Lostbears named a amp I completely forgot about as I had cary Slam 100's on the m2's with 95 watts triode;excellant sound but just was not enough to really control the panel when volumn level was increased; although this is a very good amp;if you can find one with the ultralinear switch which increases power to 160 watts it would be a amp to consider;I also think going used gives you a lot more amp for the money and on resell you don't get beaten up to bad with the $$$$.
