After having many issues getting my Kabinet shipped it arrived today and at any listenable volume there is a pretty distinct buzz that doesn't happen when I connect directly to a powered studio monitor. I've used several of the stock profiles, the JHS paid pack, and several liquid profiles and it persists.
Cable is a brand new Klotz, tried with every intrument cable I own.
Tried multiple outlets.
Running both the Full range and cab sim with the recommended default settings for the Kab:
The above are the default settings in the app that I most recently tried, I've also tried master mono and both outputs in stereo.
When I take the cable out and plug it into powered monitors the buzz isn't there.
