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:
http://jeffrowland.com/Criterion-front.htm
And here’s the rear view:
http://jeffrowland.com/Criterion-back.htm

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.

A friend of mine ask me to listen to his Ayre KX-R preamplifier. He said it's better than the Criterion. I'll go tonite to his home, but I doubt, because IMO the Capri is the same or even better than the Ayre. Let's see.
Brazcode, Are you saying that ir sounds better with a high end PC than on battery power alone? Can you explain in more detail?
Hi Brazcole, which high end power cord have you liked best with Criterion? What about with 312? Guido
IMO with the factory power cord, the Criterion sounds better with battery, but the best sound is with a top line power cord.

I'd like to speah English well to decribe with more words the magnificent sound of the Criterion and the Model 312.

Take care, bros.
I have seen ;-) and heard the Criterion this morning

beautifully build, the front plate is slightly curved inside ...
one curious thing, the two leds produce a white / yellow light, letters & numbers on the screen are blue pale ... ?

I heard it on following system:
Avalon Sentinel
Pass monos XA-160
dCS Puccini with clock
NBS 1 & Transparent Reference MM2

difficult to say anything else than beautifull as I don't know the system well enough to say what differences exist with other preamps ... but I asked to hear with and without battery. Well it was quite clear in "mi chiamano Mimi" with Katia Riciarelli, orchestra and voice sound more calm, warm, the voice is less "rude" in the Forte parts.
Just a quick update. . . JRDG is now doing the final assembly of a significant batch of remote controls and remote control receivers. Things are moving in the right direction. The several units already in the channel at this time are still remoteless. Saluti, Guido
I'll dring to that Brazcole! (means I agree very strongly). I have used the 312 for a year now and absolutely love it. You will see how it opens up when it approaches 1000 hours of playing time! In the meantime, how is your new Criterion doing?
A couple of days ago, I received my Model 312. I was a little afraid to buy it, but I read in another sector of Audiogon that "the sound of the 312 is so transparency that is hard to believe that there isn't tubes hidden inside". Then I buy one. That is true. The Model 312 is one of the best stuffs I've buy in my life.
I have the Odin power cord.
I would like to see a photograph of the Criterion surrounded by the "most beautiful women in the World", the ones straight from the streets of Rio. I am sure Jeff would like to have a shot like that as well. That would be some carnival! :-)
Husk, if you think about it. . . English speaking audiophiles may be very well the only kind of humans in the world -- besides insurance scammers -- who actively plan for their precious property to be 'broken in'! (grins!). . . minor idiomatic misunderstandings are more than. . . understandable. G.
Obrigadissimo Brazcole, I did not know that my name was in the movies. Now going back to Criterion. . . you are probably one of the very first lucky audiophiles to receive Criterionin the Americas. That is why we are kindly asking you to write your impressions on this discussion thread. . . . here are some specific questions:

1. Did you receive the remote control for the Criterion?

2. Criterion can operate both connected to the wall electricity (outlet (AC), as well as on its internal battery. Have you already listened to it both on AC and on battery? Was the sound any different? Can you describe the difference?

Finally, it is very likely that the Criterion will need to be used and make music for a few hundred hours before sounding its best. . . the process is often called 'break in'. Please let us know how the sound changes as you 'break in' the unit. Typical interest points are:

. Brand new.
. 25 hours.
. 50 hours.
. 100 hours.
. 200 hours.
. 300 hours.
500 hours.
. 700 hours.
. 1000 hours.

I have created a Microsoft Excel spreadsheet to help tracking break in progress. I'll be glad to send it to you if you send me an email.

Grazie mille,

Guido
I heard those words in a couple of movies that were English spoken: Get lost, Guidocorona...
That is exciting news Brazcole, please let us know the sound as Criterion breaks in. . . we want to know both sound using battery, and using the power cord. . . and of course tell us what power cord you use on it.
Huh, I'm not sure what you mean by "after JRDG was sold for chineses". Could you explain. I've visited his shop in Colorado Springs, CO as recently as last fall and Jeff was still there with his assembly crew. His software designer is in Boulder, CO and I met him at RMAF.

Asians have been major JRDG customers for many years, but the designs are developed by Jeff Rowland to please Jeff Rowland's ears.

Dave
My Criterion just arrived. I hope the Criterion works much better than my GamuT 3Di pre-amplifier, because people say that after JRDG was sold for chineses, they lost his beautiful sound. I will see.
So I'll receive my Criterion on time (I hope). Of course I can wait more time for the remote control.
Thank you very much, man.
I'm from Rio de Janeiro. And today start the Carnival in Brasil, with the most beautifull women in the world.
May I ask if you think that the Model 312 is really amazing? My loudspeakers are the 802D.
Brazcole, do not give up about the Criterion yet. Units have started to trickle into the distribution channels, although the remote control will be delivered to such customers with a slight delay. As soon as Jeff Rowland returns to the office in early March I'll seek a status update. May I ask where you are located?
I bought a Criterion, and I'm going to receive it at the end of February. But now I'm not shure, because, after I read the posts, I think that there is no one Criterion sent for any customer.
I have a Gamut set up, with 2 GamuTs D200 in bi-amp, and I'm shure that my new set up, with 1 Model 312, will be much, much better.
I decided to buy the JRDG devices after I read the messages in this Forum.
All, because of an emergency in Jeff's family, we may need to wait for Criterion a few more weeks. I'll keep you informed. Thanks, Guido
Apparently. I understand that the issues are now restricted totally to the remote's functions.

Dave
Husk1, no pressure. ;-)

Macrojack, the gizmo factor is low for me, but the thought of retiring my Continuum 500 and going the Criterin/312 route has crossed my mind. I think that the sound is going to be THAT good. Diminishing returns, for sure. The Capri and Continuum are incredible bargains.

Oh yeah, don't forget, we'll need the separate box Critereon phono-pre (another wait) to fully replace the Capri and Continuum with a Criterion based system.

Dave
I use a Capri preamp which I consider to be a very high performance bargain. No matter how good the Criterion turns out to be, the existence of the Capri for a small fraction of the money forces the Criretion and most other statement products deep into the land of diminishing returns. For this reason,and the sheer dollar amount involved, the chances of my ever buying a Criterion are remote. Nonetheless, if the money was in my hand, I would have a hard time turning my back on the gizmo factor. That thing looks pretty trick.
Dave, The whole audiophile community is waiting to here what you think of the Criterion with your MPS-5. BTW you have to sympathize with Jeff because the remote delay seems to be a never ending saga..
We're probably a few weeks away from me lugging the MPS-5 over there, but I'll keep you guys in mind and try to do it.

Dave
Husk, no the remote was NOT fully operational yet. This is a machine with "production" boards, etc., but not released int the US yet, due to ongoing work on the remote. JRDG is right down the road from us here in Denver and Soundings is a long-time dealer; hence, the unit sitting at Soundings, awaiting a firmware update for sales release.

Dave
Husk, Soundings HiFi is in Denver (Colorado). Best way to get in touch with them is by phone at 303-759-5505. The owner is my friend Rod Tomson.
Dcstep, Did the Criterion have the remote working? And where is soundings? Web address?
I heard it yesterday, through a crappy Primare CDP and with music that I didn't know, and the first impression was incredibly positive. The silence from which the music emerged was presented was absolute and the air and details of the recording venue where incredibly life like.

I guess someday soon I'll need to lug my Playback Designs MPS-5 over to Soundings to listen with a good front end, more appropriate for the Criterion/312/The Musik setup that followed the lowly Primare.

Dave
I need to call jeff in the next couple of workdays on some I will call Jeff in the next couple of days and will ask for an update. G.
Video with Jeff Rowland on CES:
http://uk.cinenow.com/videos/2003-jeff-rowland-2009

The system i DCS Puccini, Jeff Rowland Criterion preamplifier and 312 amplifier, Thiel 3.7 speakers and Nordost Odin cables.
Husk01, a limited number of units have been shipped, minus the remote control whose microprogramming is still being finalized. General availability of Criterion will start as soon as all kinks have been removed from the remote control firmware. Guido
Husk01, I have just called JRDG. The answer is yes, not only Criterion supports theater bypass, but the bypass functionality can be mapped by the user to any single ended or balanced input via the Criterion menuing system. G.
Near the entrance of the Rowland room on a table there were static displays of the Criterion and also the Capri stacked with the Model 102 stereo amp. Not sure how Stereophile could have missed the Criterion that was hooked up to the system. I'm just sorry they never had the battery power supply engaged the few times I swung by.
Spoke to Jeff Rowland today, the Stereophile report of Criterion being on static display at CES '09 appears to be one of those urban legends with an unknown cause. . . Criterion was playing music throughout the show, including during the Stereophile visit. Apparently Criterion was frequently being switched between AC and battery operations. Some units have already been shipped in limited quantities in December and January. General availability will commence as soon as a few residual kinks are extirpated from the remote control microcode.
