A few weeks ago, the bass driver in one of my Super.Fi 5 Pros died. My 2-year warranty has expired, so I'm looking for a replacement set of IEMs rather than taking advantage of the 25% discount which UE offered me.
The biggest complaint I had with my SF5Ps was the amount of hiss coming from my iPhone and iRiver H-120 (both unamped). It greatly limited what I could actually listen to with those sources. The Ratatat remix of "Stunt 101" and Darkthrone's Transylvanian Hunger both sounded great in their own ways, but Arvo Pärt's Te Deum and Bill Evans's "Waltz For Debby" were essentially unlistenable.
Judging by posts on this board, hiss in IEMs seems linked to impedance and sensitivity. (Poor quality sources can also be an issue of course -- but given that FLACs out of my iRiver's lineout hissed as much as 128 bitrate MP3s on my iPhone, I don't think this was the problem.)
What I'd like is to find some IEMs which will definitely not hiss with either of my sources. I value pleasurable, engaging listening over analytical, flat-sounding listening (so no Etymotics), and I'd like to spend less than $200, but can spend a lot more if someone is persuasive enough. I don't want to use an impedance adaptor, and I'm happy to take a knife to a minijack to make it fit in my iPhone.
Is there any consensus as to whether, say, the relatively high impedance q-JAYS definitely do not hiss where the SF5P does? If it varies from IEM to IEM, can people report on the amount of hissing they've experienced with the iPhone and iRiver -- especially with the q-JAYS and Atrio M5s?
Some sample impedance/sensitivity specs
Super.Fi 5 - 21 ohm / 119 dB
q-JAYS - 39 Ohm / 95 dB
Atrio M5 - 32 ohm / 112 dB
Triple.Fi 10 - 32 ohms / 117 dB
SE530 - 36 ohm / 119dB
Westone UM2 - 27 ohms / 119 dB
