I also have 2 sets of the 846 with original cables and have never had any problems other than discoloration due to copper oxidation which doesn't affect the sound. I too have the andromeda and find it very impressive though it doesn't have 846 bass. The 846 has always been my ultimate go-to. I think you can't go wrong trying again. To OP : I know you said you're not interested in more expensive CA iems, but I just recently got hold of the Solaris, and the sound is amazing. Imagine an 846 with dynamic driver bass, solid mids, and holographic highs. Because of the size, I can't use it, though, where I might use the 846, (say, going to sleep).
