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.

"you seem happy and convinced but not so crazily enthousiastic about the change from Capri to Criterion ... am I right ?"

Hi Claude. . .the answer is an emphatic NO, that is not correct. I am extremely enthusiastic about the differences between Criterion and Capri. . . but I am always shy of using any overwhelming superlatives in writing any of my assessments. Fact is that IMO Criterion exceeds the performance of Capri in approx 12 hours from cold out of the box. . . then it is essentially a rising curve, except for a period of instability between 125 and 175 hours of break in. In the end, Criterion -- as a JRDG product -- displays some kinship with Capri in most parameters, but it is a different animal all together. Authority, macro/micro dynamics, harmonic exposure, top to bottom extension, image resolution, and ability to deliver high SPLs without batting an eye or showing intermodulating fatigue are in a different league. What is even more interesting, is that rather than given you a sense that you are 'seeing deeper into the soundstage', it is more like Criterion plops a solid and vast 3-dymensional soundstage into the listening area. The difference is what I would call transcendent.

On the other hand, it is only audio equipment we are talking about. . . any rumours that Criterion has improved my love life are somewhat exagerated. On the other hand, now that I think of it. . . hmmm (grins!)

Concerning DCS, my impression of DCS is that its house sound is always extremely pleasing, sometimes at the detriment of what to me makes music emotional: the interplay of differentially decaying harmonics, and microdynamics. I'll listen to DCS again at RMAF. . . who knows. . . I might change my mind.

Hi Guido,

I lovedyour response ;-)

sic"What is even more interesting, is that rather than given you a sense that you are 'seeing deeper into the soundstage', it is more like Criterion plops a solid and vast 3-dymensional soundstage into the listening area"

I made one time this experience: with the pream Viola Cadenza ... just amazing

It would be great to compare the criterion to this one and also to FM acoustics preamps
Clavil and Brazcole, all of these seem to be worthy comparison projects. . . Let us know your impressions if you have the opportunity of conducting some of them. G.
Hi Guido,

I met yesterday my friend who has had the Esoteric Combo 03, he told me it was not new and had be runing for a while.

Regards
Claude, it's quite possible that the Esoteric sound may simply be not what you are after. DCS seems to me sweeter sounding than Esoteric. G.
