Fascinating. For some reason this reminds of debates I've witnessed / tried to avoid about speaker footers (spikes versy mushy vs complicated mechanical devices) and how they utterly change the character of speaker x vs speaker y.
The only experimenting I've done so far is changing from midsize 'Olive' foam tips to the smaller size. Regretably if I'm listening at work I ocassionaly have to take them out and the midsize are *too* tight a fit for me to remove quickly.
With all that said, I don't think that changes in tips can be greater than changes in source; primarily the difference between the built-in DAC and a good DAC (i.e. a DirectStream or high-end DAP)... the whole point (for me) of this IEMs is their transparency. If you can't hear a difference of that magnitude, I think something's missing.
@Kitechaser I'm holding out hope for the Curious USB cable specifically because it *is* a bad DAC... to my understanding, great DACs do a great job of eliminating electrical noise and jitter from incoming sources. (Again, the source I'm using here is a bog-standard Lenovo corporate laptop). In my mind, *bad* (inexpensive or just badly designed I guess) DACs should benefit from good cables and good digital sources even more than *good* DACs (which have spent all the money to 'fix' incoming badness). So anyway I've plunked down my whatever is it was, ~$280, and we'll find out. But I'll use the cable for the Hugo2 for more often, and I'm hoping it will make a difference there. (although if I follow my own argument it may make *less* of a difference)
@csglinux Thanks for the links - searching for that stuff is a pain. Very insightful... I guess you have a headphone test measurement rig at home? .... As intense as I am about audio I'm always amazed at how much further other people are down the rabbit hole.
. So assuming I want to acquire and try all these different (non-Shure) tips, how do you get them? It may be unusual here, but I do *not* have 24 different high-end IEMs lying around like some of the members here... I have the Shures, my old pair of Etymotic ER8s which I've lent to a friend and ... a pair of Sony noise cancellers that I should now I guess sell. Oh and Apple Earbuds. but that's it.
@nanaholic I see that you have both a Chord Hugo 2, Sony DMP-Z1. Have you compared them as analog sources to the KSE1500?
