Do power supply units/cables make a difference in sound quality?

We've been through all this dozens of times in the last year.

Clearthinker has his head screwed on properly.

I'm not with the dreamers who think they can hear differences in passive well designed mains cable and even fuses but they will never agree with me nor submit to blind tests so it can be proved they are not simply experiencing confirmation bias.  Until they do, this will run and run, wasting everyone's time.  They should shut up.

But system interconnects can make small differences and active conditioners can certainly clean away unwanted noise on the line if your power supply suffers from that.

i think you're lying))) - you have good components and you probably use good cables...

A good cable is better than a bad one

Seriously?  Did the OP bother to search previous threads before resurrecting this old horse of a topic?

I think the OP wanted confirmation that he wouldn't hear a difference when adding power supply treatment.

His only interaction was with fellow non-believers. This thread was a waste of time.

Oh forgive me for being new to this forum and asking a question some of you are tired of answering.  Fortunately, I did get useful answers which led me to conclude my money is better spent on getting a new cartridge than it is with power supply equipment.  I am grateful to those who took the time and effort to answer my question, pro or con.  The thread was far from a waste of time to me, but no one forces you to read it.  Anyone with 4,893 posts must be very knowledgable indeed.
