Thanks for the info on the DIY ONO boards.
Listening to the Zyx Airy3 now Big step up from the Denon DL160.
Bigger soundstage, much more resolving, deep bass, more extended highs, and much cleaner sounding.
When I installed it I forgot to switch the loading resistor and still had the Pearl set up for the 47kohm. I think the cart is almost unstable electrically (feedback) with this load. Just moving the tonearm I could hear vibrations coming out of the speakers. And putting it on the record and off I got huge pops, one of them put my amp into some sort of thermal protect mode I think (got a loud popping noise repeating about 1-2 times a second, scared the sh*t out of me.)
Anyway I let the amp rest for about 20 minutes. Then I remembered the loading resistor. Switched to 100ohms, and everything worked normal again when I turned it back on. No more loud needle noise/feedback from vibration and the amp was okay, as well as my speakers. That was spooky.
