SACD availability

SACD discs are mostly classical and jazz but there's still many older rock discs available. I think your best bet is to get a universal player that will play everything including DVDA and maybe Bluray and you'll have all formats covered for a while.

If you are primarily a classical and jazz listener there is plenty of music out there on SACD as well as new releases coming out. IMO I would not consider a player without SACD capability. But I listening primarily to classical and jazz so I have no problem finding music to purchase. And as Elizabeth points out it appears that only the small / medium size labels are supporting it.
