What is your take on high efficient speakers vs. low efficient speakers?

To write off all SET in this manner is total nonsense. I've had ss class A and AB, push pull tubes with various power tubes, and SET with various power tubes. Low, medium and hgih sensitivity speakers with the above. So, it seems my evolution towards SET is in fact, a descent into inaccuracy according to mijostyn. I guess having living, breathing performers in room is in fact inaccuracy.

My Line Manetic Field Coils Speakers are 105db Sensitivity, Their are dynamic and yet smooth, musically invovling, My Classic Audio Loudspeakers are 100db Field Coils.

Both of these speakers to my ears give one dynamics as closer to live performance and as a result are more emotionally invovling and exciting to listen too. it does not bore you to death.

Been their and done that with low efficent speakers and high powered Tube or Solid State amps never again.

@charles1dad , dogmatic maybe, presumptuous, not at all. What you are listening to is a study in colored inaccuracy. You can like it all you want but calling it accurate is a big stretch. 

Maybe not dogmatic. But you are like a dog shaking a bone. You just don't want to let it go. And @charles1dad is probably the most cordial guy on this site. He makes disagreeing seem like something not so bad after all.

High Sensitivity Speakers without support sub or build in active woofers got low performance to produce low bass but some listeners dont care about low bass' They looking on techical characteritic and stupidly believed , what it say

Yes, this accurately describes my copacetic listening scenario. 8 watt SET mono blocks driving 94 db sensitivity /14-ohm impedance speakers. My typical listening levels sitting 10 feet away are  C-weighted 65-75 SPL

Can dip to the mid 50s (softer passages) most ofren peaks (mid 80s).. I can listen at louder levels comfortably, but no need to.

About the same levels for a large portion of my music enjoyment (right now averaging just over 65dB's C-weighted with my evening listen of Keith Jarrett's 'The Carnegie Hall Concert'), except with a range of well-recorded and not too dynamically compressed classical recordings, some electronic genres and watching movies, where higher peaks (via a wider dynamic range) do occur.

At these very satisfying listening levels the SET is far below 1 watt of power (Small fractions of one watt) and doing so at a very low level of distortion (As you note). The sound is very tactile, resolved, pure, natural and quite emotionally engaging. Key take away is the amp and speaker must form a compatible match.

With 8 watts of SET power given the speaker context, listening levels and distance this combo should be perfectly suitable. Sounds to me like you're hitting the right notes, so to speak, from your descriptions.
