Unplated copper spades/banana

I use Viborg copper spades and I can hear absolutely no differences from the previous connectors.  None.  Zero.  But, I do like their look.

As I read all these posts, I can't help but wonder what the systems of the people posting are like.  If your system cost less than $10k, I'd be surprised if it would reveal differences in plating type or plated versus unplated.

I also wonder about the listening skills of those posting.  Do they have have a playlist of "system test" tracks that collectively reveal the major aspects of sound quality?  Do they have a disciplined approach to listening?

I'd like to hear from someone with a $250k+ system who is a highly skilled listener.

For what it’s worth, coming from Monoprice 12g wire with Nakamichi bananas, I went with the Viborg pure copper banana plugs on Furutech FS-A36 12g speaker cable. I tried one speaker with the Nakamichi & the other with the Viborg both treated with Stabilant & the Viborg & the OCC Copper made a HUGE difference. And I thought my system sounded good before the change.

I often wonder that too.  Mine is posted, as is yours, and it is nice to have that perspective about the system a poster is listening to, in order to help understand how they developed their viewpoint. 

Why do we need to have high skills to listen or enjoyed music?
