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.

Bill's royal self image has him confusing a coronet with a cornet, neither of which has to do with cars.

My grandfather did own a Dodge Desoto with push button gear change, but then he wasn't much of a car guy, like Bill.

Bill, if you'd like to meet at a road course or autocross somewhere, I'd be willing to bet that I can beat you soundly, no matter what you drive. If you're coming to RMAF I could set something up. What do you need to make it interesting? I'm thinking 1,000-bucks or maybe 5,000.

In other words Bill, for your private edification, the link below will take you to a fine site, were you can learn about cornets, trumpets, flugelhorns, and mayhaps flumpets -- none producing noxious exhaust fumes but all powered by the clean exhaust of our lungs -- to your heart's content, including that very Olds (sic) Ambassador cornet that I am interested in. . . a fine beginner horn to all accounts. . . aledgedly highly recommended, if you were ever keen in blowing some steam without breaking the bank, after which I hope you will become cheerily inclined to contribute to this and other Audiogon discussions with topical and constructive posts.

BTW Guido, three working valves will be enough for all but the rarest cornet or trumpet. Flugels often have four valves as do most piccolo trumpets, but seldom cornets and trumpets. You might like a mellow flugel, but the picc is an evil little beast that only very experienced trumpeters can handle.

I could say I'm a intermediate level audhiophilo, but I'd like to share my discovery.
Before I bought the 802D I had a 803N that I keep with me. Today I was still in shock because of the 270º sound of the MBL 101E that I listen 2 days ago.
I use both channels A and B with 2 pairs of speaker cables in my Model 312 in bi-wiring. I decided to make something to improve my sound. I took my old 803N and bring to my set up. I put it beside the 802D with 50º degree.
First I disconect 1 pair of cable in the 802D and use a link cable. So I conected the disconect cable in the 803N and also use a link cable because now my both speakers are single wiring.
I turn on my set up.
Unbeliable sound. Amazing sound. The sound was in the entire room, like the MBL. Everything improve. The transparency became much better. I don't known English well to have words to explain the HUGE change.
Now I known much better what the Criterion and the 312 can do.
Sorry if what I said isn't new for the audio experts, but I'm still learning (this path is very nice, pal). I read many sections of Audiogon, and I learn with many people, as Guidocorona, Dcstep, Racquel, among others. Now I only want to change my speaker cables and XLR cables. I think Kimber Select could be a good choice.
Anyway, I recomemd you all to have a experience with 2 speakers in 45º or 50º degrees. Amazing!! I'm knocking the heaven doors.

Thank you Brazcole, Kimber could be interesting.. . but every time I heard that brand I found it to be a little hard sounding. I am having a great deal of success with Furutech wires. I use Furutech Evolution II ICs, speaker wires and power cords to connect all my equipment: TEAC Esoteric X-01, Capri, Criterion 312, and Vienna Mahler V1.5 speakers. G.
