Thanks for your thread, if it was not for it I would have never know about it.
From what I have read discrete which is well built should provide a better sound and should not alter the sound at all. This means I will hear the sources I connect on their own without any added colouration of the amp itself.
This should pair nicely with the DD socket 1, I finally hear how MUSES01 sound without the amp altering it too much.
Congrats! I think you will like the MHd-Q7 & you're right, the form factor suits the ODAC nicely as per pix in my review. The only thing was that my mini-2-mini was too long & stiff that I needed bands to hold them together.
To me this is quite an underrated amp. It does the genre of your choice very well with finesse rather than just raw grunt power.
