Thanks for your answer and your offer to provide me with further information!
Regarding the soundstage, I have found that various sources (CD players, Dacs) can have a significant impact upon its width. My hearing is probably not trained enough to hear depth or height very well (I’m an avid headphone listener) and my speakers system + room is not very helpful, but I hear the width clearly. I have heard these soundstage width differences easily in speakers as well as in headphohes. So, compared to any other sources you have heard, is Onyx’ soundstage broader or narrower? I don’t have a specific track to test soundstage width, for me it’s pretty apparent on any material. If you need something very specific, maybe, from the top of my head: track 1 "Yulunga: Spirit Dance" from Dead Can Dance - "Into the Labyrinth" (after min. 2:53 or so). For example, the hard panning of the left side maracas at min. 2:53 and the rest of the track following this. This is, by the way, a track I’m using to check for reasonable bass extension (tympani at 2:29 and a few times later - not extremely deep but it’s about my threshold for "reasonably extended") and tactility / snappiness / punchiness (from min. 3:02 on).
As for the highs, I often use the beginning of track 7 "Desolate Mountains II" of Jan Garbareck’s album "Visible World". I pay attention to the actual treble extension as well as to the chromatic contrast between the various percussion "notes" - the Gungnir Multibit tended decrease a bit the highest frequencies, accentuate the mid-treble (8-10 kHz? - I don’t know the exact frequency band) and attenuate a bit the aforementioned chromatic contrast (making everything a bit more uniformly grey and metallic). Small things, but I could hear them clearly and it did bother me. How do you find the Onyx compared to my description of the Gungnir?
