hi there folks,
i've been using ER4p, with custom moldings, for many years now, with either an RSA predator or PicoSlim amp.
my big issue is the terrible microphonics of the etymotics and i've been thinking of getting new cabling (custom, or adapters for westone, etc)
but now I'm wondering if i would be better off spending my money on something like the CTM-200.
can anyone comment on the sound difference i would expect from the CTM-200 vs. the ER4p (when driven by an amp per above)?]
