Boss, what is the outcome from your test of SR-60i and impedance adapter (what ohm you use?) . Any promising effect in SQ.

Oo, ok. Don't test on your Atrio M5?

Haha. Should recommend this to bro yuan415. He's been complaining bout his ES7 lack of bass

Perhaps sometimes later maybe I'll commit to impedance adapter test. Don't have any expectation, just curios though

I've just tested 75 ohm impedance adapter for a few days.
Test subject:
phone - silver bullet, piano forte II
amp - 3move
The observation:
-Slight addition in bass department. Both silver bullet & piano forte II is not a bass phone, so its ok.
-Clean sound, i like
The price to pay for these: clipping the other part very much, high, middle, you name it. Sound very weird. Don't like it

Lesson I've learned:
-Dynamic and 75 ohm impedance adapter not good paired. 75 ohm is high. May be good if choose lower impedance? Don't know. maybe yes.
-Do not pair with bass phone, the bass will become too overwhelming (tunertoobe)
-75 ohm is good with high clarity BA IEM, originally intended for er4p.

yupp, more or less the same plug. Got mine from ebay. Locally, you can order from more2teayap.

hm3 made a good pair with 39 ohm impedance adapter. 75 ohm is no good.
