I'm using this with a Kemper Profiler and it sounds pretty great. Stereo effects sound heavenly with the width set to about 145% and I get lost in them. Has the low end oomph and growl that sounds more like a tube amp than others I've heard. I compared it to the Kemper Power Kabinet and liked this much better. Most of the built in speaker profiles are very usable, and I use a simple midi switch pedal to flip between them to find the best for whichever profile I'm using.

The width control and speaker profiles are the most useful, as well as the ability to use each side independently and run direct out to another cabinet or the PA. The built in kickstand legs are great too.

It's very easy to get great sounds, just hook up your modeler, disable any cabinet emulation on your modeler, and turn the dial to audition speaker profiles.

The Cabinet is very well made and seems sturdy and built to last. The AES input does not work with Kemper in spite of trying several S/PDIF to AES impedance converters. I've seen others have the same issue and never get it working, but one or two did after an exchange. I suspect it's a bad batch of AES inputs. The analog inputs sound great, but I don't like when a product advertises a feature and it doesn't work.

If I were to buy two Kemper Power Kabinets to run stereo, that would cost around $1400, so this is something of a value over that option.

I contacted Line 6 support about getting the AES input to work with my Kemper Profiler. They took 3 business days to respond (had to wait over the weekend), and weren't helpful. The problem was never resolved.

It checks a ton of boxes, for me the biggest of which are great sound and stereo. It's not something I need to make great sounds, but it sure makes it easier and faster.
