Beavis, I think your comment regarding the impedance curve of a speaker is truly overlooked.
I'd been told that my ProAc Response 2.5s despite their 86dB sensitivity rating would be SET friendly because of its mild impedance curve. To be honest, I have no idea what the impedance curve of my speaker looks like, but this weekend I found that my new 37wpc Bel Canto SET40 has more than enough beans to drive my ProAcs to very high listening levels. I was quite surprised to find that it had nearly the dynamics and bass weight of my BAT VK200.
