Not sure what speakers you have. IN building 40wpc Class A mono block amps we recently had a friend bring over his Mola-Mola mono blocks $16K retail with a ton of wpc. After swapping them out, he asked us why to the Class A amps sound more powerful. So unless you really need 200wpc a good class A will perform. But like already mentioned, nothing I know for $3K!
Happy Listening.
