yep, one good thing about headphones is they seem to keep their value very well, many used headphones (esp grado) seem to sell for only a few dollars less than the original price...
anyways, I personally don't like the megachangers, i don't find them as convenient as just about any other type of player. I'd think that it would be really hard to remember which position the discs are in, and if you want to listen to a CD somewhere else (car, discman), it'll be a real hassle.
But they are quite cheep these days, and i'd guess that the transport is reasonably good, comparable to other players in that price range. I really don't think its worth spending lots of money on a good transport until you already have a good DAC and can compare to see if there is really a difference. DACs with assymetric sampling rate converters or good jitter-resistant recievers shouldn't be affected too much by the quality of the transport.
And i'm sure that even the worst componant CDP will put out a MUCH cleaner signal than the best consumer soundcard....
Coolvj, i still think you should check out used CDPs, i think they will give you much better performance for that price...And the teac, are you talking about the minisystems? The teac componant CDPs look quite nice to me, are very compact (size of x-ray?), and have optical out...
