Tube amps and speaker ohms


In your opinion , do push pull amps work better with 8 ohms or 4 ohms. .I am under the impression the lower the ohms, the more power is demanded from the amp....Another question, are there low powered SET amps ,and high power SET amps?
I'm looking at a 40 watt 845 tube amp for my 8 ohm, 89 db speaker.. just cked the Thor has a 86 db W18 midwoofers(2 per cabinet) and a 88 db tweeter. Will an 845 amp rated 40 watts be able to drive the 86/88 db speaker? With authority, bass, mids, highs, in dynamic sound stage? Synergy? Or poor match?

Hi ...I like my solution to the same situation you have. I like the SET tone but I want to be able to use a wide selection of speaker. The answer for me was the TAD 60 power amp. It is very flexable in that it is rated at 30 watts in triod and 60 watts in UL mode using kt88 or 6550 powers tube. Using el34 , 6ca7 and the like has a little less. However the neat thing about this amp is that you can bias it into Class A and it sounds very much like an SET
