I build cables out of 6N UPOCC silver for people on request for people with the customs these days. It's not just cryo'ed but the purity is definitely up there with both of those. I'm rocking it on my Grados, UE's, and my Sennheiser HD-580's right now. Night and day difference. A lot of people who are afraid of blowing 2-300 bucks on cables are being completely logical but it does make quite a difference.
Silver cables don't cost that much to build if you look in the DIY section, they're just expensive when youre cryo-ing them and manufacturing them in very complex ways especially in the US.
I completely respect ALO's offerings though. They sold me a recabled SR-225 back in the day with their OFC copper and I'm telling you these cans stacked up to the RS-2 ezpz.
Haven't had any experiences in the 2 years I've been using silver with breakages, it all depends on your manufacturing process.
I don't have any preferences over silver or copper considering I haven't used OFC before. I just know silver is more conductive than OFC no matter how pure the copper is.
