Default Listening and RMAA Tests, Cowon S9 (vs. D2, O2)

First the test with my own ears. I matched the volume of the S9 and O2/D2 to within 0.5dB (vol. 16 on the S9 = vol. 14 on the D2 = vol. 24 on the O2). I listened to various kinds of music with my UE11 IEMs, switching the phones between the three players. I used flat settings without EQ and enhancements, and also my favorite BBE settings (BBE@1, M3B@5, MP@on, no EQ, no other stuff).

The S9, O2 and D2 sound very much the same to my ears, hardly any difference at all. The S9 and O2 do sound the tiniest bit "richer, fuller" than the D2, though, perhaps because of less bass roll-off. The S9 furthermore has microscopically less "harshness" than the D2. However, the differences are so incredibly tiny - to 95% of all people all three players should sound absolutely the same. These negligible differences are only apparent in an A/B test with matched volume anyways.

Both the S9 and D2 hiss pretty bad with my UE11 (18 Ohm, 119 dB/mW) - the O2 doesn't.

Here's some RMAA comparisons:

RMAA: S9, O2, D2, X5 - 16 Ohm Loads, Full Volume
RMAA: S9, O2, D2, X5 - No Loads, Full Volume (how a headphone amp would "see" the players)
