I'm of two minds on this discussion. On the one hand, I had Andras which have been converted to Andra II's, and there is no question that the original Andras couldn't be driven by less than 300-350 watts per side. When I spoke to Eggleston, they reminded me that the A IIs were rated at 200 watts MAXIMUM, and told me any good 100 watt solid state amp would probably be fine although they could handle much more, and specifically recommended McIntosh amps as a great match. By the time the A II's came back from the factory, I had a demo pair of Mac 501s waiting, and the combination has been extraordinary, especially when I added a pair of Purist Dominus speaker cables. Having said that, and having 500 watts available per channel, the fact is the Macs have meters, those meters reflect that the amps never put out more than 125-150 watts on the loudest passages of the largest classical synphonies, and that in my 23 x 13.5 x 9 living room, it would be unbearably loud to open the system up further--and I regularly listen from the eighth row of Carnegie Hall, so I know what an orchestra sounds like going full out. Without getting into the need for reserve output capacity on an amp, I don't believe the Macs have ever put out 200 watts with the AIIs, and I wouldn't rule out your present amps just because they are rated at that level. As to your particular amps, I don't know them well enough. I'd certainly listen before ruling them, or the A IIs, out.
