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.

Clavil, the monster amp is called 925. I still do not know too much about it. . . a 4-chassis design, operating in class A/B, probably with a switch mode power supply and PFC rectification, probable power rating between 500W and 550W per channel. Price between $45K and $50K.

There is also a new 625 stereo amp: once again, my information is incomplete and not definite: single chassis, 330 to 350 Watts per channel, SMPS + PFC. Listed between $12000 and $13000.

I'll add more info as I learn it. G.
curious, Jeff Rowland suffering the critics or better said the absence of critics from the american press, because going class D (and making miracle with it) is steping back ?

I am surprised
