Upon removal of Niagra 5000 and install of P15, imediate notice while the P15 was on, connected, but nothing playing, there was zero sound, buzz, emitting from the P15, that was huge for me.
Playing either stereo or MCH sound seemed improved, better bass and over all sound structure, however to be fair, there is likely placebo, that has been my experience when buying things audio, ask me in a month if I feel same way, but for now thumbs up on all things P15.
Now for the screens, three pictures self explanatory.
The largest difference of all is distortion in vs distortion out.
I know nothing about whether this makes a difference to a highly educated person, but for me, with screens showing me improvement and sound improvement, I think it was a good decision for me to purchase, other than that I am unable to be in a conversation about this subject. The last STATUS picture does fluctuate at about every other second.
There are other screens and you can make adjustments, but I don't want to experiment making adjustments when I don't fully understand, maybe later when I fully understand?
