for chineses, they lost his beautiful sound. I will see.

Huh, I'm not sure what you mean by "after JRDG was sold for chineses". Could you explain. I've visited his shop in Colorado Springs, CO as recently as last fall and Jeff was still there with his assembly crew. His software designer is in Boulder, CO and I met him at RMAF.

Asians have been major JRDG customers for many years, but the designs are developed by Jeff Rowland to please Jeff Rowland's ears.

Brazcode, Did your Criterion come with the new remote?

That is exciting news Brazcole, please let us know the sound as Criterion breaks in. . . we want to know both sound using battery, and using the power cord. . . and of course tell us what power cord you use on it.
