Having looked at a fair amount of ebay listings myself, it seems many of the Chinese sellers offer a variety of designs (of course, sans schematics), which would seem to make it difficult to depend on a review unless you also bought from that particular seller. Then there's the concern (at least for me) over counterfeit parts. For example, a guy posted on the Asylum that he bought new, stuffed boards for one of his Dynaco amps from a Chinese ebay seller. They came with Wima coupling caps and some generic pF caps in feedback locations. He said it sounded bad until he replaced all the caps. Wima caps are inexpensive, but I guess if they can save a few pennies by counterfeiting them, they'll do it. Maybe some Chinese factories actually use Texas Instruments voltage regulators and genuine Schottky diodes in their builds, but I have serious doubts about that. I agree that DIY is a pain in the ass, (especially the enclosure, at least for me), but given my above concerns, a DIY 12V supply for my Geshelli DAC is on my 'to do' list. I'll buy the Schottky diodes from Mouser, and the Belleson Regulator (link) direct from Belleson, as their regulator made great improvement to my Graham Slee phono stage over its 7818 regulator. Below is a link to some LPS reviews, at least one of which uses the Belleson regulator. Be prepared for sticker shock on these though, which is the other reason which makes DIY a lot more intriguing to me. Good luck.

i didn't know they were offering things like the Sparkos opamps, so thank you for that!

Just what I was looking for, actually. |
