Aren't the WP7 93dB efficient? You've got to hear those with the Lamm ML2.1 18 watters. :yes:
I would certainly beg to differ.
Great as the ML2 are, and with due respect, I dont think the WP7 would perform at its best with them.
I have tried first with the MC402, up the bet to a pair of MC501's and then MC1201's and know what? Every step of the upgrade brings forth better performance from the WP7. And the volume setting is always at the same value!
Similarly, went from 2400 watts per channel (bi-amp) on XRT30's to 390 watts (tri amp) and the difference is there. Of course, without complex musical passages almost everything sounds the same. But when the music comes forth, power and grip does makes the difference, especially in the lower/lower frequencies.
Power does makes a difference, and certainly, I believe only Horns with efficiency like 98db and more would really benefit from these smaller wattage excellent amps!
Owning a pair of pseudo horns (isobarik bass, horn midrange and ion plasma highs) at 91db, I am pairing them with a new pair of MC501's (for now) and am still evaluating if I should up the ante to a pair of MC1.2k's. So far, at normal listening level, everything sounded fine, especially coming from the venerable MC501's.
Of course, there are exceptions to the rules in "taste", where midranges and highs performance ranks above total performance. To me, there is no one system that could "be all and end all" - or maybe there is and I stand corrected, but certainly, I am not in that league to have audition nor even dare to dream about owning.
Serge, the MC501's are great! Keep them!:thmbsp:
Cheers!
