It's quite likely SACD (or to a lesser extent DVD-A) will never find its niche with audiophiles because we all prefer vinyl, given the choice. However, SACD is definitely going in the right direction because:
(a) it's less of a compromise than CD sound,
(b) music recorded on DSD today (it could well be the medium of choice for the majority of studios) transfers naturally to the SACD format which means less to go wrong from instrument to disc and
(c) SACD shares a lot of what makes CD so popular: convenient size and durability.
Technically SACD has a lot going for it but its financial sense is less clear and it may well die from underinvestment.
