hi all,
i cant really seem to find much info on this..
apart from what it does is that it adds impedance on the output.. forcing player to output higher power giving cleaner signals.. and possibly removes hissing noise from circuits (is it?)

but there are those headphone with very high impedance,
there's also customs, ksc also has impedance modding..
so..

what i'd like to know is.. how does having the adaptor.. or changing the impedance affect the sq, eq, or signature actually?
is higher better or...?
what about impedance matching? what is so significant about matching it? how do i match my player to iem's impedance?

thx in advance for any contributions on this questions..

well i couldnt find much info.. that's one of them that i found.. probably..
anyway if talking about signal attenuation.. if the output is not strong enuff.. there will be some attenuation, or frequency drops..

im hoping someone here (eg: PcWork ) who does have those adapters can give his experience on that..

im not sure.. that's one of the thing i wanna try out.

hoping u'd offered.. was considering of getting one from u actually.. but i wanted to be sure first.
anytime ur free to entertain me? i live in bangi so if ur in serdang i can drop by anytime.
thx

will do..
when he's available that is..

from what i understand, what happens here is, the amp sees less resistance on low impedance headphone, hence current will flow through more...
imagine water flowing through small river (high impedance) vs water flowing through large river (low impedance).

there will be too much current being drawn from the amp, hence amp overloaded.

as for the results of impedance adapter, i dont find it to my liking.
it reduces hiss, but at the same time it lowers high frequency info, making the sound more closed-in, less airy, or in my own way of saying, less natural ambience and decay.
some people actually uses this to get a better definition of bass, dropping hiss (or noise floor) allows more things to be heard, especially low level details.
but higher resistance also will reduce the strength of the sound, too much and u might end up filtering the soft sound altogether.

i think its better to improve the grounding for cutting down hiss, or the power line for more current output. but im not an amp builder, i cant say much.
