28C, AFAIK, is discontinued. Supposedly they are working on KPS version of
SACD player. ( Krell is vague about its lanuch date, however )
It's an excellent player if you like your music presented big and bold
with good pacing.
I would think, however, this player needs some consideration with
ancilaries. (it's a better match with a system with a warmish slant )
Otherwise, it can sound rather stark.
Why Krell players difficult to sell?
I dunno. Personaly I found Krell digital excellent. But they do have
a strong house sound and not all audiphlies *approve* of it.
