Remember, these things have no speaker protection. It is one thing to crank them out in a controlled manufacturing environment, but from an unknown builder on Ebay? If I am working without a net, I want to pack my own parachute. Or at least to know a company would be standing behind the work. My board version had an intermittent connection on V+ on a channel that would have fried my good speakers.
Maybe someone should e-mail him and ask how that amp would sound with their $50,000.00+ JMLab Grand Eutopia speakers....
I believe somebody already tested what happens, if one rail colapses on GC. Supposedly there is no danger in that:

Personally, I don't think this is such a bad deal (providing he uses good parts and spent enough time on voicing the amp).
What I see strange about that setup is that there is only one DC output socket (on PS) and there are two sockets on the amp, wile cable clearly doesn't have a splitter. Also you can notice 3 pins for DC connection, which means that he's running common ground for both rails, which is not the best choice. Binding posts seem to be cheap Chinese variety. But chassis looks nice, although footing could be incorporated better. If this is milled out of solid aluminum block, you should know that it's worth at least $150 in materials and labour. So another $350 for the rest, isn't such a big rip off.

By the strong reaction, I wouldn't bet against you.

I think so too. You never know what length this guy / gal may have gone to perfect his gainclone? It could have been aged for years in a cold, dark, moisture-control'd cave in the Amazon, and I heard gainclones treated that way sound absolutely clear in the high-end, without being fragile.
Whatever that means,
Re: Re: Ebay....
That's the moral of the story. Some people want to instill the notion that somehow if you use exotic (high-priced) parts, your gainclone will sound great.
The problem is that what parts to use depends on what forum you are, whom the speaker is, and the phase of the moon.
Gainclones are gainclones are gainclones, and they just sound like every other decent amp (if put together decently). the "mysteries" and the efforts to mystify gainclones do nothing but fuel commercialization of such a wonderful products.
And this latest auction is an epic example of that.
Not that commercialization is bad.

That would be quite interesting approach and understandable necessary cost reduction if the amp sells at $500. You save on cable length in that way
I would rather see it as a provision for a dual PS, if somebody wants to upgrade later. Of course some switching inside the amp would be required.

I would say so. One forum member tried to calculate some parts included in such creation here: http://www.diyaudio.com/forums/showthread.php?s=&threadid=9112&perpage=15&highlight=&pagenumber=60 Check post #895
This is of course a rough estimate, that doesn't include any chassis parts and the exact components used, but can give you some idea of what it takes.

Well tis one ugly little sucker! I've built 3 Gain Clones with various differences, I sold the first 2 although for a bargain $300. I'll no doubt attempt to sell my current GC if the next version is better, I'm actually planning to build at least 3 more to try out various components ie Elna Silmics (yes I have found some) Blackgate NX in Super E configuration, Tantalum film Resistors and so on. My current GC are monoblocks with regulated supplies (well regulated capacitance multipliers I suppose). I don't think we should be so quick to condemn this guy (no its not me!).
As for E-Bay my chum got ripped off by a seller but E-Bay did Zilch! I'd never use them again. I prefer to sell to people I know and with a dem against whatever amp they use.
