Hooked up my Surround Master yesterday (in 5.1 mode). Only had a couple hours to play with it, so listened to a lot of individual songs to get a feel for it. I agree with the general statements of most other folks. Results ranged from Good to Spectacular. Definitely the best surround processor I've heard. At its best some of the mixes sounded like solid discrete mixes. Like others, even when there weren't necessarily discrete sounds, I definitely heard a lot more depth & detail in some material. Here's some specifics:
Something - The Beatles: Lots of detail I hadn't heard before. The flanged guitar part is a lot more prominent throughout.
Voices - Russ Ballard: The opening synth is very cool. All over the place!
If She Knew What She Wants - The Bangles: Very close to discrete vocals with the leads in the Center and the answered group vocals in the rears
Somebody's Baby - Jackson Browne: Exposed a lot more guitar detail
Ten Years Gone - Led Zeppelin: Heard a few more bits & pieces of the Page guitar army that I hadn't heard before
Africa - Toto: Sounded like a pretty good discrete mix (I haven't heard the SACD). Revealed some acoustic guitar I hadn't previously noticed.
If You Leave Me Now - Chicago: Also sounded very close to discrete. Horns up front & acoustic guitars in rears
Calypso - John Denver: Orchestra was pulled to the rears
Fleetwood Mac - Rhiannon: Sounded as if it could have been on the Rumours SACD
Galileo - Indigo Girls: Heard some low background vocals I'd never noticed. Looking up the credits it appears they are Jackson Browne & David Crosby. I'd say they're worthy of bringing up in the mix...
Anyway, I'll report back as I play more. Busy tonight, so it will be at least Wed before I can go again! At any rate, Chucky & Co, great product!
