Has anyone played one of these new amps? I've been hearing them on youtube on various channels and the sound is just blowing me away. I don't know which amp it is specifically, I am a little confused as to the different models. I went on Sweetwater and there is a 150W combo. What TF? Are they kidding? And I found one demo on youtube and it was a 20 watter, but he said it was $2K. I'm just curious if anyone has spent any time with these and what their impressions are. And are some of them considerably better than the other?
