Ive been looking at this amp for over a month now and for some reason just have become obsessed with it. I've heard that the series one stuff from Blackstar is miles ahead of the HT line.
Well, it is all-tube for one. Plus it's got the power-damping feature. And I'd imagine it's just higher quality. I've got an HT-5, but it pales in comparison to the Artisan 30 I played. They are a pretty cool amp company, though.
