  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.

Exactly Ed. The Coherence and Capri are Jeff's reference, which are high standards indeed. Talking to him, there's no way this will be a step backward, although I find it hard to imagine how he'll surpass the Capri.

Ed, have you compared the Capri and the Coherence-II?? I be really interested to hear about that.

Lapierre, please don't confuse JRDG's implementation of ICEPower with B&O's. The B&O base unit is just that, a starting point. Jeff improves on that in almost every way imagineable. It is indeed the foundation of his amplifier designs.

Also remember, the Criterion and the Capri are pre-amps, so there's no ICEPower unit in either.

Psag, A'gon isn't all that bad a resouce. Just like with the printed mags and online mags, you have to learn to read the reviewers. Generally I don't think that advertising "buys" good reviews, but the advertisers probably do tend to get reviewed more often.

Anyone in business knows those that smooze and those that don't. Jeff doesn't. To hear him tell it, he tries to be courteous to all comers at shows, but he's not into buying a potential reviewer a fancy meal or "entertaining" such people. If they want to visit his shop they'll be welcomed and shown all the same stuff he'll show others. He's about running his business conservatively and trying to design the best products that he knows how. I doubt you'll ever see him here or on any forum defending his equipment or touting it. He likes the way his web site looks and that ain't achangin', etc., etc.

That makes it a little harder for us to find him, but you can be pretty comfortable that any fame or notice he receives is well earned. I have nothing at stake and only comment about JRDG because I want others to find out the "secret" that I've found. I paid full retail and could have just as easily spent that $9000+ on some other brand.

07-25-08: Dcstep
Yeah, French_fries got it right. SOTA is somewhat like buying a computer or CDP, if you wait until things "settle down" you'll never buy. You just need to pick something near the top of the heap and jump in, then plan to go with it for a few years no matter what comes along.

I'll be pleasantly surprised if the new Criterion elevates very far beyond the Capri, mainly adding flexibility to the Capri's limited switching possibilities. The ability to use the Capri in DC mode by placing the PC1 power factor correction unit in front of it makes me wonder about the value of a battery power supply. We shall see. There's surely a market for two-box, battery powered high-end units, but I think that Rowland may have made most of the performance available at a much lower price in the Capri and Continuum.
