Could not agree more with your excellent review, Greg! I also just picked up a pair of Sparkos opamps for position 2 in my monos and was blown away by the difference it made. I also upgraded the others to the modest but long time well regarded and affordable LM4562 opamps. I also picked up a pair of cheap figure 8 to standard IEC adapters so I could use high quality after market power cords on the power supplies - wow, here again, very nice improvement. These have quite frankly unseated a Pass DIY 40 w/ch class A amplifier called the Burning Amp 3 (circuit Nelson Pass gifted to the community) that’s kin to his First Watt line. While it sounds beautiful, the Fosi’s are surprisingly better, it’s crazy!
Agreed on all counts. My personal experience with the Sparkos upgrade was with the Fosi ZD3 Dac/Pre. The result mimics your description with the Fosi power amp.
Thank you for covering this. I have the same Sparkos upgrade in my Fosi BT20A Pro. And yes it’s more of the good things I hear. I hope you dig further on this topic. Few have your vast experience in this space. Appreciate your approach and honesty. These little amps can embarrass quite of few others. Some can’t except that fact. I one the other hand would have no problem saying so. I have vintage Adcom and Nad I should compare. All the best.
I know who that picture is to your left behind you but it kind of looks like Putin. I really like your large Fred Flintstone chair. Enjoy your videos, always happy when I see them.

Terrific review!
I put a dual single sparkos in an ole Stereo 2 channel receiver STRSDE197. It makes a.grand difference.
I could well imagine someone modding a few of these to assemble a multi channel system with some decent finesse and clout for not so much cash.
