I have the WA22 and am very keen to get a solid state amp to complement. Should I jump on the M9?
Haven't compared them side by side, but the M9 has really wowed me. Not that I am getting rid of everything else, but it solid state at its best. Crystal clear yet warmish and not bright/hard/edgy. Great tight and full bass - that is probably where it has its main comparative advantage to the WA22 - but I'll have to come back o that when I get a chance to rig them both up. And it drives the HE6 veeeery well (so you can trade your HD800 for one and go totally ortho ,) The HE6 actually sounds good on the WA22 too, but in a lush and sweet but slightly underpowered way - not optimal. HE6 + M9 however is really really great =) The LCD-3 is great too - but I have just been spending most of the time with HE6, that's why I keep babble on.
