Class A in itself benificial?

When we search for the holly grail, we google "best amp in the world", "best sounding amp ever!".

There is no such thing as a best amp in the world.
Just because the straight wire zero distortion, zero coloration theory is all wrong. Even the shortest straight wire produces distortions and colorations.
In practise, the human senses are highly individual, subjective.
This is a stupid goal, a stupid question, because no one would ask for the best steak in the world or the best wine in the world. All those experiences have to be tasted to judge and everyone will judge different.
You should have a clue for your goals in audio. If you think that zero distortion is attractive, go for such an amp. If you like tube sound, go for a tube amp.
If you like K2 distortions, go for single ended.
Thats how someone chooses, because he knows his preferences.
And preferences can change with individuals, sometimes they change with daytimes or seasons or moods. So for every mood a different amp. How about that?😀

A reasonable reason to opt for Class A amplification could be to achieve smooth transitions, evading the nasty switching bursts. Nothing is in itself beneficial so a smooth transition is not generally an objective. The switching-mode pulsating power supply, also called Buck converter (or bucks bunny converter) is anything but smooth.

Likewise, digital transmission consists of discrete switched pulses. A pulse arises in response to a switching action. hpro`s assumptions are fundamentally correct.

Instead of "analog", "continuous" would be a more appropriate word here. Nature constitutes a continuous system where gaps, discontinuities, delays, periodicities can never occur. The audio signal is more naturally transmitted in a continuous technical fashion.

I also have some panels dedicated to DC for amplifiers. Very quiet but daytime only.

It's probably the batteries, the old problem of retaining current, that will constitute the main problem for using solar energy. I'm not an expert in this field but producing and disgarding them seems critical ecologically.
Please correct/enlighten me on that.

Just finished reading the 21 page owners manual of the first series of X amplifiers. It's proza, so witty and informative that only on the base of that alone you want such an amplifier.

It really depends on your choice of storage and what your needs are. For home use a vast majority of the time, weight and volume are not constraints. In my case it wasn't, and for that reason I didn't mind good old fashioned lead acid wet cells because of their recyclable factor. Where I am its "easier" to recycle lead acid than lithium ion as the support network to recycle lead acid where I am is far more mature (we get credit for our spent batteries when we replace them). The only real annoyance is its a pain to transport them when each 6V battery weighs 57kg, but the manufacturing plant itself is in my province so its not a horrible drive to get them.


Apologies in advance for the threadjack.

No your comment on solarpower is okay because I asked to get enlighted.
I hear dreadfull stories about those Lithium mines in Chili I believe destroying the land just like brown coal day-mining.
If lead-acid can be recycled without to much pollution and hassle it's great of course.

In a Mr.Pass article from the year 1978 you find chapter with the futuristic title " Heat and Ecology ".
Yes 43 years old message , and you can learn more why class A is favored

Very nice contribution indeed! Start reading immediately.

Thanks the ecological part:
"...the ecologically oriented audiophile may wish to operate his class A amplifier only during the winter, when he would otherwise be using his heater, and revert to a class AB design amplifier during the summer."

Good thinking!
