I received these IEMs (SE535ltd-j REDs) a couple of weeks ago.
This is my first experience with armature IEMs and so far I like it. The source is a stock AK100. Despite impedance mismatch or whatever - I like the SQ.Can recomend this combo:)
Especially with Hi-Res files. Sometimes HD files may be gotten with poor mastering or with a very compressed dynamic range. Some recors sound with too much sibilance for me, but not many of them.
A difference between good mastered 24/196 and 16.41 (CD-DA) can be heard.
The only issue now is getting proper tips, still haven't decided what I prefer - foam or silicone ones.
And yes, the stock cable looks and feels cheapy. Will get an Oyaide HPC-SE pretty soon - even if it doesn't change the sound - I like it more aesthatically.
