One rarely sees the coils placed perpendicular in class D amps. This seems like a sensible things to do. It’s clear that the bulk of the magic happens in the feedback or driver circuitry underneath the black cover.
Axign IC in there?It’s clear that the bulk of the magic happens in the feedback or driver circuitry underneath the black cover.

Good job!All photos fine here too. Saved them here too:

You think you can listen to an amp and know if it’s class A, AB or D?Does it sound as good as class A/B though ?
Having all that stuff is no proof. Did you ever do a double blind test?Yes, I can also tell the difference between ESS chip and AKM ( I assume that to be the difference ), I have both SMSL M400 and Gustard X16, M400 is both my and others preference, measured spec is nigh on identical.
I have had Hypex NC 400 before Benchmark AHB2.
Probably just serial numbers or other identifying text.What's up with the blackout rectangles? @genfreeciv did you make these?

Yes, that's right.Probably just serial numbers or other identifying text.
Correction: You believe you can tell. That surely makes quite a difference.Yes, I can also tell the difference between ESS chip and AKM
Nah. The IMD is already shown to be practically inaudible, and the HD in this region would only be 2nd and 3rd order. Both are not easy to discern and at their levels we can expect from this amp, won't be audible at all in the high treble region.The PA5 is not as stunningly god above 6kHz, (just pretty damn good).A decent AB amp would likely perform somewhat better here(but there are countless examples of "hi end" gear that does not)but would also be much more expensive. My point is, for a trained ear it might be possible to hear this. I don't think I could though But it is at least plausible others like misterdog could. Then there is the question of preference, lets not get into that...
Below is a measurement of the PA5 measured with a very flattering 20kHz BandWidth but also "proper" bandwith which is more fair when comparing with Conventional amps
seems not possible because the max switching frequency of the MA5332MS is 500Khz, Amirm reports a switching frequency of 600Khz that fits particularly well with the TPA3251 as xrk971 suggested post #240Here's my highly uneducated guess. Two bridged Infineon MA5332MS chips with black magic feedback inside the can.
Uh huhYes, I can also tell the difference between ESS chip and AKM ( I assume that to be the difference ), I have both SMSL M400 and Gustard X16, M400 is both my and others preference, measured spec is nigh on identical.
