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

pwerahera I have the same view as you express in your post.  I wanted to see if anyone on this forum could give me convincing argument to change my mind.  The cost of these power control units and cables is far to high for the benefit the purport to deliver.  Good quality surge protectors and a stable source of AC is all I need on that end.

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.

Carlsbad:  Your comments coincide with my beliefs.  I somehow could not wrap my head around how the quality of sound would be affected by the electric connection cables assuming they were adequate for the needed flow and fit will with no interferences.  My house current has always been adequate for the loads of my system.  My main concern is surge protection and I have accounted for that.  Looking at four figure prices for power regulators and cables had me puzzled as to how much they would affect the sound from my system.  Thank you.

Steve, Thank you for taking the time to post such an informative description on the subject of cables.  I buy into the contribution of high quality connecting cables between components up to a point of cost/benefit.  The value of a power supply unit costing 4 figures is questionable for me, given the stability and lack of interfering noise on my rural electric supply.  I am really curious about Lordmelton's suggestion to try HiFi Tuning gold plated silver fuses, I assume on my Threshold amp.  I wil explore that.  Thanks all.

Indeed. That is my conclusion.  I will invest in a new cartridge for my turntable.  I think the Koetsu has worn down.  That will make a hearable difference playing records. Thanks all who took the time and trouble to answer my question.
