The Sound Comparison Test

This article is open to debate so please give us your comments. What would you say is the main difference in your (our trusted reader) experiences between Thermionic Tubes, Bipolars and Mosfets in amplifier sound.

 {jcomments on} I ran an article recently which gave my version of what I hear and believe.  I built (actually slapped two 100W R.M.S/8 Ohm MOSFET modules together and it blew a colleagues Bose speakers to pieces. He was running a Phase Linear 200W (about 1971 vintage) into these speakers but when he heard the MOS amplifier he could not believe the sound quality. The phase linear amplifer ran a +/- 70V rail, had previously blown and some wise owl had used 2N3055 (8 per channel) as the replacement output devices. I doubt this ever worked but give the devil his due – I didn’t hear it before it blew or even while it was ‘testing’. Foot in mouth 

So give us your feelings and possibly, if so inclined – advice!
