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!

There's no need to change your amp.  The difference between 250 and 300 watts is trivial.   Are you hearing sounds of distress or increased distortion from your current system?

I am not clipping but the amp will get hot and shut itself off. Previously I was using the Bryston 4Bs and they seemed to have a lot of punch, the sound I have now seems thin and I don't hear ANYTHING until I am cranked up to about 2/3 volume. Nothing at all at low volume.

Sounds like you need a preamp, as you are probably clipping the cd player

When you say the M1s are rated at 250w, that's almost certainly the supposed maximum that they can handle, not the range that they're comfortable with.  Agree with previous posters.  Also, all about input and output impedances, and matches between components.  Son of A shouldn't be overheating like that.  I don't remember the M1s as being notoriously difficult to drive.  The Bryston likely had different impedance and gain.  Inserting a powered pre-amp in system, with good impedance match to power amp, should be a significant improvement.
