Is it me or new audio gear is too perfect and give ear fatigue?

in my experience, harsh or bright systems are the result of:

1. noisy power supply

2. noisy networks (for digital)

The solutions are:

1. A mains power conditioner (PSM 156 is a great option) or mains regenerator if affordable.

2. An audiophile network switch (Bonn 8) with Linear Power Supply

3. Isolate the DAC from the network switch with a renderer (Antipodes EX)

4. Reclocking the digital signal (etherRegen)

5. Only use hard wired connections to

the DAC and avoid optical. 

5. Better power cables with after market fuses.

Ghod luck! 

....and clean the speaker cable contacts!
