Jeff Rowland Preamps

In the 90's I owned the Consummate Preamp, I sold it and I missed the later Designs. A few times I listened to Synergy Preamp at Demos but at that time there were so many different Rowland amps launched it was hard to say what was really going on. From my memory I think, in the 90's the Rowland sound was unique compared to others, what is going on today? Question to - current or former - Owners, what's your opinion about the Preamp models you use?

The Coherence II has a few issues, but the batteries are not one of them...

Never read something about it, but info about the Coherence II seems rare anyway. But I saw a few serial numbers, so I guess a few hundred units were sold...maybe mainly Asia?

Synergy was common I think, the Criterion / Corus is probably also quite rare, not many user comments in the web ... where are those?

i was curious on this very subject as to what happened to the Coherence-2, and i was once told by a company rep over the phone that the coherence-2 was "too expensive/complicated to produce". I personally don't take issue with the piece- it's brilliant imho, but i would have to disagree that 4 years in the market is a bit short for a niche product, and the Synergy seemed (to me) to be a place- holder rather than a sonic advancement.

Well FWIW Jeff will be releasing a "break through"power supply upgrade for current units late this year. You can even power an Aeris and Corus off the same unit. Prototype looked to be Aeris sized and machined aluminum chassis. The man doesn't rest!

Did the The Coherence II preamp give you the option where you can plug it into the wall, or you could only run the
The Coherence II preamp from the batteries.
