I have met Mike Pascale, the designer of these amps, nice dude and he makes some sweet tube amps that are all hand point-to-point wired, no circuit boards. Have not tried or heard his bass head but they are supposed to be really nice. When I did a price check I couldn't find a price for the bass head but the guitar heads I think were in the $3,500 range so expect the bass head to be expensive. Check out the link posted above and contact Mike for the actual price.
