"Now I also read from others threads that as time goes by Class D becomes boring, no tone, etc, etc. I am a bit confused now and cannot decide which way. . ."
Fear not, class D amps are just like amps of any other class. . . some are great and some are not. I use a spectacularly good Rowland 312 stereo amp, which is coincidentally class D. I chose it because I preferred it over all other amps I listened to, regardless of class of operation. W4S are good amps. . . in class D you can also look at the excellent Bel canto Ref 1000 Mk.2.
