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: jeffrowland.com And here’s the front view: jeffrowland.com And here’s the rear view: jeffrowland.com 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.

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.
