Congrats...it's addicting....it (5.1 audio) in general challenges the theory that surrounds can be alsorans...I like my RBH bookies, but the change to the B&W 804 (my old mains) made a positive difference. I'm leaning strongly to a pair of BMRs for the rears when I pass the B&Ws on to my son....the RAAL is so different from the B&W tweeter, and the RB5i.
I've now played it 3 times, 2 in multi-ch...The 1st time around it was different hearing the surround mix...in a good way, but it took the second playing to really give me the appreciation.
DSOTM...I have this in SACD...in stereo, but maybe there is a multi-ch version as well.
Multi-ch hi res is a game changer...I never thought I would be saying that, but it's been said that's where the wow factor is in hi res music, and for the most part I agree.
