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:

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.

This thread reminds me of the "Preamp deal of the Century" thread.
Close to 250 posts BEFORE the preamp actually hit the market.
Remarkable.
Thank you JimJoice, you are correct in that the twin power/data pigtails are shipped with the preamplifier, as such I am definitely breaking those in together with the pre. The ICs and power cord are Furutech Evolution II that I have used in the system since 1st quarter. Rather, as the pre has a lot of transformers (power management, input stages, output stages), I have been told that it may take particularly long to stabilize.

Pinkus, I thank you for your optimism. Of course, in the end, I hope that I will truly enjoy this device. I will try as much as I can to document what excites me, what does not, and most of all, why. If nothing else, I hope that this exercise will help yours truly to clarify the modalities of his own cheery audiophilic obsessions. G.
Yesterday I ask the MBL and Cary dealer to bring to my home the flagship SLP 05 pre-amplifier from Cary to compare with the Criterion. He was excited with the challenge, but after the session he said the Criterion has a more transparency sound and to beat the Jeff Roland only the MBL's top of the line, the USD 20k 6010 pre-amplifier.
Anyway, IMO, the Criterion will beat this device as well.
Thank you Brazcole, what other differences did you hear between SLP 05 and Criterion?
Brazcole,

couls you ask the MBL dealer if your 312 is strong enough to drive the 101E ?

these are truly amazing speakers, which I love too ;-)
