Audio Signal Run Through a Banana

Yesiam-a-pirate, just noticed your moniker. Are by chance 200 years too late?

Theo; I'm an over 40 victim of fate! 

Let your ears decide ,not anyone else , every ear hears a bit different ,we all have frequency loss from age ,and loud music or sounds through the years ,

I'm soon to be 71, with slight hearing loss in my right ear and a mid-fi / entry-level system. I can hear the difference between generic analog interconnects and somewhat elevated OFC copper/silver plated AQ interconnects on analog sources. I tried out some better quality digital cables and heard no difference. This is taking into account my age, hearing deficiencies and system level.

The majority of those connections looked to be copper wire with whatever alternative connected in the middle. Certainly the percentage of the copper vs other is a factor.  
 

Either way, I’ve never had really expensive cables, but I do have good cables that have made a difference, and I’m not giving them up anytime soon!
