To treat lifelessness sound, I recommend the following.
1. Bypass room correction (Audyssey), EQ, and DSP other than Stereo mode.
2. If you had a Denon or Marantz, I would suggest using Pure Direct 2.1 mode, but you don't.

3. If you don't already have nice subs, I highly recommend using 2 subs.
As I've said earlier, those Focal 826V are quite sensitive (91dB/2.83V/m). From a 3m (10ft) distance, you only need 11 watts per ch x 2ch to produce 95dB from 2 speakers combined. Adding subs will increase this total SPL from 95dB to about 105dB, which is damn loud to me.
