Yes imho there is a risk that this is audible the only way to get proper hf response with this player is to use hirez material or maybe upsample your cd stuff :) what is the hf drop at 13khz or 15khz ? That 20k is gone down -5dB can bother young audiophiles but thats does not seem to be the core demographic for the product. If a portable hirez player is a bit anochronistic would it compete as headphone amp ? Or is the battery power such a compromise such that it easilly beaten by a more dedicated headphone dac/amp . Or maybe this is not anachronistic to some users ? Anyone prefering keeping a separate portable music player these days -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
