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

...an absurdvation for one that doesn't use or even have a pre-amp....

I can turn my volume to max....and nothing....even with my low-rent IC's.

AB SS amps....nothing pedigree....SS 'pro' Eqs'....

The RTA sez their's a 'noise floor'....but I can't hear it.

*shrug*  Maybe I'm just lucky....or in a local focal locus that allows such.

If so....no, you can't move here....*G*
Obviously I don't Dare touch anything other than 'volume'.....

One false move...*poof*

Then not only it is important to have a clean amplifier but way more important to clean the other part of the system and decrease the noise floor of the house....


Clean is then not enough "clean"..... :)

Here is the thing, some folks, do have a few extra quid. I worked my whole life. I worked HARD, I worked long hours, I saved, scremped, and did without for 45 years.

I had saved a few stereo, parts (My Mac Gear). Made quite a few speakers, through the years, and planed 38 years ago when I did my house remodel, what rooms were going to be for sound.

I have a general idea of your concepts. I agree with them wholeheartedly.

I also want to add, good, Better and BEST. I agree it doesn’t take the best of all thing, to build a GREAT sounding system. A lot of good can surely work out to Better, but the BEST, it takes better part to start with. It took a lot of the guesswork out my journey.

Here is a great example. Mac gear. WHY are the power cords, fixed in place, and have really small conductors with a copper plug. ALL their old stuff has it, and it works really well. WHY?
90-115 VAC really dirty, low voltage, all the bad things you could have.

That Mac will sound GOOD. 3/4 of the stuff that has to be done with a lesser piece of equipment to bring it up to, that standard, cost way more than the Mac did to begin with.

While I appreciate YOUR system for you, I don't have the same situation, or limitations, for me.. I did however build a "low dollar" system a few months back.  It is a good system, but it will never EVER sound as good as my main system. I don't care what I do to it.

You people are fooling yourselves in an effort to not spend money - your higher priority than actually attaining superior sound.- by promoting your belief that at best average gear will magically get you superior sound. You are completely clueless. You’re wasting your life fooling with poor methods that waste time and money. Never seen such arrogance over nonsense. You will NOT ha e anything close to SOTA, no matter how much you boast. ONLY superior systems make superior sound. Tweaking is a loser’s game, for those who have resistance to spending money but want to pretend they are doing the same as those who actually go out and get premium sound.

Simply because you work like a dog to tweak systems, you figure you are making amazing headway, catapulting the sound WAY up there. Not so. You are messing around in a small, yes small, slice of the performance spectrum and are not even touching the upper end. You typically do not qualify your posts, but boast about getting sound that can't be improved, is exemplary, etc. It's ridiculous.  :(
