I wasn't running it full range, I am using it in a quad-monoblock config. Active XO/EQ on the LF; I did it that way because the SQ increases when you do (at least for the B&W's it does). Keeps the LF from robbing power from the tweeter. Must be some sort of inductive/reactive/resistive modulation feedback from bass woofers messing with tweeter reproduction; best to have separate channels for HF/LF and then that doesn't occur. Also I'm house-curve boosting the LF by a few db's, so it needs its own channel to do that.
Most people wouldn't notice such a difference, but I do. That's what happens when you listen to your gear 64 hours a week (give or take) for years on end, you get to know it very very well; good and bad.
If you notice that your system sounds better late at night than it does during the day, it is likely because your DAC and amps aren't truly transparent (enough).
With the Yamaha AVR, Rotel Pre/Pro and Emo Pre/Pro I used to use, it would have this problem.
This is completely solved by the Oppo 105 feed by a PPP, and a 10k clone quad-monoblock amp config, it sounds good at all times from the moment it actives, and it doesn't change tone once it "warms up" either.
Not sure what it going on there, but something is going on there.
-My 2 cents anyways.
