As an early impression: amazing build quality, snappy connectors with a perfect fit, soft cable shield (no springy effect), cable feels strong, goes over you ears without a need for ear hook guides and stays around your ear thanks to a chin slider, hardly any microphonics effect. Sound quality - DEFINITE improvement! But I would consider it more appropriate for IM03 rather than IM50. With IM03 (using UE900 tips) the sound gets brighter, like a veil lifted off (and IM03 with a stock cable is great to begin with), you hear more definition and details in sound across the entire frequency range. The change is not just subtle, but actually noticeable. But improvement with IM50 (using hybrid tips) wasn't as tolerable for my taste because of a very simple reason - overwhelming bass. IM50 has enhanced bass to begin with, but now it's borderline basshead quantity. You get the same enhanced details but sub-bass became a little too much for me which took away focus from upper mids. Still well controlled bass without spilling over, but just a bit too overpowering.
Will do more listening and some burn in (from my experience, cable goes through some burn in settling as well), and then will post my final thoughts about it.
Just to add, since it was mentioned to check polarity (L/R) mismatch to verify new cable. Just checked 3.5mm connector T (tip, Left ch), R (ring, Right ch), S (sleeve, GND) against 2pin keyed connectors of IM series (left pin signal, right pin ground). Everything matches perfectly in this lunashops cable. Furthermore, going from original cable to a new silver-plated cable, the impedance went down from 0.9 ohm to 0.6 ohm, pure wire results in lower resistance, obviously.
After a few hours of burn in with IM03, my impressions in sound improvement are still the same as before. Though a sound is brighter now, without pushing toward sibilance, I think the biggest impact is in low frequency improvement with a sharper attack of mid-bass, and more rumble in sub-bass. If anything, sub-bass is where it benefits the most with additional dimension to it's texture. Also, the same improvement was a bit overwhelming in IM50 where sub-bass got a little too much for my taste.
