Not close enough I'm afraid,not yet.
Actually, I think comparing power supplies with the same board with measurements would be a worthwhile exercise ... as they would be clearly measurable. @daniboun is doing this with his bamboo 3e 3255 projects - looking forward to seeing the results of his endeavours. He's sent them off to a lab in Germany.

I can think of a better platform where the actuals tests showed no audible difference (far-FAR from it) :

I think it is fun for people to try, but much cheaper alternatives exist. I had fun just to establish for myself. But both the sonic imagery and sparkos are pretty darned expensive I agree. Four OPA1656's for 20 dollars or euros might be worth a pop to hear or not hear a difference. For me NOT hearing a difference between a couple of options was as significant as hearing a difference between a couple of others.I can think of a better platform where the actuals tests showed no audible difference (far-FAR from it) :
Discrete OpAmp Review: Sonic Imagery vs Sparkos
Recently I reviewed the Nord Three SE 1ET400A Dual Mono Stereo Amplifier. That unit came with the Sonic Imagery's 990ENH discrete operational amplifier ("opamp") in the buffer stage (pre-amplifier). The owner then ordered a set of Sparkos Pro SS2590 discrete opamps. This gave me a chance to...
The way I see it, it’s like this analogy: I’m making tandoori chicken. The Freya+ is pouring Tikka Masala sauce on the chicken and rolling tubes is trying different curry mixes for the base of the sauce. Rolling op-amps in the V3 Mono is adjusting the amount of salt & pepper.I think it is fun for people to try, but much cheaper alternatives exist. I had fun just to establish for myself.

Apparently we can quite like second-order or 'even' harmonic distortion so good on @EddNog for enjoying his Freya 2
I think, like anything else on the internet, you just have to filter out whatever isn’t of any interest to you. There’s plenty of discussion in these threads about using the single-ended connections and frankly I don’t find it particularly difficult to just ignore it all (my entire system is running balanced connections). It’s the nature of things on the internet in general.
Opamp rolling is for weak men
. Install Vst host application,and listen music using it. Now you can try the whole bunch of VST effects & find distortion profile your ears&brain thinks is the most spicy.
I willingly ignore threads about things that don't interest me, the problem is that I'm very interested in this product but less than zero in all the imaginative theories and considerations about "salt and pepper and barbecue sauce" that opamps are associated with.
I'm more concerned about confusion I'm being caused by Fosi between op amps operating in sequence vs in parallel!
Not boring to everyone, obviously. It's an inexpensive tweak that may noticeably improve sound quality. I replaced the op amps in my Aiyima A07 Max (two units used as mono blocks) with Muses02, and the change was significant. (I am not sure I would have kept the A07 Max without this upgrade.) I know some people will say I am hearing unicorns fly. Still, I am happy Fosi and Aiyima keep offering the option to roll op amps .
More like the Emperor's new clothes.
Is it not possible for @Fosi Audio to do an RCA optimized version with 100+ sinad?
