Different model, but I have really enjoyed my Musical Fidelity Tri-Vista over the years. And small tweaks have made it that much more satisfying (upgrading power cord and umbilical cord(s). It has dispatched some pretty good separate preamp/amp combos over time. Good to hear that the M6si is also satisfying. I'm not really in the market right now, but I would like to hear a pair of their current M8 700 watt monos.
