I am the owner of a 38A and it's not $5000, you can get it new for about 950.00 (probably less now). The $5000.00 dollar model was the DV-10AX which only supported SACD in stereo, not multi channel. The 38A does also play MP3, though I can't imagine too many audiophiles use it for this. The 47 plays SACD as well as DVD Audio, Video and CD, so it suppports one more format. On the other hand I am told that the build quality is much lower with the 47 than the 38A. I've never matched the two sonically, so I'm not sure how they match up in that respect.
