I use it for 1 week and I love it, I tested the Mackie Big Knob, which had not liked the noise level because it changed the sound, although that level was more than interesting feature especially for the price.
What I like most is the sound is rather transparent from the Big Knob, more quality headphone outputs is terrible and Crossfeed is more significant.
Manufacturing quality, nothing at the level of pro knob breathes, and the hull is solid. It is designed in Germany not China and it shows.
What I like least is the absence of TalkBack, that's why I put 9.
The value for money having regard to the sound and build quality is excellent.
