Fact: there are far more SACDs available than DVD-As. There appear to be a lot more classical and jazz SACDs than DVD-As (but I can't confirm this). Fact: there are hybrid SACDs; there are no hybrid DVD-As yet (to my knowledge). Fact: DVD-A is undergoing a major marketing restructuring, presumably to save it from death. Fact: more small labels support SACD than DVD-A. Consensus: SACD is more of an audiophile format than DVD-A; DVD-A is more of a HT/MC format for consumers than DVD-A.
But ponder this fact: in tha past 30 days I've (gone kinda crazy and) purchased about 40 CDs. Three of these were SACDs, all albums I really like and already had on CD. Three out of 40; there isn't much else out there that interests me that's available in SACD that I don't already have. I'm reducing my stake in SACD for the moment after realising most SACD players are mediocre redbook players and that a really good redbook player can sound virtually as good as SACD (something like the Resolution Audio Opus 21). I've got far too many CDs to accept mediocre redbook. To give credit, a few high-end SACD players can be remarkable in both formats. I'm also a strict two-channel guy so MC isn't important.
Based on the facts, and the experience, I chose SACD over DVD-A. In hindsight, I would probably have waited longer to jump into any high-rez format. Lots of redbook to enjoy on a good player.
