Unbalanced to balanced VPI junction box change?

I have an XLR junction box...no need to change from Valhalla (unless you want better sound - I had Nordost and now have Discovery...in MY system, it sounds much better). Just get the junction box and install it yourself ..easy to do.

Atmasphere.....I have a totally balanced system (all Ayre components) and can readily hear the difference in cables....

Standards, Schmandards, ....I'm a musician not a scientist. My system is DEAD quiet, and sounds like music....that's all I care about

Atmosphere...you're absolutely correct. I found that the high priced spread often is not as good as the lesser ones. I feel that there is no such thing as "The Absolute Sound". Yes, there are qualities that we appreciate being reproduced, but I've played in a number of venues....Alice Tulley sounds different than Carnegie which sounds different than Boston's Symphony Hall.... My violin sounds different in my practice room than in my living room just a few yards away. I dare say, I've never heard my violin the way my listeners hear it....my instrument is under my left ear. Even when I have a another violinist play my instrument as I step back to listen, her/his manipulation of my bow is different than my technique...and therefore sounds different. I have tried just about every brand of string on my instrument...yup, they all sound different, and sound different with the amount of hours you log on them. There is no right... What I try to do is construct my listening to what pleases me...that makes me smile, and be damned the specs.
