Hi Manuel,
The wire upgrade is the reference wiring. The condition is very good, no issues what-so-ever. I used it with my VPI Prime for about a year until I upgraged my TT to the Spiral Groove SG 2.2. The XLR junction box with some good XLR phono cables made a marked improvement to the sound quality.
I’m pretty certain it will fit on your Classic, but would be good to double check. The XLR junction box is the same depth, but a little wider than the RCA junction box. I’d like to get $300 for it.
Best, Larry
