1) sure, I listened level-matched (TacT preamp has one big frigging number showing you the dB peak level ;-) and my comment holds for bass at high volumes, at low volumes less power did ok, from about 70+ on, bass started to fall off with less amp power.
2) agreed (but the 10k$ amp was better though, especially on guitar ;-)
3) will do
4) TacT seems to measure that low, at least when you look at graphs (it has an individually calibrated microphone and software with each unit, since it's pricey gear, not surprising ;-)
yes, I'm happy very much with the m80s after tactifying my music, but I assume for most people a TacT or even couple of good quality eqs are expensive (read the equalizer thread, very interesting) so they may have issues.
