Back in the 80's I remember salesmen trying to convince audiophiles that the first generation CD players were the "ultimate" and totally superior to vinyl. But to realise the benefits that "superior" CD offered - it required another investment. A special very high cost isolation stand was required to remove the obvious harsh digital distortion that was caused by vibration.
This was of course all sales bunkum - but it extracted a lot of money from the gullible who did not realise the real issue was the CD player design and limitations of the medium.
From my perspective there is a hierarchy in audio systems - based on proven engineering principles: The system foundations are the amps, loudspeakers and of course the quality of cd/anologue sources. Room acoustics and personal hearing are also important factors.
Second comes the interconnects/speaker cables that we all agree can make or break the system.
At the third level, I believe good mains filtering produces audible improvements in a high-end system and I use one!
However, I personally have not detected any audible improvements in changing from good stock (Isotek) mains cables to very high cost esoteric alternatives.
Instead of spending big money on mains cables I suggest a "signal path component upgrade" may be more rewarding.
