How important is the efficiency of a speaker to you?

I went to an audio meeting recently and heard a couple of good sounding speakers. These speakers were not inexpensive and were well built. Problem is that they also require a very large ss amp upstream to drive them. Something that can push a lot of current, which pretty much rules out most low-mid ( maybe even high) powered tube amps. When I mentioned this to the person doing the demo, i was basically belittled, as he felt that the efficiency of a speaker is pretty much irrelevant ( well he would, as he is trying to sell these speakers). The speaker line is fairly well known to drop down to a very low impedance level in the bass regions. This requires an amp that is going to be $$$, as it has to not be bothered by the lowest impedances.

Personally, if I cannot make a speaker work with most tube amps on the market, or am forced to dig deeply into the pocketbook to own a huge ss amp upstream, this is a MAJOR negative to me with regards to the speaker in question ( whichever speaker that may be). So much so, that I will not entertain this design, regardless of SQ.

Your thoughts?

Amazing how complex and convoluted this discussion is.  I don't think there's a good answer here.

Except, having a Quality tube or solid state amplifier with plenty of power is undisputably a good thing. Yes there are speakers that can run off of 10 W of tube power.  Although this confuses the hell out of me.

Sensitivity of speakers is really confusing to me except that more sensitive speakers can be played with low power tube amplifiers and there may be some value in pursuing this because there are plenty of really good tube amplifiers running off of low wattage this can be a good thing. And we all know tube amplifiers are better than solid-state.

It's also good to buy a dog rather than a cat because the cat could care less about you.
