Need your expertise on reshelling. The problem with my old 535 which was just serviced due to driver degradation and warranty will be expiring soon. In future if it happens again, I'll need to pay a whopping $300 to replace per side. So I'm thinking of getting it reshell. Among this there were other reasons too, as when I use the IEM over a long period of time >6hrs, it's painful and the replacing waxed olives kinda irritating.
Currently, there is 1964, UM, stage 94, null audio and heir which I can contact from Singapore. At first I was intending to reshell +3 but many review say it kinda spoil the orginal quality so this idea is out.
It seems that only 2 companies(1964 & UM) does tuning after reshell so it would be as close as original sound stage & more balanced, does this matter?
So can I get some feedback on the above five companies on their reshell and sound quality after the reshell please?
Any good / bad experience are welcome.
