@mbmi No GaN FET’s don’t need 100 of hours of break in. I proved this at friends home a while ago. I’d replaced an Orchard Audio Ultra Amplifier that was running for a month with one that had literally 5 minutes of burn in time. Zero difference in audio quality.
@atmasphere As usual Ralph, you are 100% bang on ! Damn & Ron Carter has one of your Amps ? Very cool.
I watched that paid for 31 minute YT of Canada Jay’s and as usual, I was blocked immediately in the comments section.
How the F can you say that the AGD Amp is the ’best" without listening to Ralph’s Amp (which I have heard on FR20’s) or listening to Leo’s Amp (which I own) or even the Underwood GaN Amps. I dragged Jay & his entourage into the Soundfield Audio/Triode Labs Cables/Orchard Audio Room back in February at the Florida show. He never bothered to once mention what he heard. This was on the Friday morning when people’s ears were fresh.
I also heard, met, and talked to Alberto & Ralph at this years Axpona where I was and even worked the Endow Audio/Orchard Audio room on the Sunday so that Leo could finally catch a break. I love Tubes and someone like Ralph is the Guy that can make a GaN FET sound identical to a Tube. Same can be said about Alberto & Leo’s designs. I haven’t listened to the Underwood, Technics, or Peachtree Amps. But if implemented correctly, they can be "magical". I’ve fooled many folks when they heard my rig and didn’t "see" the Amps.
When I told them is an all analog Class D GaN FET Amp. They were dumbfounded !
