Infinity FET Preamp rebuild
The “right guy” would have been John Ulrick, the lead designer at Infinity Systems at the time. He also designed their class D amp known as SWAMP. He went on to form Spectron Audio. He passed away a few years ago. The likely issues might be aged p...

GaN-based Class D power amps (Corrected OP)
The sole purpose of this new thread is to simply correct the errors I had in my OP of the other thread regarding certain amp specs, pricing and products. The other thread will remain—at least I will not remove it.  
Stein Music Maestro Lacquer

What preamp creates the largest soundstage?
I’ve owned BAT line stages, too. They’re great a throwing a huge soundstage.  
Are Pass Labs amps probably the best ever you can buy ?
OP, if you have $15k for only the amp(s), then you should consider the GaN-FET class D amps from AGD Production, Vivace monoblocks. They are $15 per pair. Here is their URL link: http://agdproduction.comTwo forum threads are devoted to GaN-based C... 
How much difference does an anti-vibration audio rack make
