When I was searching for my amplifier (mostly among class A ss amps) I found used Spectron then upgraded it then buy another one and ...stopped.
During these last few years I upgardes my speakers from Wilson W/P-8 to Sasha also by Wilson, preamp first to Joule-Electra LA-300 and then LA-450 (yes, its better !) and lastly, with Simon's help Still Point E-SS rack (bloody expensive but WORTH EVERY PENNY AND MORE !!!!!!!!!!!!) as well as a few more smaller things.
I tried a few more power amps (more because of curiocity) and every time concluded that my Spectrons are the best (for me at least) and I can and I do build first class stereo system.
The Spectrons are the basis of my "pyramide" and I am immensely thankful to them not only for their power amps but also for the highly qualified advise I always get from them in matching components etc. I attrubute it to the simplest fact that Simon is former concert pianist and he has professional "ear" and very few designers in the world are TRUE professional musicians (albeit all love music!)
Mike.
