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.

Brazcole, Jeff Rowland also uses Nordost Odin power cords, Interconnects, and speaker wires in his own entire demo system.

Will your new friend replace his AYRE KX-R with a Criterion?

Brazcole,

enjoy your new Criterion. I am convinced ... as we speak, I am using my KX-R to hammer in some nails into my wall (need to hag a picture). I will pick up a Capri as soon as I can.

I wonder why JRDG seems to be using Cardas inside his products and Odin outside, these are two completely different cables from the caracteristics they have

Naaahh, Pinkus, using the KX-R as a hammer to hit some nails into your wall is a crapshoot at best.
You can keep this preamp if you want. Very beautifull sound, no doubt about that.
On another note, I always think that flat cables for speakers was a bad technologie because only very few companies make those cables, but I think I'm very wrong, because if Jeff Rowland uses the Odin flat cables in his speakers, this cable must be extremely good.

Clavil, JRDG has used internal Cardas wiring for many years in its products. Conversely, Jeff has adopted the Odin external wires in his own stereo system only very recently, in the last several months I believe. G.
