Again the topic of weight of amps

I suspect Michael Green might be on to something when he says he went to very low mass systems, especially low mass amplifiers. If thy eye 👁 offend thee pluck it out. It’s no secret that big honking transformers produce toxic magnetic fields that distort the sound and that transformers produce mechanical vibration that affects everything in the chassis, especially given that transformers are bolted down to the chassis.

     When threads request equipment recommendations like this one, it seems that readers for some unexplainable, unhelpful, strange and annoying reason, often consider these types of threads as invitations to just blindly name whatever gear they happen to use. 
     An example? miketuason reads the OP's request for a high quality, good performing amp in the more reasonable 55 pound range and he inexplicably gets the urge to post:
 "I have the McIntosh MC601 monoblocks 600watts, only 95lbs each." 
     ONLY 95 pounds? What? EACH? What the F? Why would anyone feel the need to post this?  How exactly is this relevant? Or helpful? Doesn't this poster realize his amps are roughly double the requested weight.....EACH!  Why did he feel the need and take the time to post at all, right?

Yes, Class D amp technology enables amps to be much more efficient and much smaller. For high end, check out Bel Canto ref600m amps for example. Or even the Fosi amps on Amazon, which are most affordable and about the size of a pack of cigarettes.

Now as soon as they can get them to sound like music and compete with real amplifiers intended, designed, and manufactured for use in Music Reproduction Systems then they will really have something.

Class d is ok for subwoofer amplifiers at least until you compare them to something better such as Bryston or Pass. 

I agree with clearthink on the issue of Class D amps. Havent heard one yet that I have liked.
