Korryodell,
You have put together a very nice system,it must sound quite good and natural.I find your approach interesting with the 70 watt tube amplifier. I`ve read so often that the maggies really need 300 watts or more of SS power to come alive and really sing. I personally find tube power(in general) amps to be more natural,3D, offer better tone/overtones and more 'realism' than most SS amplifiers. Did you lose any certain performance qualities in going from 500 to 70 watts?
Regards,
