In a way it makes sense that the HXDA costs twice as much as... let's say an Archon. The HXDA is literally two different amplifier clones in the same box. There is a full and complete clone of the "Live at the Fillmore" amp, and there is also a a full and complete clone of a particular amp which was built to Jimi Hendrix's well known amp specs. Thus, you can dial in one, the other or both amps at your leisure. So, in a way, when you buy an HXDA, you are actually buying two amps and thus, it costs twice as much. Especially considering that even the transformers are hand built to custom specs. I'm not complaining about the price, but rather stating the obvious that it's twice as difficult to come up with the asking price.
