So in an effort to thin the proverbial herd, I'm come to a weird decision on which I'd like your input. My two primary IEMs are TF10s and W4s. If I use a 10 point scale, the TF10 is a hard 9 and the W4 is an 8.5. Since I'd like to sell one, the problem lies here: I'm not a big fan of the awkward TF10 shape and I'm considering a re-shell. Given the fact that I picked them up used for $150, a re-shell from InEarz will keep the total under $300. (For reference I got the W4s LNIB for $250). So, should I go through the hassle of re-shelling, taking into account that it may change the signature, and sell the W4s or should I hedge my bets and sell the TF10s and keep the W4s? Any thoughts or advice would be appreciated. EDIT: Something else I just considered would be sending the W4 to BTG to make it cable replaceable and then maybe an upgrade cable will improve the sig to overthrow the TF10?
