So how much difference in SQ are folks hearing with the P15 vs. P10?

New P20 ..... more details please?

The P20 has made a significant improvement in my system in terms of lowering the noise floor thereby letting more details be heard. Makes the system sound more natural, more life like. Dynamics have increased as well and are seemingly unrestrained even with a DS DAC, DMP, BHK Pre, a pair of BHK 300s and a pair of 12” subs (each with 1000 wpc rms class D amps) plugged into it. It runs cooler than my P10 did with the same equipment connected. And, I am only using a 15 amp circuit. Very happy …
