I actually bought a 12 MTK too, after all. Decided I wanted full analogue summing and the UFX woulda given me only 4 outputs from Auria. One other unexpected plus of the 12 MTK was the form factor - turns out it fits like a glove inside a Magma XL controller backpack!
Inital impressions are - the DAC sounds very smooth (hopefully not too much so). Certainly pleasant sounding when listening to my music library. Will hook it up to the rig soon an let you know what I think. Right now I feel like I like the DAC sound more pleasant on headphones than my UAD Apollo twin (wtf)
The pres are pretty quiet I must say! Don’t mind the build q either tbh, good enough for me.
