I came from recording with FMR Real Nice Preamps, as well as a Joe Meek VC6Q British Channel into an RME ADI-2. The preamps and conversion in the Qu-16 are far superior. That’s not a huge surprise, but I was actually disappointed by the RME after recording through the Qu.
The noise floor is much lower with the Qu, I can hear delays fading away almost endlessly into nothing. My Strymon pedals sound fantastic on the mix outs. The mixer itself is totally silent, no fans. Great design.
I like the D/A as well, I can hear much more detail now. Even the headphone out is a step up from the RME.
I am recording into a Macbook/Logic and I haven’t had a single issue. I haven’t used the DAW control functions as I’m getting out of the box as much as possible.
It’s been a big sound and workflow improvement for me.
