Great choice! I think the Black Label and the Andromeda have excellent synergy. Makes them sound very airy, with zero hiss and a nice full sound that rarely needs XBass on. The knocking is annoying indeed, but it's the price to pay for having solid metal shells. BAs are usually fragile, but that little knocking isn't a problem. Might scratch the green paint a bit with time. To be honest, I don't think you can avoid the paint chipping with time (at least at the edges) and the bads will be an inconvenience. What I do is try to separate them when I put them in the case. The original case squashes them together, but with the side flaps removed, there's a lot more space (easier to store, no rubbing together). I posted that mod a few pages ago. Never noticed that, but all ears are different, plus tips and insertion also change things. In my case the Andromeda are quite comfortable, at least as comfortable as something "round and smooth" like the Shure SE846. Can't help here. I like Spiral Dots, but not so much Spinfits. Silicone didn't work well with the Andromeda for me, especially with some loss of low frequencies. I get a fuller sound and more comfort with Comply TX-400 (Or TSX). Also, given how huge that pig-nozzle of the Andromeda is, I prefer to have a thin mesh like Comply's Waxguard in the way to avoid debris getting inside. The effect on sound is imperceptible to me.
