Mod works wonders to brighten up the very recessed e2c treble. Seems to liven up midrange tones too. Bass seems to resonate a little lower but its not as boomy and just a hair less impact in upper bass notes... but theres more impact to the lower octaves... A good thing IMHO. Bass notes resonate more, theres a bigger sense of "air" and acoustic space around bass notes, where before tones were just a heavy-weight thud. The thud is still there, its just at a slightly lower frequency, and theres just "more there" as the note decays.
Overall response is flatter across the spectrum, while still retaining the warm, foreward e2c mids... theyre just more detailed and dynamic now.
Noticeable step towards KSC75 realm, in terms of spectral balance and separation... but still not quite there. IMHO it still sounds compressed and lacks the spatial separation of either KSC75 or MS2. Soundstage is still not the e2cs strength.
Seems to isolate about the same.
Comfort is improved a little, as the body of the phone sits more snug to my ears. Also, tapering the tip of the tube helps reduce pressure exerted on the ear canal.
Ive never been a real fan of the e2c's signature... dull and somewhat boring IMHO... seldomly gets my foot tapping. Post-mod however, I caught my foot stomping to some Fogerty bluegrass lap steel and Eagles tunes.
Here are some pics...
Hope someone finds this useful.
