Dacs Audio GD (19th, NFB1, Master 7, HE7...)

C'est tout simplement différents modes NOS.
voir ici: https://www.head-fi.org/threads/new-audi...02/page-41 

- NOS1: direct and most compatible NOS mode
- NOS2: using FIFO (I assume FIFO buffering)
- NOS3: accurate mode (preferred by mr Kingwa but not selected by default because it is more critical)

extrait:
"I know it sounds counter intuitive, I said mode 3 is more accurate as I read from mr Kingwa that it is the most accurately compensated. However, mode 2 uses FIFO mode, which may have benefits in suppressing jitter or noise. When I hear mode 3, it has a more smooth sound, and is a bit less dynamic and sounds (to me) more coloured, but also very pleasant. 

I suspect is that mode 2 and 3 do more than one thing differently. In mode 3 I hear more harmonic distortion (a little like when I connect my tube amp), and mode 2 to me sounds cleaner and things have more impact, which could mean more inharmonic distortion."

Je vois que tu as le streamer Mano. Apriori, et selon beaucoup d'utilisateurs du Mano (dont son concepteur), il est préfèrable de configurer sans aucun Jumper dans le DAC. Soit Oversamling x8. Bien plus précis et meilleurs espacement et scène sonore.
Quand je mets en mode NOS chez moi (j'ai un M7 Singularity et pas un HE7 Singularity), le son est clairement plus rond, chaleureux mais moins...accurate et j'ai moins d'espacement, d'air entre les instruments qu'en mode Oversampling.
