Got my CDs through and X-Ray Vision is fixed!
Unfortunately, "In A Silent Way" still scares the crap out of me on start-up in as it leaps at the listener in a slightly ironic non-silent way, especially after the long deep droning fadeout of "Car Crash Flashback V2".
That said, I agree with Brian that the sound is vastly improved over the original release. There's a plethora of little nuances I hadn't noticed before such as the fadeout vocal harmony on X-Ray Vision. Also, the instrumentation over the vocal section of "And The World Slides Sideways" seems less harsh with some increased bass. This definitely makes for a more enjoyable listening experience.
Even if you have the previous releases AND the Drive EP, I would definitely recommend adding these deluxe editions to your collection. If you don't then no moaning in a few years when you purchase META56, and realise there's a gap right in the middle of your collection where META 27 & 28 should sit!
