If that's the case, then an OPA2132 or 2134 is right up your alley.
You know, the FOTM (Flavor Of The Month) thing gets out of control around here a lot. Just because there's a lot of good amps available these days, doesn't mean a CMoy with an OPA2132, OPA2134, or OPA2227 sounds like cr*p - it doesn't
. It will still beat the pants off of any portable CD player and will do the same with iPods and such if using loaded headphones.
Even so, your statement of using ety's and sounding soo bright is a good fit for the warm opamps noted above. They get a bad knock these days when plopped in a circuit with high-powered power supplies and hot rod buffered output stages. However, in a CMoy, those opamps will sound warm, detailed and tube-like sweet. Just lower the gain by substituting different resistor values (detailed in Tangent's tutorial) and you'll be fine.
P.S. Lowering the gain, which is something you probably need to do with IEM's, makes it even more important that you stick with the ultra-stable opamps listed above, IMHO.
