If the PS Audio Stellar 700M is as great as all the reviewers say....

This question gets asked a lot and it all comes down to weird market timing.  There is no real reason why a certain product will have a lot of used "for sale".  That being said, I have heard this amp.  It's really not a bad amp for the money you are spending.  Good resolution and neutral sonic signature.  There are better amps, but of course much more expensive.

Have not heard them but I’ll bet they probably are. 

I had a pair and enjoyed them, but at the time Tweakaudio introduced their EVS1200, based on dual IcePowerAS1200 modules, which he highly tweaked. The price was about the same as the M700s, but with ~3Xs the power. A few months ago PS Audio introduced the M1200s, but at $5995

I liked the S300 a lot...I only see one ad for M700's for sale...

I have a Stellar S300, haven't heard the mono blocks yet.  I bought it about 6 months ago to replace a blown aged amp as a "temporary" measure until I could find something more permanent.

I was so pleased with it that I have no plans to replace it.  Maybe sometime in the future, but a new amp was moved to the bottom of my priority list.

I imagine the mono are similar, they're based on the same tech.
