How good does my system have to be to realize an improvement with cables?

Spend whatever you want on cables but they are system dependent. For laughs I put a pair of ten thousand dollar interconnects between an old receiver and CD player (used them also because they were handy) and the results were better than I anticipated.

A Speaker Cable is a good starting place to pick up on how a Cable Interface can impact on the SQ of a System.

A Tighter/looser Base and Mid’-Range Projection / Suppression are reasonably easy to detect as Cables are exchanged.

This is a good starting place to attune the ear, as this where the most immediate changes are likely to be detected.

The other good side to using speaker Cables is that there are plenty options at fair money, and a cheap option can easily impress over a much more expensive option.

I have in the past swapped out carefully selected $20 per metre Cables for Mapleshade Double Helix Clearview Cables, and very recently, replaced the Mapleshade Cables with a Acoustic Revive PC CCC Cable which is a much lesser price and surpasses the M’shades as an Interface.

Other Cable comparisons are not such an affordable option, and can get quite expensive, seeking out Cables with a Return Period included in a sale might be beneficial, to increase the experiences.

To get the idea of the M'shades performance, I loaned them out, where they were used at a Speaker Cable Bake Off, with a range of Silver and Copper Cables present at a cost of up to £500 per metre.

These were used on an EAR Valve Amp > Quad ESL System.

The M'shades were selected as Joint Top Performers along with a Silver Cable.

I was very pleased to learn of this, as it was testimony to my choice made from previous investigations.

The organiser of the event only deselected the M'shades as they would be an Import to the UK, and they wanted to Support UK Business.

The Silver Cables were chosen from the Brand True Silver, it is not too difficult to check out their prices.  

Call TheCableCompany and borrow some cables.

Any high resolution system will improve with great cables.

@ebm 

I appreciate that but at what point does a system become classified as "high resolution"?  If I think my system is only a "mid resolution" system will simply adding cables bump it up a notch to "entry-hi"?

What are the criteria I can use to classify where my system is on the spectrum and that cables are the component holding me back?
