Do you still have the Wells? Conclusions drawn?
Good Amp, big sound stage, but very similar signature to my SS Odyssey Kismet amp I am looking for a 2nd amp standby amp basically a tube amplifier or 2 mono amps , I have had a couple of Class D amps in the past Peachtree Nova 150 ( very dark background Very quite and Wyred 4 for Sound , GR8 amps but class D do not appeal to me , I guess personnel taste
for the money these QS silver mono tubes are amazing "very wide band width tonally accurate correct the Bass on these at 40 watts match's both my Odyssey kismet and the wells at 1/3 the price ! very stable Possibly I may end up with a DS Kooteney to match with my DS-2 pre-amp. But these QS mono have got me enamored and they are 1/2 the cost ! Mark Sanders also have a new 50 watt mono amps with a different sound signature I may get a chance to try that one out also !
@dodgealum
read your review on the LTA Ultralinear in Audiogon and did talk to mark , got some pictures of inside guts from him I may get a unit from him to try it out under the 14 day trial period , but it has SMS switching power supply makes it a hybrid , I prefer Toroidal transformer or the output Transformers based on known and tested designs of the past after all it is really the power and power transformers that we are listening too, Paul Macgown in one of his video blogs said so much recently that they have tried Switching power supplies in PS audio products but they do not match the sound quality regular transformers and my 'ears" agree with that !

point to point "short signal path wiring " no circuit board " low noise tested Transformers ) at the end it is the SQ ! that matters I guess
