Audio nonsense

"Aren’t you late for that book burning, would hate for you to miss it…"

And that's what this is all about. In a nutshell.

+ 1 million.

It could improve the sound of some amplifier/speaker combinations, but is probably not necessary in most

in some instances it will actually be worse - some manufacturers leave have left zobel networks off their amps on purpose. Certainly no panacea.

@pesky_wabbit ,

 belief can indeed impair sound judgement

...applies to too much of human experience, stitched into the DNA , and never fails to ruin get-togethers' of all sorts...

Tempests' in teapots are happening everywhere all the time; all one needs to do is turn down the heat of the stove.
Audio reproduction and the space, that within that space, the equipment within and employed for playback, the receiving ears (of varied physical conditions) and that immediately about them and location within given space...

...and then the mind that interprets the neural energy from the ears, annnnd that whole ball of mush coughs a response....

"Sounds' good, But...."

To wit: "It's a wonder we can feed ourselves...."  ( Thanks, Bob...)

The only day I expect that we will finally agree upon One Given Thing...

...is the day the comet is just about to cash the planetary ticket.

"We're all righteously screwed!"

Yup.

Now....about that Black Sabbath LP.... 

@pesky_wabbit oh man! A little deep in the thread, but I LOVED my portable Sony Minidisc. Still have it as a matter of fact! Great little unit, excellent sound as well! It’s one of those dinosaur era gadgets that will be in my keepsakes as long as I exist. Now, I just may go break that thing out and try it with some REAL headphones! 
 

Regarding the post as a whole, I think there are a ton of products out there that are pure money grabs. It just is what it is.

@waytoomuchstuff The absoluteness of their belief systems are a bit stunning at times.

Subscribing to known and accepted maths and physics that have accumulated over the history of human thought is not a belief system. While this goes back millennia, I do note that it was as recently as 976 AD that the concept of zero was used by a Persian chap, and Fibonnaci introduced this zero thing to Europe in 1202.

Any observation ("stunning") relying on an incorrect assertion that this is a belief system is irrelevant. Something called the Renaissance happened.

Incremental advancements are happening continuously. For example, engineers are working on Class D technology that is far superior than just a few years ago - and Class D has been around for well over half a century (I'm happy to be corrected on that, guessing a bit)..

It is known by diligent and humble engineers that further advancements will continue to be made - possibly not quite sure what they will be, but that’s pretty exciting, innit?

Measurement technology and a knowledge of relevant metrics has advanced substantially, and will probably continue to do so.

So, charge on Bumble Bees!! Trying using some snake oil to lubricate those slide rules?

Particularly when you see them mock and ridicule both the product and the consumer

Uh huh.
