Has anyone heard Soundstream M3 THX amps

Unfortunatly, Soundstream was much better at making car amps than home theater. The original car designs were Nelson Pass circuits. You would probably do much better with any of the other amps you mention. Plus, all of them will hold their value more so than the Soundstream.

Good Luck,

Stewart

thanks for the info, that helps.....Jeff

 The car amps were Krell designs made in US. No idea of the junk selling now. Not 100% sure if Krell designed the home gear.
