It will all work together splendidly. And for two π's, I would not consider bi-amplification.If you're near Tulsa, come to the meeting next Saturday. Stage Series seven π's on stock Paramours will be there, and they sound fantastic. Your tower two's sound great on Paramours too. Not too shabby on the Decware Zen either.
We connected both amps to the two π's last meeting, and they both sounded great. The Paramours had more bass; Both the Zen and the Paramours sound great in the mids. The Zen has lower hum, and is a beautiful amp. You won't go wrong with either amp, and I think you'll love your tower two's on either of them.
