i own one, but it's been broken for a few years now, so i don't want to make a sonic judgement right now. if it is perhaps becoming flavour of the month, maybe i should get it repaired!
there's something wrong with the motor or the laser pickup, it would make clicking noises when i try to play a disc, and it would not pick up the first track until i give it a hearty strong whack. i tried to play with it the other day and this method isn't working anymore.
anyway... as far as i remember, it was a really good player. if compared to the redbook vintage PCDPs though (D-777, D-E905, D-555, D-515, etc) i dunno how it compares.
hey pappucho, i see you have the aiwa HP-J7! i used to have two pairs, but sadly they've been gone for a long time. as i remember, they used to amaze me with the sound quality coming out of these earbuds. i used to use them with my D-321 actually, and i remember amazing detail, and gobs of bass extension without sounding bloated. can you comment on the J7's as i haven't heard them in many years.
if you're thinking of selling them, PLEASE PLEASE PLEASE PM ME!
