RELAXIN' WITH THE MILES DAVIS QUINTET HiRes 88/24

This album is very popular and like other modern jazz album played with acoustic instruments, The Sound quality of HiRes edition is superior quality than that of CD.
According to the booklet in PDF file, the source sound mastering came from SACD edition released in 2004, mastered by Joe Tarantino.
I purchased this one @ HDTracks, but now not available, maybe this one was available only limited time.
