As you can see, some say yes and some say no. The only way you can come to any conclusion is to try it yourself. Personally I found that some power conditioners can adversely effect SQ and that spending big bucks on power cable is a waste of money. There are many cables around $100 that will do the job admirably.
Do power supply units/cables make a difference in sound quality?
My system is plugged in via a heavy duty power strip into a wall socket. (Horrors!). I have read many posts from folks who have invested $$$ in power supply units and cables. Before I take a deep dive into that, I'd like to hear from folks pro or con on this subject. My system consists of Magneplanar MG3rs, Nelson Pass Threshold 400 amp, Conrad Johnson recent premier preamp, Oracle TT with Koetsu Black, Bluos Node streamer, Classe Audio CDP-102 CD Player. I am quite happy with the sound from all sources. So am I in for another four figure expense with power supply? I appreciate the experience of this forum's members.
