Two suggestions, for tubes there are a pair of BAT VK55 mono's listed for 4600.00. I have a VK55 stereo with my more efficient speakers and have plenty of power at 55W. The BAT amp has excellent bass and dynamics.
Another Class A solid state manufacturer is Coda. Their products appear to be beautifully constructed and have real world prices. I have no experience with the product but it is one I would consider if I was looking for solid state.
