I don't have any experience with SACD but I do have a DVD-A player and love it. Unfortunately, I don't think either format will make it. I think they will be eclipsed by some form of "E-Music" like MP3 or something web based that can be downloaded to a hard drive. It's like APS film, APS has advantages over 35mm for most consumers and it should have been a hit for the average consumer but digital cameras came into the mix and now APS is fading fast as will 35mm in the near future. DVD-A and SACD are great formats that offer superior sound in most cases but it's come to late and the avg. consumer which probably makes up 99% of the market does not care to have the "best" sound but rather the "convenient" sound. I give these formats another year or two and they will fade.
