Rob you are 100% correct, the Tripoint Spartan lets you hear this clearly. Voltage regulation is not the answer as it will add compression and artifacts. Folks will not understand this without listening to your system. I hear the same effect in my own system.
Summer Power Woes
For the past month, I've found my system to be a little stale and uninvolving. The other week, it became apparent that the sound was significantly better in the early morning compared to the evening. This morning, we finally get a 'relatively' cool morning, and the sparkle is back.
Just a reminder to not judge or make critical comparisons during the summer when the temperature is over 100 and everyone's AC is going 24/7. Systems can be very dependent upon the quality of electricity, even when one takes many steps to minimize this effect. I am convinced the effect is quite clear under these extreme conditions. And, it is not just your own ACs on the power line, but everyone else's.
