future of 2 channel CD sound

We have it! It is called SACD.

There may be a new high definition audio format on the horizon, but I doubt the software will be sold in stores. I see no future in a high definition silver disc, that already was tried and failed (commercially). A high definition music server, as Seasoned mentions, is a much higher probability, IMHO.

I've done every version of redbook
from 'regular old' to 'remastered' to 'remastered from original
source' to 'remastered from original source by Mobile Fidelity';
to XRCD, XRCD2, XRCD24, and K2, sometime remastered
from original source, sometimes not.
IMHO it's 99% about the care taken with the recording, mastering, etc,
not the format named on the jewel case.
I have 'regular old' CDs that rival the latest-greatest K2s,
and SACDs and DVD-As.

But of course we all have to decide for ourselves.

FWIW, another take on it all ...

If there is, it will be on a DVD so as to provide storage space for the extra data. Or it will come as an internet download as internet bandwidth increases.

I agree with Michaelct - the range of quality on redbook CD is so huge that, for me, it's 99% about the way the recording / mastering is done, and 1% about the format. I think that's one of many reasons why higher-rez formats never took hold.
