I was just wondering if anybody here would be willing to buy someone's
custom built amp off the web,without being able to hear it ?

I might pay up to a dollar, if the shipping was free. But only if I was
feeling particularly loose with my money that day.

Um, no. With one (1) exception: Patrick Turner of Australia writes all
the right things in all the right places, and those of his suggestions
I have followed have been exactly as represented, or better.

Otherwise, I would much rather either restore/modify existing devices
or build my own. I know what I will get for my efforts, I learn a
little bit in the process at least, and it is incredibly much less
expensive.

It depends on the design. Something which mated Tripath or AKSA
modules to appropriate sized heat sinks and power supplies would be
fine. A good design (Nelson Pass, Douglas Self) built on commercial
circuit boards (good layout) would be fine. A well implemented
application note (The National Semiconductor bridged/parallel LM3886
designs) would be fine.

Otherwise I'd worry about about amplifier stability (I don't want to
cook my tweeters with an RF oscillation) and noise.

Used mid-fi amps known to have sufficient heat sinking and stability
are so cheap there wouldn't be a good reason to in most cases.
