What is it about these that makes them so difficult to drive? I see the mfg. recommends 400 watts! My little Avalons have roughly the same specs (87dB, 5Ω nominal) and I get plenty of volume with my 20 watt Linear Tube Audio ZOTL Ultralinear + integrated (I know, I know, not a real OTL, but that's what they call it) and even on my 8 watt Wavelength 300B amp. I don't listen above 90 dB peaks (and that's LOUD to me, even on Mahler) so I'm using not much more than 2 watts of my amps power. My speakers don't go nearly as low, so perhaps that's what those 400 watts are for. Or, I guess if you have a cavernous room and listen at live concert volumes. I can't do that even when the wife and daughters are out of the house.
Enjoy your new setup, I'm sure it will sound magnificent!
