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:

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.

Hi Braz, Final Model 625 power ratings and related tech specs have not been published yet. We are all still waiting. Guido
Brazcole, you should be careful if you plan using different amps on your speakers top and bottom. I know it can be done successfully, but it certainly isn´t easy.
Thank you, Cappuccino

I was thinking it was something like plug and play, because in the past I used 2 GamuTs in biamp. But with 2 differents amps you might have tech situation.

Anyway, day after day I like my 312 more and more. Well, its bass sound is better than GamuT's bass sound.
Guido, what's up?

I think everybody is waiting for more words about the Criterion?

You are the soul of this forum.
