Beerdraft, it might interest you that Victor's partner was a customer of ours and had bought 2 sets of our amps and a preamp. I spent a few hours on the phone with Victor while he had one of the amps open on his bench, trying to model it in P-Spice (that required a schematic and that was why the amp was being examined). Victor was trying to tell me that the amp did not work (in P-Spice) and I was asking him 'did you listen to it?'. Back then (1993 or thereabouts) P-Spice had terrible models for vacuum tubes :)

I can't say after his reverse-engineering our amp that he copied it- clearly he did not as he used a different driver circuit so neither our patent nor copyrights were violated. But it was obviously an influence- minimal number of gain stages (our amp has only one), no feedback, Circlotron output section, triode operation, fully differential and balanced throughout... sound familiar?

Indeed it does and I know lots of manufacturers that test others to find out what they like and or dislike about a unit and will test it in the design stages. Its good to test your competition and see how you compare. I also remember reading a review wrote where Victor met his partner and listened to his system and told him he could build a better amp, so his not then partner said prove it, I think he did. From what I understand he had been building stuff like that for years for himself tinkering with things as a hobby but never did it to make money till he met his partner.

Beerdraft, I agree with you that some manufacturers do do that. I'm pretty sure the rest of that is apocryphal. We heard his amps almost right away...
