I'm a big fan of the Tubadour and have owned a few over the years. Having said that, I don't think AM's charming DIY web design aesthetic is up to par when dealing with $20k+ devices like the Wave. At that level I would expect more info, detailed specs (beyond just "S/N ratio>90db" which is all they say), better photos, etc.
Maybe that is all a work in progress though. I'm intrigued and will keep an eye out.
