Thanks for the concise review. I'm waiting for mine to arrive in the mail. I'm sure I won't be disappointed.

High sensitivity iem? SM64? I think you made a mistake, with a very high impedance, SM64 needs much higher power/current compared to the "regular" or "common" iems.

Despite it's higher impedance, I find that it doesn't require gobs of power as the sensitivity is still quite high. Is it more power hungry than the normal IEM? Yes. Does it require an amp to sound good at normal listening volumes? No.

I'm planning to get one of these DAC/AMP from a Chinese brand as my first desktop gear. The other one I am looking at is the not as powerful and of course smaller and cheaper Aune X1, which is around the size of an ODAC. How is the size of 11.32 compared to the ODAC ?(I'd like a neat table)
