Not dissing you, Mr Bennett, merely raising an eyebrow. The good folk at Naim also believe that their CDPs sound better with the display switched off, and some of the Naim forum members say that you should mute the record bank of switches on the preamp for a lift in performance. This way madness lies.

Naim ARE in the business of after market cables and they are not cheap - new Burndy being a not inconsiderable £250 - for no return in terms of improved sound.

I think different cables do sound different - but this is a separate issue from that of directionality. Nordost, for example, sound worse the more expensive they are.
