I know exactly what you mean Dan. I have the BiA album in 5-6 formats (CD, SACD, DVD, Vinyl, XRCD and I think I also have it on a cassette) and some of the editions I have multiple times (vinyl from many countries around the globe, CDs new and old). I guess you have to heva a very expensive hi-end system and ears to match to listen to the differences, although from format to format and country there are some.
