I have a Synergy IIi mated to a Model 10 amp. It doesn't seem to have any sonic signature of its own in my system. I can go directly from my DAC to the amp and it sounds the same as DAC to pre-amp to amp. At the dealer where I bought it, I could tell the difference between it and a Chord pre-amp, though. The Chord was kind of sterile while the Synergy IIi sounded natural. It is a very nice pre-amp. My only gripe is it doesn't have any single-ended inputs which forces you to use RCA to XLR adapters or get custom cables made. The build quality is phenominal, like all Rowland gear. The display and the discrete LEDs are available in blue as well as green. The blue display is the same one that is used on the Concentra II. I bought the blue version and like it a lot.
I don't think the battery supply is available anymore since the power supply unit also houses the volume display and the IR receiver for the remote control (both quite necessary). The power supply unit has an extra power output connector that is intended to power a Cadence phono pre-amp.
