What opamps do you have in your SM? I had some trouble with opa 627(only non CA) and e5c's but nothing with my sensas, and I haven't had any hiss with either iem with onsemi SA 5534 obca. Opa 227, AD 797 and some others are also very quiet. The AD8397 is also apparently very good with iem's though I haven't heard it yet.
Well, yesterday evening I tried the OPA627 (not yet biased to Class A) and I immediatly found that they produced more hiss with my UE10s
Previously I used the N5535 (CA) and though they produce some hiss, too, it's better IMHO. Maybe it has something to do with Class A biasing, though I'm not sure, on the contrary, I would have thought Class A produces more hiss just because it needs more energy. I haven't yet tried my 604s - non Class A. Yesterday I was thinking of getting the Class A adapter from Xin (in order not to ruin the OpAmps by damaging their legs to bias them to CA), now, after the site update I can't find it anymore. I'm not sure, the new SuperMacro isn't CA out of the box, is it?
I considered buying apair of AD797 OpAmps some time soon. At the moment I'm simply looking for a solution to get my iRiver+SuperMacro more silent - maybe another OpAmp will already help or either upgrade the SuperMacro or change my source :/
Upgrading tme SM looks more tempting though *g*.

Hehe, Hi Gordon!
Any update on your UE10? Did you need new impressions??
