After 10+ years, I finally got around to opening this DualDisc. It's one of those funky original issue DualDisc Jewel Cases with the push-button opening deal, and of course with my luck, one of the pins was broken so the door fell right off.
Anyway, I've been meaning to listen to this for years and finally did. It's not too bad. I agree with the thoughts of the posters above, the 5.1 is not adventurous, but it's pretty old material. Sony should be commended for getting this out, but scolded and reprimanded for not releasing this as an SACD. It's an old argument - "You want the surround, you take what we give you". I would have to guess that this release was created to spotlight the DualDisc format, so that's what it is. Take it or leave it.
Anyway, after listening to it once through I got it ripped to the PC and found that I liked it a bit better with the rears jacked up about 2.2dB. It filled out the soundstage a bit better to my ancient ears.
I added jewel box scans, front and back, to Bob's original post #1 above for archival purposes.
For those who like wav forms, here's "Ain't No Sunshine". (For those who hate wav forms and complain "We don't listen to a jpg", then please ignore it)
(NOTE: This wav form jpg shows the audio AFTER I jacked up the rears 2.2dB.
