I just learned a painful lesson with my Neutrik patchbays and monster cables...I had the NYS-SPP loaded as the bottom item in a slanted rack (an MAP turret rack) and had screwed in only the top screws (not also the bottom screws). The cables contacted the bottom of the rack in just the right way, causing them to angle enough to disconnect from either the tip or the sleeve of the bottom-most jack, leading to a few dB drop in my balance signals. I took apart my rack, found that the cables were properly seated, but could be forced around so that they weren't properly seated, and pondered how to fix the problem. After 15 minutes, it occured to me that by screwing in the bottom screws it would tilt the unit ever so slightly, anling the cables off the bottom of the rack, and the problem was solved. Now I know why the pros trust only solder on their patchbays...
