I have a few DVD-A discs and a few older universal players to play them. It is not worth the price you would pay for sure. A lot of releases were simply 24bit/48Khz. Why not just invest in high resolution downloads instead? You could actually create dvd-a discs on your laptop from the downloads using appropriate software. I used to do that a while back but then I just moved on to flac files stored on a HDD.
As for sound quality compared to sacd, it all depends on the original master and the remastering. IMHO, no point starting now, you are late to the dvd-audio party by a decade or so given that we have blu-ray audio and much higher resolution DSD downloads.
