I recently bought HD800 headphones along with Icon audio HP8 valve amp.
While using this combo in my family home along with Micromega MyDAC (not USB powered) and iMac everything was fine.
Upon moving the setup in my flat I noticed noise started appearing when DAC is powered and connected to laptop or iMac as well.
What would be the best solution for this?
New power supply for DAC, good USB cable, USB filters like JitterBug, regen, Wyrd etc ?
Any help would be appreciated!
