Hi jscei,
I have the Benchmark amps - I have paired them with several preamps, including very high end ones (Esoteric Grandioso C1), but the best association I have so far is with the Coincident Statement Line Stage, which has true balanced connects. You also have the model with the phonostage included. I have the one without phono, and using upgraded Psvane WE101D tubes. Absolutely fabulous. Never heard so much high and lows and beautiful mids, just an excellent combination of tube with transistor - it will enhance the qualities of the Benchmark (clear and detailed sound with enormous attack and dynamics) playing very close to a very high end system. In time, if you can add a second Benchmark bridged in monos, you would have total control of the speakers and added image/soundstage precision.
