David.......Is your Aurender N100H music server powered by your PS Audio Power Plant Premier? If I remember correctly, you have the N100H installed in the built in bookcase opposite where your audio gear is installed. I assume your Power Plant Premier powers the audio gear in the case on the right, but I also assume the Aurender N100H is not being powered by the PPP. If this is the case, it may be that at certain times of the day there is more harmonic distortion on your house AC power that the N100H is subject to. At other times, perhaps late in the evenings when there is less load on the grid, there is less harmonic distortion on the AC power, and this allows the N100H to sound better. I am only speculating, but if the Aurender N100H music server is not being fed with clean power from the PPP, that may have some impact on system performance and may contribute to what you are experiencing.
Another possibility may be the tubes in your C2300 preamplifier. Perhaps the line stage tubes need to be replaced. It may be time for a new pair of Gold Lion 12AX7 / B759 / ECC83 gold pin tubes.
