Don’t go crazy, there only cables.
having some silver in the wire does boost the highs and sparkle a wee bit, compared to just above average cabling
those Groneberg rca’s are quite nice, as well.
I now use average Belden shielded rca ‘s from amp to preamp, they remedied the radio station tower 1.5 miles from my house, where as the audioquest did not.
There are a lot of 10$ words for cables, don’t get sucked in to spending too much $
try those Groneberg rca’s, they are shielded very well' and are a good snuggish fit on the pre and amp.
I like those cables, I also like my audioquest balanced pair. Haven’t used in a while.
anyway, get those cables home and use one on right Ch one on the left ch. , and switch back and forth for audible differences.
enjoy the auditions
