Previously used the Synergy IIi, and now the Corus. I like both preamplifiers a lot - both musical, low noise and fairly neutral. The Corus was a surprisingly step-up in detail, frequency extension and bass articulation.
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?
