Explain what is a clean power amplifier?


Can someone explain what makes and define what a clean power amplifier is or does?  I have googled and searched the forum and haven't found a simple explanation to grasp. 

Thanks

Now I may not have done my embedding (mahgister) or integration of my system in my house quite the same as anyone else.
Nobody can do the rightful triple embeddings in the same exact ways, with exactly the same devices and the same materials.... Why?

Simply because we must create our own particular solutions. for our own particular resonance-vibration dimension,for our own electrical grid, for our own acoustical space, different from gear to gear and house to house, and room to room.... Different also in price and time invested....

The only common thing between us will be the creativity....And some commonality of the problems then some commonality of the solutions.... My best to you....
rixthetrick, I'm disappointed in your characterization of my spending on audio. You are not aware of my personal finances, nor of what you see that is on loan for review vs. what I own. I would appreciate it if you refrained from attempting to judge my personal decisions on gear. Thank you.  :) 


One more comment; for the record (again, as I have said this publicly prior), I have never berated or mocked any low budget system.  Rather, I have consistently encouraged and complimented persons who I felt put together impressive low budget systems and said that I thought they would enjoy them. 

I will never forget that more than 40 years ago I started out with a Radio Shack receiver and two mismatched, naked full range drivers taken from console stereos and hooked up with lamp cord. So, please, let's not have derisive comments about my showing disdain for budget audio. 

I have, over the past 25 years, budgeted literally a line item for audio and invested into my system annually. That is one sure way to end up after many years of working at it, with something better than at first. Putting my time in learning, designing and building a specialized audio room was well worth the effort and cost. It was one of the most rewarding things I have done in the hobby, and the satisfaction of using the room regularly is quite high. I highly recommend to those with the space and inclination to give it a go. 

BTW, there is recurring insistence on this forum to the effect that the room is the most important part, that a serious audiophile needs a treated, dedicated room, etc. Nonsense; I oppose those sweeping comments, partly because I enjoyed audio in a lived in part of the house previously, and because I think they vastly overrate the impact of the room vs. the benefit of advancing the system itself. I think it would be very discouraging to the budget audiophile to see such comments, and I do not support them. Of course, a dedicated room is a bonus, but it is ridiculous to declare that one is not doing high end audio if the room is not treated with specific treatments, etc. Imo, that is a form of dismissive elitism. 

So, anyone who suggests that I'm putting down budget audio has no clue regarding my disposition.   :)
First, room acoustic is fundamental...

I think they vastly overrate the impact of the room vs. the benefit of advancing the system itself.
Second, upgrading (advancing the system) is a money pit and the root of this "elitism" that you speak about.

Third, room acoustic made my listening experiments  possible and at practically no cost a hi-Fi experience by itself...Using passive materials and also with active homemade device... I know i made it and the reward is amazing....

A remark:
Buying very good components in the scale corresponding to our purse is the first task.... But upgrading after that is a very problematic solution to the problem of the system improvement....No one can exceed his purse possibility, and most upgrades in the same rung of the scale is no more an upgrade but a "sidegrade", a useless expansive variation ....And the source of frustrations....

Then the solution to reach Hi-Fi experience cannot comes from the buying spree in "elite" new brand technology.... The solution can come and must come from the way we will embed rightfully what we already owns, that is anyway already relatively good gear if well choosen... a good amplifier or a good speakers of 20 years or 30 years ago or more are not obsolete  nor so bad that they cannot gives no more an HiFi experience...



 i call that solution the 3 embeddings of any audio system: resonance- vibrations controls in the mechanical dimension, controlling and decreasing the noise floor of the electrical grid of the audio system, of the room and of the house, and last but not least, controlling the acoustical space in a passive way with varieties of low costs materials and in an active way with simple homemade devices... All that is possible, simple, and dont cost high money.... I know that i made it.... Anyone go with his purse...

The true "elitism" and snobbery and ignorance is affirming that what i speak about, is impossible, illusory, and false...Saying only high cost gear is the key is half truths, and half truths are worse than lies....

Anyone KNOW only what he can create for himself.... I learn it the hard way for the last 7 years....

Audiophile experience is possible for all creative people at low costs....

Equating all i just say with the affirmation that  all piece of audio system are on the same level is not what i speak about at all....A Million dollars system will be better than my system but will need also to be rightfully embed to reach his potential higher S. Q....

Hi-Fi experience, naturalness of musical timbre, holographic imaging, dynamic, etc are all possible with a low cost good system, modulo the rightfull embeddings.... 
In just 5 second google search anybody can educate itself....

I will  add that the 2 other embeddings will impact critically the S.Q. in a different way than the acoustical controls or uncontrols but nonetheless in a very audible way....The electrical grid of the house and his noise floor is the sea where float the audio system... Not controlling this sea is opening the gates of distorsions hell.... :) Same for the importance of the resonance underestimated controls....

This not adocating for some disparate "tweaks" , my rant is advocating for a "method" accessible to anyone... The beginning is stating clearly the problem at the root of an audio experience and experiment....

What is the more important for Hi-Fi experience?

The choice between paying 2000 dollars for a speakers or 4000 dollars? Or the way to embed ANY speakers making it able to produce his utmost potential S. Q. ?

It is not difficult to answer.....Except for someone who sells speakers...Or some brand.... Etc....
