Go with MF A3 if you plan on getting better system in the future. I own several MF amps, including A3, Sam Tellig of Stereophile liked A300 so much he bought review sample! You get beautiful sound with stock unit, but it gets much better with aftermarket power cord and using pre-amp out RCAs to bi-amp with another MF amp.....very flexible and Audio Advisor the US distributor is first class, with 30 day return policy, demos sometimes offered at $850....regards Sam
