Yet, Barry, you actively seek not to on your own equipment, and to my knowledge have a preference for using equipment fitted with connectors used in professional applications...?
Take SMA connectors out of the equation. What about the likes of Cannons or XLRs (leaving aside the balanced thing), or whatever your favourite connectors and sockets are?
IMO, and I'm sure I've heard you say it before, these offer a more robust and reliable connection than RCAs, which you're on record as saying you consider as inferior in comprison, in that respect.
*That* is the point I was making earlier to Oliver, which Jez came in and stamped on with his big size 12s, not anything to do with 'sonics'.....
Although, that aside, my suspicion is that they *could* also improve SQ, due to (as I understand it) them having a greater contact area, and which may result in superior signal integrity.
