Mrtennis...At least with Maggies, the "quality of sound" delivered at a five watt average power level (about six volts rms into 4 ohms)is better when it comes from a powerful amp although one would think that 100 watts would be plenty. That's my experience, and I am not alone. I haven't a clue why this is so.
By the way, you could actually try a ZR1600 amp for less than the cost of rolling tubes once!
