Impedance/Resistance Adapter from APureSound.com

[MrSlacker]

Was just looking at cables on apuresound.com and noticed that they have added a new item. Looks like it is a Impedance/Resistance Adapter. Looks around the same size as my radioshack 1/4th to 1/8th adapter so its pretty small...

What exactly does such an adapter do? Would I see a benefit in using one? I have one of their cables so I know quality is top notch... but is this worth it?

Seems like there is a discount for first 5 orders so i dont want to miss out on a good deal....

Has anyone heard that adapter already?

I am assuming one of its intended roles is to act as an Etymotic ER-4P to ER-4S converter as the official etymotic one is a 75 ohm converter. I believe there may be other IEM's that have similar converters.
These IEMs were initially designed for a flat response with the 75 ohm impedance, but have had their impedances changed in order to be more easily driven by un amped portable players.

I do know for a fact that the ER-4S has a flatter response curve in comparison to its lower impedance brother. Many members here will also attest to an improvement in sound overall, although I personally have not tried it.

interesting to see what this one does sound quality wise...

I'd imagine it doesn't sound any different than a high-end impedance adapter (like the ones Moon-Audio offers) or a cheap, DIY one. The point of an impedance adapter, in non-Ety cases, is to make sensitive headphones easier to drive for certain amps or to match impedances a little bit better with amps. Usually the effects are pretty small but still noticeable, and in some cases they are a necessity. There are some threads on this already, do a search and read up.

I have one of Dr. Xin's little 75 ohm plus x-feeds plugs. Works great in what it does.

wanted to bump this thread to see if any1 got one of these? still thinking about ordering one...

Interesting site. Are people really ordering custom Recable and Mods of the $20 Koss KSC75? Life can be stranger than fiction, I say.

(I'm intrigued by the impedance adaptor too. Hopefully someone knows something about it.)

The impedance adaptors are mini jacks.

MrSlacker just shoot Alex A.K.A. [AK]Zip a PM and ask him. He can explain it to you. He is apursound.com in case you didn't know. His work is first rate!

I talked to Alex... I also have one of his mini-mini so I know how good his work is. But I wanted to see wat ppl think 1st
