I have question about frequency response and power issues

My current system is a Son of Ampzilla 2 and Mirage M1 speakers. I am using a Yaqin tube CD player and a Lexicon MC8 in bypass mode for a preamp. My question is basically this. My M1s have frequency response from 20 hz to 20K Hz. My amp has the same specs as does my CD player. My low end is phenomenal , I really am happy with it. I think I may be pushing my amp too hard as the M1s are rated at 250 watts but the amp is only 220. I am thinking about a Macintosh MC302 which is 300 watts output which I think will be perfect for my speakers. I am considering some B&W speakers but the frequency response ratings seem to all put the low end at around 35 Hz. Also the power requirements for the B&Ws seem to be very minimal. I don’t want to lose ANY of the belly buzz characteristics , so am I looking in the wrong direction as far as speakers go? Thanks in advance!

Hi James,

So, as loud as you wish to play the speakers, the amplifier overheats? 

I've looked at the Stereophile review, which is sadly incomplete compared to modern Stereophile measurements, and the Ampzilla specs. I think it's around 220W/8 Ohms and 350W/4. Now, 350 Watts is a lot of power, but it is possible James over-sold it. You don't need more power. You just need a stiffer amplifier with better cooling. 

Also, of course, make sure the amp has plenty of space above and around it. 

Another suggestion is to use them with a sub and high pass filter. That will reduce the load on  your Ampzilla and give you more head room. That doesn't guarantee you won't fry your tweeters again though. :) 

Best,

E
