I see that you’re new to Audiogon. Welcome. Hopefully you find it a helpful and friendly place to share ideas and experiences.
You also recently posted about a few other DACs - a list which also included the MMT. So, we can assume you’ve narrowed down your list to these.
For better feedback, it would be helpful to know:
1) what is the rest of your system. Best is if you put those details in the virtual system of your profile. A list in this thread would also be great.
2) what are your sonic preferences for the DAC?
3) are there other areas of your system you’re likely to upgrade and why? Are there shortcomings you’re trying to overcome w/ the DAC?
4) Given your list, I’m guessing you’re not significantly limited by budget but you should let us know what your budget is.
5) from the source you list, how will you be connecting the DAC (i.e AES/EBU, USB)?
Again - welcome.
