Hi all, I am quite new both to this forum and as an audiophile. I just got my hands on a pair of FAD FI-BA-SS. Knowing that tips generally make a big difference on sound quality if not the sound character of the iems, I would like to know if it's worth it to replace the stock tips with Spinfit or any other type of ear tips? I have never used anything other than stock tips so it will be great if you can provide me any impression or opinion. Thanks a lot!
