I'm very sensitive for sibilance. My current day-to-day player is cowon d2+ with fiio e11 amp, my earphones are AM6 HiRez. I use rockbox EQ to cut down some high frequencies: -7dB, Q0.7, 7kHz. Well, AM6 sounds very well on many compositions without EQ, but sometimes they harsh too much. And on some forums (primarily on russian player.ru) people told me that it's not AM6 has sibilance, it's because of d2+ crap. They told me that fiio x5, for example, sounds without any sibilance with AM6.
In my PC I have asus essence stx, it has better DAC than d2+, but for me AM6 sounds the same on both devices. OK, yesterday I've decided to go to audiophile shop and listen all players myself and choose best one. For testing I used flac files and some mp3 320kbps. For example, there were (the most bright and sibilance) Arena - The Great Escape, Arena - What if?, Twilight Of The Gods - Destiny Forged in Blood, Madonna - Love Profusion songs.
I've spent 2 hours for listening iBasso DX50, DX90, Fiio X5, iHiFi 770, HM 901, Hidizs AP100, HM 601 LE. And I hear no difference between them and d2+. The all have sibilant where d2 has (even 601 with multibit DAC). And they all play very good. But I can't tell that, for example, HM901 sounds better than cheaper DX50 or even d2+. They all sound good, can't say anything like "it has more air", "this one has huge scene" and this - "articulated bass" like most audiophile and tech-review guys.
So, what am i doing wrong? Is my earphones not good enough to hear the difference? Well, i don't hear any difference with audio-technica m50/beyerdynamic dt990 pro/vsonic gr07mk2/sure e215 on d2+/fiio x3 (sold it because of lack of EQ) and asus assence stx also.
Maybe my ears not good enough? Or maybe players don't have so much difference as audiophiles told me? But it's easy to find comparison of players and review guy always hear the difference!
All this is a bit strange. Read reviews and articles - so much difference! Listen with your ears - no diff.
Maybe I should use some special songs to hear difference? But if i can't hear it with songs i love, it doesn't matter.
