Sorry the dumb question but not having a great perpection of English nor being a mathematical genius, I would like ask what Common Sense audio mean say that his full ranges operate in the power range of 1/10 Watts.
(normal listening level will be about 1/10 watt).
They mean say 0.1 Watt or 1 to 10 Watts range?
Thanks

OK, if 1 W = 94 dB/m, then 1/10 [0.1] W = 94 - 10log[0.1] = ~84 dB/m on average or fairly loud. If this is a peak power rating though, then most recorded music's ~ + 15 - 20 dB peaks means your average is only ~64 - 69 dB/m, which is a broadcast TV/close neighbor friendly level.

Just see in the CommomSense site this comment on the E34 amp down tha page:
Conservatively rated at 10 watts per channel (average listening level for our Audio Nirvana full-range speakers is 1/10 of a watt).
So wonder if this is possible in the Classic Alnico line 94 or 96dB?
This is a optimistic estimate?

Once I heard an MC Intosh system of 1 Kw per channel, paired with a pair of JBL Everest DD66000
The sound was excellent, and when I observed the VU, the needle did not exceed 1 watt in the musical peaks .....
So, there were 999 watts left in the system ?
Power (watts) vs. SPL (sound pressure) is not linear, it is a curve (logarithmic).
"beyond those demanded by manufacturers"
"each one carries the water for his own mill"

I don’t doubt that the average could be that low for some types of music. I am using 95db/w Pi 3 speakers and right now I am trying a 5 watt SE KT88 amp. I have been monitoring the peak voltages and even 1 watt rms or 4 volts peak is usefully loud. The average voltage readings would be very low and within 1/10 watt which is roughly .9vrms.
It’s a bit misleading as a measure of power requirements because average means nothing if you can’t reproduce the peak dynamic range of the recording. I can get by with 5 watts and it will get quite loud but if I had to say how much would be plenty I’d say my 25w Aleph J will play pretty much as loud as I’d ever need it in my smallish 250sqft room. The 100 watt F5 V3- well, lets just say it has some headroom.

If you really want to know, have a look at the thread linked in my sig line. For small rooms and efficient speakers voltage levels can be surprisingly low.
Note too that normally mastered music had* an average to peak ratio of 18dB. Meaning that if you are listening at 1/10 watt average (0.9v volts), peaks wound be 7.15 volts. An amp that can supply a clean 5 watts RMS could handle those peaks - just. If it soft clips, you could cheat a bit.
* I say "had" because the loudness wars have changed that. Modern mastering is much less dynamic. The up side of that is you need less headroom. 🙂

And for those flush enough, and not requiring arc welder duty, a monoblock pair are quite delightful
Yes, I have plans to build one of those. I’m gathering parts and recently found some heatsinks that are suited to the ACA. My goal is to have a bunch of amps of different topologies and power levels and I am well on my way in SS with plans to build up some tube amps in the near future.
We shouldn’t dispair about some pop music being compressed and limited. There are still lots of excellent new recordings out there, not to mention the gazillion or so undiscovered gems in the vast library of older music. Having the correct speaker for using a low powered amp is an important factor as well as room size and most of all, listening preferences.
The problem lies (for me) that I have great fears that these aberrant recording practices go from pop to "serious" music...😉
You imagine ? It would be like saying to Marta (concert that I attended recently) that she does not worry about beating the piano too much in the strong musical passages ... ("fortisssimo")
The engineer on duty, (if "do not worry", as you say), will throw away all that talent and effort ....
It seems that there is a worldwide consensus not to worry too much about preventing catastrophes, in the end, George was right: "All things must pass" ......🙄

I hope that will never come to pass. What gives me hope is the number of musicians I have encountered who care deeply about the sound of their performances and recordings. My feeling is that many of them view the recording process as an extension of their art.
About unusual recordings I have listen past week this Cembalo German digital recording released in 1990 that is labeled Stereo on the cover, I had always listened this CD on speaker and feel strange it dont have any ambience, so past week I have listened it on a HifiMan headphones and was shocked to discover it is a mono recording and yet worse it is a very close-up mike position, the soundstage is very narrow and flat, it dont have any depth, its a very strange recording.
