you might be a little wide of the mark with that assumption ben, for instance just because RA sells cables doesn't mean he has any more expeirence of them than say Zanash does.

and it we accept that cables don't do anything, then all his experience is worth nothing, infact it worth less than nothing because he's potentially been lying to us all this time about any of the differneces in cables.

the only way forward is to test them,no tricks double blind.

asking people pick a particular cable out of  a batch time after time might be a step too far for our audio memory.

but asking people to chooose their favourite from the same three cables played in different sequences, seems to be within the realms of possibility.

at least it would show correlation,and maybe indicate a differnece betwen peoples abilities.
