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?

Tvad, I should have posted about driver in house design vs mass market poly cones, on the topic Harbeth vs Tyler. i goofed up, and mixed comments. Back to topic of tube amps transformers and the resistance from the motor and crossovers in speaker designs. A low volt tube amp, or lets say one that has trouble maintaining proper volt current when demand gets high, will not bring out the FULL potential of certain demanding speakers. Go to Jadis' web page, look inside the DA88. Designed to meet any demand from any speaker. Quality doesn't come cheap. Although certain chinese labs are comming along quite nicely. We can talk theoy here all we want. We are more interested in which labs are actually producing a tube amp to meet demanding power hungry speakers. I'll leave the tech stuff to their engineers. I am only interested in the end result. Does the setup produce a high fidelity musical image? Thats all, nothing more.
Wolcott produces tube amps to meet the demands of power hungry, low impedance speakers. As does Music Reference, if I'm not mistaken.

The best amp for meeting the demand of power hungry speaker is called a transistor amp. A person attempting to use a tube amp on said speakers is called ignorant (I am being kind)

No, I suspect you are interested in your own opinion ...

Yeah but can they produce a musical image equal or similar as does 2 tube amp labs that i have in mind. Its all about who can get closest to the high fidelity musical image. Audiofeil feels since i know nothing of the tech side and so suffer from deafness. 30 yrs audio critque and now I am deaf.
Dear paul: The statement is totally accurate, it is not talking about " speaker has a benign impedance curve across the frequency range. " like you state.

regards and enjoy the music.
