I was using Stage Right cables, which are good cables however they only have singe shielding. I bought the Monoliths for their double shielding and use them for 2ch audio which you will see from the photos.
The connectivity is good, the connection is good, and IMO you can't have enough shielding.
Definitely will be buying more of these. Very well constructed. As for how they sound, I have not compared them to any other XLR or RCA cable as I am using them on a new system but there's no dropouts or any issues whatsoever after a week of use. A coat hanger can transmit sound signal as well as any high priced cable but for this price, you are getting a cable that is designed to last and not experience wire breaks which is what you should look for in a good cable.
I have a pair of these Monolith cables connected between my Rotel RC1570 pre and a pair of Emotiva UPA1 amps. I can't say I hear a difference between these and the unbalanced connections I was using previously, but I don't care, they look great, seem to be very well constructed and fit perfectly.
Am quite impressed with these cables. Connectors are much better made than the plastic ones. Very secure fit and excellent transition to the cables. Only minor nitpick is they arrived with the cable covering - some type of fabric - had a couple snags. No effect on function of course but for the price would have been nice to be perfect. Functionally these workgreat.
I bought these XLRs not expecting much by way of improved sound over what i currently have which they cost 4x the monoliths..and wow i was pleasantly surprised how much bigger my sound stage got and how much quieter my floor noise became ..iam throughly enjoying these new monolith offerings ..already put in a order for 4 more before the price goes up..thanks monoprice..
