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?

The Coherence II offers both options. Normally it is plugged into the wall and that charges the Batteries (while playing or Standby). Plugged in, the Coherence II uses the mains from the wall but you can also push a button that it runs on Batteries only ( BATT or AC ).
