If you are looking for a good 845, I would recommend the Melody M845 monoblocks. There is not much info on them online, but with the right tube combination they can beat out the Sophia Electric 845 and are much more reliable. Bass is by far the best I have ever had and you also get all the magic that SET amps are known for. Recently I was able to demo a pair of the Melody's next to another well known 845 ($14,000 Audion Black Shadows) and it held its own remarkably well.
If you want to go the 300b route, then the Coincident Frankensteins or Wavelength should be at the top of your list.
If you don't mind a little noise, the Joule Electra Monoblocks are also stunning and the headroom, dynamics, and magic are there, but you have to get over the hissing of the amp.
