Yeah. People sell for various reasons. As for why no one buys so far, well, they are still very expensive or unreachable for many. Can you do SS separates for $10k that would outperform Diablo 300 ? I am not at all sure unless the equipment is quite old. Might depend on your system and taste, of course. There is old Gryphon preamp on usedaudiomart from Canada for about US $2500, so..if you can find some old Gryphon power amp for, say, $6k-$7k, then this might out perform Diablo 300. Other than Gryphon brand, well maybe some old Nagra and other Swiss electronics, maybe.
