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.

My tubes are 8 years old so it is possible that this has something to do with it. I may try using the D1100 as my pre amp. / DAC.
