In reply to:
Can you recommend any good SACD's?
Note there's often a huge difference between artistic quality vs technical quality of the surround mix.
I have many SACD/DVD-A albums by great artists I like, but the surround mix isn't very good -- muddy, flat, etc.
By contrast the good ones are so spectacular, it's as if you're hearing it for the first time.
My recommendations:
Pink Floyd - Dark Side of the Moon (SACD)
Eagles - Hotel California (DVD-A)
Fleetwood Mac - Rumours (DVD-A)
Elton John - Goodbye Yellow Brick Road (SACD)
David Bowie - Ziggy Stardust (SACD)
Roxy Music - Avalon (SACD)
Dave Brubeck - Time Out (SACD)
Mike Oldfield - Tubular Bells (SACD)
There are several very well known albums by famous artists that (to me) have sub-par or downright poor surround mixes. In general these are older material so maybe it's a source quality issue. However that's not universally the case.
Re-mixing for surround isn't like a simple digital remaster. It requires a lot of manual artistic decision, and the skill of the mixing engineer can make or break the final product.
Less than stellar surround mixes (IMO):
Peter Frampton - Frampton Comes Alive (SACD)
The Who - Tommy (SACD)
Neil Young - Harvest (DVD-A)
Derek & the Dominoes - Layla
REM - Best of REM (DVD-A)
Beach Boys - Pet Sounds (DVD-A)
Fleetwood Mac - Say You Will (DVD-A)
