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!
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?
