I read in the ATH-IM series thread that the IM02 is very sensitive to source. It needs a DAP with output impedance with 1 ohm or less to bring out its best. Most other IEMs are not that picky.
Yes, a good review, I just am (uneducated) guessing other factors are involved- as I said, in my experience the sound did not strictly correlate to output impedance differences- my favorite source was 3.something ohms, my least favorite was 0.6, I thought "well maybe I'm just experiencing favorable distortion", but then it sounded just fine with other low impedance sources. IM02 is the most dramatic, but I have used others with their own incongruities, and others still with very minimal variations I imagine are "true to source" as it were.
Anyway, getting a little off topic- I only meant to posit that as a possible reason for bouyouhou's dissatisfaction with the Plenue compared to iPod- impressions from david and others seem to indicate s-em9 is fairly stable in that regard so it might not be the case at all and entirely the character of the Plenue itself. I just hope it goes well with my AK Jr.
