Power cable

As an avowed music and hi-fi enthusiast from a very early age, over several decades I've tried lots of different power cords (and interconnects), ending up with those made by Abbey Road/Studio Connections (not the very top of their range, but far from inexpensive).

After all these years, my conclusion is that expensive cables simply aren't worth what they cost relative to the differences they make.  Just about any good quality power cord using thick multi-stranded (or perhaps just 13A single core) copper wire is as good as you need.  I've found the same with analogue interconnects, both SE and balanced.  Those made by Van Damme are reasonably priced and as good as (almost) any others I've heard, the sole exception being a pair of stupefyingly expensive Crystal Cables that I was able to borrow for a week or two.  They really did make a noticeable difference but their price is strictly in the category of If you have to ask...  For what a 1m pair of those cost, you could buy an entirely respectable hi-fi system.

Perhaps surprisingly, the most easily discernible and critical differences are those imparted by CD transport to D:AC cables.  I bought an Abbey Road one of those (not cheap either, even pre-owned) but (admittedly narrowly) prefer one of unknown provenance supplied to me FOC by a well known and highly regarded designer/manufacturer of loudspeakers.

But, for all that, there is a large body of hi-fi buffs who do seem to think that fancy cables are worth buying,  All I offer here are my own conclusions.
