Two weeks into the new surroundings, I couldn't be more pleased with how everything sounds :-)
I dedicated the longest section of wall space (16') in our 29' x 16' great room to the HT rig and it fit wonderfully. Just enough elbow room for the Motion 40s and the PC13ultra sub. And as luck would have it, Audyssey gave me a nice and symmetrical -5.5dB for all 3 front (LCR) channels.
The components fit nicely on an end table, with the Emotive XPA-3 underneath, resting upon the (since exchanged) PB2000 sub platform I was hanging onto for just the right circumstance.
The XPA-3 appears to have added the power that the Motion 40s and 30 deserve ... Especially at lower listening levels, the speakers have come alive, so to speak. Kick drums have a profound impact, and vocals are crystal clear, whether it's TV or movie dialogue, or an opera aria.
Orchestral instrumentation seems more distinct and separated now, providing an even greater soundstage ... my opera and classical music Blu-rays sound better than ever and the bass-heavy chillstep for casual listening appears more alive and detailed.
Not sure I needed to upgrade my my PC12plus to the PC13ultra, but I did and there's plenty of low end sub frequencies throughout the entire one-floor abode. I can only assume that the ultra driver has added to an even more precise bottom two octaves.
So between the XPA-3 addition and the sub upgrade, power will never be an issue ... the added detail and nuance that these to most recent purchases have provided have elevated my 5.1 HT rig to a whole new level.
