Ordering from places like JLCPCB is pretty economical. I hope you did 2oz copper and at least 1.6mm PCB thickness? 10 boards for ~$90 shipped (this for the v1.2 full board).
Nelson Pass apparently mentioned it at Burning Amp last weekend. I wasn't there so don't know what he said about it, but the insinuation was that he was favorably impressed by it.
I know these aren't Stax, but have any of you tried Audeze CRBN2 in lieu of the 007s? Bob Katz seems quite enamored with them using one of Birgir's Carbons as the amp. Kinda expensive, but not sure what 007s are running these days either.

They seem to be some sort of discrete voltage reg made to replace std. 78xx/79xx regs. Sparkos makes some, and I saw some on aliexpress, but nothing that looks exactly like these.
I was recommended LCSC by someone on diyaudio so used them for some LDOs which were on extended backorder everywhere else. I received what I believe to be genuine parts (they work like they should).
