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.

Someone brought in the soundtrack to "My Cousin Vinny" which was very impressive with bass dynamics and effects, but not musical at all. When we played real music it was a very musical system. As with most rooms there, the operator needed to avoid overloading the room. I heard Rod overload the room a number of times and the guy next door would often overload his room to the detriment of the Soundings room. So, it's not ideal. Bring your own CDs that you know and ask for a level adjustment to suit the music. When you do that, it's actually fairly reasonable way to get a quick and relatively accurate take on equipment, IMHO.
