Interested in a tube amp kit, I'm curious about this one. To me it looks like a good number of improvements to a classic amp, but what do I know? I've liked the sound of the couple of tube pieces I've heard and want to get my feet wet. Recently built a phono stage kit and had fun; this kit with the KT88's would be about at the top of my budget. I'd be pairing it with SDA 2B's.
