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

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.

I have had this SET set up since 2009 and can honestly say that I appreciate it more than ever.😊

@bache With the right speaker enclosure, Tannoy dual concentric 15" speakers and many other efficient speakers extend down to below 30 hz. Not to mention that 90 percent of the music is in the midrange frequency. Who is stupid now? I didn’t want to do this to you but you made me do it. Ignorance can be a blessing. No wonder why Tannoy was the most widely used speaker in studios around the world, including Abbey Road. I guess, they were stupid too.

@tannoy56 I only ask sincerely and not to disparage “bache”…

but how can you even make sense of what he said?
