could somebody help me out on the benefits of expensive phono and speaker cables?

Here’s a real life example. At the Tenor/Rockport exhibit in the Tuscany Hotel in Las Vegas in 2001, best of show that year at CES, the system consisted of Rockport Hyperion speakers ($100,000) that were biamped with four Tenor tube amps ($100,000 total), and Jena Labs Pathfinder and Shunyata cables (estimated cost of all cables $10,000). Thus the percentage cost of cables in that system was only 5%. Actually less than that since I didn’t include all the isolation stands (5), the CD player and the Audiokarma break-in device that was used to break in all cables. Or the cost of the huge 40x50 room to put it all in. Of course $10,000 for cables is nothing to sneeze at for most working stiffs.

Aahhh CHOO!                            

@geoffkait  but you can substitute out all the fancy power cables and it wouldn’t make any difference whatsoever. Then you could substitute out the interconnects for  Belden  and it might sound slightly different, but it might actually be a hair better.
