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:

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.

IMO with the factory power cord, the Criterion sounds better with battery, but the best sound is with a top line power cord.

I'd like to speah English well to decribe with more words the magnificent sound of the Criterion and the Model 312.

Take care, bros.
Hi Brazcole, which high end power cord have you liked best with Criterion? What about with 312? Guido
Brazcode, Are you saying that ir sounds better with a high end PC than on battery power alone? Can you explain in more detail?
