....but I feel that the M80v2's, even though they are very efficient and will "play" with lesser amounts of power, love the extra "juice." At 4 Ohms the 7500 is feeding them 300 WPC and they really shine...

I apologize for my ignorance but I keep hearing things like 'm80 love the extra juice', or that they 'draw that amp power' and I don't think I understand that. Since they are already so efficient - 95dB/W/m - why do they need that extra power? They are already 3dB louder at the same power than, say, m60.

On that note, 300W into an m80 at the listening distance of 12 feet would result at more than 100 dB sound level. Do you really listen to that loud? I can't comfortably stand more than 80-85dB
