Sorry, silver audio equipment is pretty aweful...
I'd take black anyday.
I agree though, the gold is quite attractive and there's still a few Yammie models that are gold.
My Marantz receiver is not quite ugly, but pretty close.
Technics had some receivers a few years back in that grey/brown colour.
I think black is so motif neutral that it sells better. And most of my equipment is black anyway so it matches.

I just saw some Sony brand speakers with bright neon yellow/green woofers and tweeters in them...yuck.
