Holy Frickin' Flashback.....Sweetspot Nirvana. Now I see what all the fuss is about.
I had this on Q8 way back when and remembered it as being a favorite. I've also had this on DVDA for a couple years now and I have always thought it was pretty good, but left still wanting. Based on the QQ recommendations I finally ordered the SACD (large price tag and all).
Poured myself a second glass of wine and put this one in. Suddenly I was 17 again with the familiar Quad mix I had come to love. What a difference these two mixes provide. The DVDA mix is centered more to the front, whereas the SACD Quad mix has the listener smack in the middle of the band. The SACD has more of a raw / jammin' sound, which is what attracted me to this music in the first place. "Smoke On The Water" seems tame on the DVDA but really jumps to life on the SACD.
I like the extras the DVDA provides with on screen videos, lyrics, and stills, but for sound,the SACD wins hands down. I agree with Bidkat that some of the old Quad mixes were not all that, but some were stunning and very well done, like this one. It gets a 10.
So if you haven't bought either one yet. Trust me, and get the SACD!
