I bought one yesterday and made some clips comparing it to my Axe FX 3 if anyone's interested.
IMO it's a very cool unit especially for the price. You get a two channel tube preamp, plus IR loader, power amp sim, and boost. All analog and tube front end, digital back end, and MIDI programmable. It's not competing against the Fractal gear, it's competing against things like the Strymon Iridium type pedals.
Sounds awesome to me with very little fuss. Clean channel is pretty flexible, dirty channel nails all the BE tones of course, takes pedals really well, works with effects really well. I hooked it up in 4 cable method into the Axe 3 and it's just awesome like that. You can use the MIDI switching to change channels too with scenes. Pretty damn cool.
Again, $500 for a two channel tube preamp with footswitch and power amp/IR to go direct, not going to find a lot that can compete with that IMO.
