There is someone in head fi too, in IEM forum, saying that source doesnt make difference. Obviously cable makes a difference seems utter joke for them. Everyone just different, i have ier-z1r, n i dont found the difference in using my s8 with my desktop rig(bifrost multibit+aune amp) except just some dynamic that come from the power drive the amp has. I just didnt hear anything, n before that, i have ex800st+EA janus, n used the same desktop rig compared to phone, i dont hear the difference, i try but cannot hear the difference, then just 1 month ago(kind of), i sell my z1r, bcs it just not fit for my ears, and the subbass killing me, it does slam si hard, n i dont like prominent bass compared to other ranges, then i planning to bought another IEM, but decided to bought dx220 max just days ago, before all this, my first bought into IEM realm was CA comet, but the right side was kind of not as loud as the left one, its my fault for not taking care of it, then after i sell z1r, i use it again n found it not that bad, then after i decide to bought dx220max, i felt like i definetly heard differences between sources, that i have not heard. I definetly heard the difference of how the max rendering the song compared to my phone. So to my knowledge n experience, as long as u have entry to mid range IEM, trying much more higher up source, or maybe upgrading it gonna make the difference more apparent, then why my desktop rig doesnt make difference, well the thing is that i found out the amp tube, some of the light is not as bright as some other, but bcs it is still producing sound so i dont think about it much, so then it could be one of the factor, n then the connection between the pc(player) to the dac, im thinking the pc electric is not clean, bcs i found out it does electrified when i touch the dac or some parts of the amp, n ir could be the cable that goes from dac to amp. Well the point is i proved my self that source do have an effect, in fact imo right now, source is more critical than IEM, ur source need to be able to producing those details, so that the IEM could do the same, obviously if the IEM is not quite good, then u could say its bottlenecking the chain. Now i need to try cables n found an used andromeda, then im done. Sorry for blabbing.
