I wasn't able to play any TR's locally, I had heard a combo in a store that a guy was playing through and it sounded amazing. I'm not sure which model it was though. I had researched some stuff about them and had heard a lot of great reviews. My judgement to try one was based off of a couple youtube videos that quite frankly didn't even come close to doing it justice. I'm the oddball as I didn't really get the Bi-Onyx based on the clean tones, I wanted a really unique gain channel and it is way cooler than i imagined. The Anderton's demo of it sucks and I'm actually amazed they got such a crappy tone out of it. I tweaked the knobs to between 11:00 and 2:00 and got a great tone in about a minute. I will say the Boost is super loud but I like the push it gives the amp.
I had considered the Sensor as well but the features on the Bi-Onyx (clean/dirty with boost for each channel) and of course great reverb. It also takes pedals well - although I haven't tried the loop yet, I'm mostly a boost guy so I like having a variety of them to add a little push on the front end.
I will say the amp seems to be built very well, for such a small headshell it's HEAVY
