little milton...FWIW, there is considerable audiophile interest in DVD-A if you look outside the USA. The DVD-A protocol permits great flexibility in how the data space on the disc is allocated. So, for example, we have the MMG label using what they call a 2+2+2 multichannel speaker configuration instead of 5.1. If super stereo is your objective you can have 192 KHz sampling instead of 96 KHz. There is much more oportunity to tweek DVD-A than SACD, and tweeking is an audiophile thing to do.
IMHO...Disc mastering and playback equipment is by far the most important factor for all formats,DVD-A, SACD, and CD. Some DVD-A and some SACD are worse than the best CDs. However, the best DVD-A and the best SACD can't be matched by a CD. As to SACD vs DVD-A...it's too close to call. And who cares? Enjoy both.
