DB: glad to hear about the 2900. some thoughts:

is your avia disc a dvd-a or dvd test disc? if it's dvd, you may have to be in a digital mode in the 950 to hear the sweep. also, i don't think any player has BM for sacd (i could be wrong).

if your set-up disc has phase tests, see if your phase is doing a 180 degree shift when in 6 channel bypass mode.

calibrate your sub's level to EXACTLY the level of the other speakers...don't run the sub 'hot'.

i know that you know the following, but as dvd-a/sacd 'places' insruments in any particular point in the 'circle', sometimes for the entire cut, placement, angle, phase and levels are more critical than for movie sound.

tweak your speaker placement with a tape measure to place them as close to equal distance from the listening position as possible and apart (FL-to-C the same as FR-C, etc.).

tweak the angle of toe-in of the satellites to be the same in each surround and the same in each front main (i've found that moving one surround to toe-in an inch more brought the rear sound to perfect, for an example).

if your sub is in phase with your satellites, your placement is as correct as possible, your levels are calibrated and there are no cascading filters between your 2900 and the 950...it will sound very, very good.

when you get your 2nd sub, let me know. it's relatively simple to have perfect BM in dvd-a/sacd with 2 subs (you'll noticeably hear the difference and that 'bloat' will be gone)

your set-up sounds great...i'm jealous. tell me more about the 2900 when you have the bugs worked out.

more must-have sacd multi-channel:

1. james taylor 'hourglass'

2. spyro gyra 'in modern times' (this is the best mixed multi-channel disc i've heard yet, by a studio called Heads Up.)

3. diana krall 'when i look in your eyes' (Will turned me on to her, though he mentioned the cd version. get the hybrid multi-channel sacd, it has both versions encoded (2-ch cd and multi-channel sacd).

also, thanks for the update.
