Presonus Quantum 2626

Initially was happy with the interface. Ignoring the fact that the software lacks some of the mixer and routing options of the competition it worked reasonably well and I could incorporate my modular system in Ableton. After a few months though the Main Volume knob started crackling whenever I turned it. An issue that then later extended to the headphone knob as well.

That's disappointing in itself but by now I sent it twice to Thomann to get this fixed but both times it would come back and be ok for a week and then the issue would surface again. First just a bit and then stronger and stronger. The second time I sent it for repairs they even managed to send it back to the wrong address even though I mentioned the new one in the correspondence and it's saved under my profile. At this point I've given up on Presonus products and on Thomann. Looking into MOTU now but definitely not from Thomann.
