Thanks for posting, that rabbit hole lead me to this neat nugget in post #12, quoted below as well. (Not a Jeff post).
drlowmu's (Jeff's) Amp Discussion
I too have been looking for a good amplifier, ..........for over 50 years now. In high end audio, you first need to have a two way speaker that is 101dB or more efficient. 98 dB won't do. Think vintage movie theatre. ALTEC purchased used, can be a great speaker choice. Own a...

“Some maths and facts.
The first watt is the most important watt. Majority of the musical listening happens less than one watt.A headroom of 2 more watts is safe to accommodate those Crescendos.
2. Class A amplifiers by design gives distortion free music even at sub watt levels.
3. An amplifier which is rated for 100 watts, will sound double loud as that of a 10 watt amplifier ( not 10 times!)
4. Using the same amplifier at same volume setting,a speaker of 95dB sensitivity will sound twice loud than when using a 85dB speaker.
5. To summarise, A 2watt amplifier powering a 105dB speaker will sound as loud as a 200watt amplifier powering up a 85dB speaker.
Hope this helps.
As far as dynamics, SE amplifier have a special sound signature,They have restriction in producing low frequency notes with a punch, because of core saturation happening in SE output transformers. PP design does not have that , so can give more punchy bass and may be more subjective dynamics. SE amplifier have a property to reproduce human voices and instrumental timbre with almost life like presentation. It's not that it's weak in dynamics or bass,the truth is our ears have been tuned more to a bloated bass than what actually it is.Hear a SE amplifier and then your perception of bass will change. It's not about punching , it's about just enough bass at just the right time., One can say more natural bass or bass as it is intended to be.”
This one is a classic also. 😁
My family room (where I have my audio stuff) is suffering a mess-loading effect. A few things like backpacks from the recent trip, a pile of rekkids, an unfinished LEGO set, various things that need filing, etc...
I still remember talking with Gayle Sanders (co-founder Martin Logan, current owner of Eikon Audio) and he mentioned Roger Sanders (no relation) who was demonstrating his electrostatic speakers in similar bobsled seating configuration somewhere on the same floor of the hotel. Gayle simply said to me, "Bless his heart." 🤣
I did that with the old Admiral hi-fi console in the basement when I was a kidlet. Three years old, standing on a chair next to it, playing records all day long. I mean, was there any other way? 😁

I fill my room with 1/4 to 1/2 watt of SE-DHT music because of my speakers.Thanks for posting, that rabbit hole lead me to this neat nugget in post #12, quoted below as well. (Not a Jeff post).
