I purchased a pair of FiiO RE-SE1 cables for my Shure SE215's and I am delighted with them. There is an audible improvement over the stock cables in overall frequency response, presence, and clarity, well worth the asking price. No connector problems so far, either, as I had with the original Shure cables when first purchased. My interest in my SE215's is rekindled!
Just got mine today. Totally agree with you man! It has once again brought new life into my se215. Was initially using the 535 sadly never had the chance to try this cables on it as i had sold it to get the SE846. Hope the cables pairs well with it when it comes next week that is if i get mine within the first batch. New life was added to it when i paired it with the AK120 now with the new cables its just amazing.
In terms of sound. The RC-SE1 improves the sound stage and the bass is definitely much tighter than original cables. (Not too sure if the audible difference is due to the fact the the originals are old and has oxidised as it has turned green in certain parts) So someone with new original cables should try to make the comparison too.
Definitely a worthy replacement cable to get. Considering the fact that replacement for original cables are just so damn ex.
