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.

I was at Soundings with Guido and Dave and agree that the 312 was a much better match for the VA Die Muzick than the Boulder 2060 was. I also listened to the Criterion on the smaller VA Mahlers with the 312. I was impressed with this set up. It was transparent and musical. It also had good tonal balance. The presentation was a bit smaller than the Die Muzick though. It was a shame we could not swap the Rowland and Boulder preamps to compare them.

Sean,
I was pleased that Soundings was agreeable to switching around the amps and even putting the Continuum 500 in place of the Boulder 2060 and the 312. I'm glad we went on Thursday before the crowds came so that our request was reasonable.

I'll get back over there soon and compare the Continuum 500 to the Criterion/312 combo. That will be interesting.

BTW, it was nice meeting you and sharing a great Indian dinner with you and other friends, new and old.

Hi Dave,

I had a great time and was glad I met you guys.

The guys at Soundings were very gracious hosts. In fact I have never been treated better at any other stereo store. I did not mean to imply that they would not have let us try that combo. It would have been a big pain to switch them out and that is why I did not ask them to do it. Especially when they were getting ready for the after show party the next day. I think I spent about 5 hours there that day. That is the longest I have ever spent in a store auditioning a stereo. Of course if Guido had not been there to talk to I probably would have got bored and left much sooner. ;-)

Thanks for the company and I hope we can do it again next year.

Cheers,
Sean

Which makes me think of the FM Acoustic, another amplifier that I liked a lot, but the six-figure price was offputting and it was not clearly superior to the trio that I mentioned before.

could you tell which FM amp & preamp you have heard and how it was?

thanks
