Voicing an amplifier: general discussion

The most likely reason you would need to repeat something is because its mere propaganda and you're afraid it didn't stick the first time.

The plural of mantra isn't evidence.
Abraxalito, you dissappoint me, I expected better arguments from you 🙁

What I repeated in that post is not propaganda, if you had read it you would have noticed I was not even repeating a statement 😛 , I was simply (again) suggesting a test.


Do you want to apply for it?

Yes or no?
 
Well, to begin with there is no real 3D "presentation" or whatever you call it because our limited technology provides us with the poorest means: just 2 channels, in 2 fixed positions, to represent the incredibly complex 3D field in an orchestra playing live in a ... stage
Why it happens is that our hearing systems have evolved to make sense of echos, reverberations; it is not the phase information from the direct sound of the recorded instrument or sound alone, it is the combining of that with the indirect sound, in the recording space, which does get picked up by the microphones - and your brain unravels that, to work out "what was going on". As an example, a musical production with the orchestra and chorus in a large space, but you can "hear" that the soloist is in a small recording booth, completely disconnected from the rest of the sound - the echos, even though in a space prepared to minimise that artifact, are still enough to give it away.

This of course can only happen if that indirect sound in the recording space is faithfully reproduced, not submerged in noise, or mangled by other distortion mechanisms - the better the listener to the replay can make out the information, conveyed by the sound bouncing around before hitting the mic's, the more the sense of a convincing soundstage is formed.

Even totally manipulated recordings work - the "fake" reverb does make sense, and gigantic, empty spaces form behind the sounds in some productions, because that's how it computes to the ears - but, again, only if the replay is good enough ...

No one knows how the "totally manipulated recordings" should sound, in fact. There is no reference. If you use the "totally manipulated recordings" to evaluate your audio system, you mostly probably want to make them sound "polite" and "pleasing" to your ears. This has nothing in common with "high fidelity" in sound reproduction and you may easily prefer a piece of audio system garbage.
 
The effect is that all the sounds in such a production exist in their own space, Michael Jackson's efforts are a good litmus: multiple sound elements all co-existing, yet each occupy their own place on the soundstage, and you, the listener, can audibly isolate each with ease. Something like listening to a band of 12 or so musicians, and being able to focus on, "see" a particular member of the band as having a distinct identity, place separate from the others.

If the system does the manipulated recordings well, then it is also excellent with the real thing, such as the above band - a good cross-check that you're hearing a decent reproduction.

The sound is most definitely "pleasing" - but "polite" is the last word one would use. Intense, overwhelming, urgent, a sense of energy and drive are the sort of terms more applicable ...
 
That's exactly what's wrong in your thesis.

Amplifiers do NOT modify soundstage which is something already embeddeed in the recording ... or as I also mentioned (and you conveniently choose to ignore) a live feed.

But it's EASY to test.

As I said (why do I need to REPEAT this?) :in a sound system chain insert a few competent amplifiers (behind a curtain , don't cheat 😉 ), switch them in at random and try to pick which soundstage is which 😉
By ear, of course 😉

This is silly, really , i guess you must have read this somewhere, Stereo Review is my guess ..

You should get out more, never heard of the soundstage knob .... 😀

Where do you think the concept comes from?

That spatial position is represented in 99% recordings just by different settings of a panpot if each instrument is close miked (which was my example) or in, say, a gifted 1% (or much less) the volume difference plus some true phase difference, *if* the live orchestra (which can be as small as a string quartet or a sax/piano duo) is picked up with a single pair of microphones, arranged in one of the classic settings.

Including binaural or artificial head recordings.

In any of those cases, either the standard "fake" one or the very few direct recordings, the spatial information, the soundstage, gets embedded in the recording.

No amplifier, which works with signals at the speed of light can change that.

Even if it did introduce uneven delays (which *would* thus affect "space"), we can't perceive the micro or nano seconds involved.

To boot, the gross difference in soundstage stated by some reviewers would involve timing differences measured thousand or million times longer delays, because they should be measurable in milliseconds ..... where are they?

Even worse, such differences should be selectively applied at some parts of the music and not to others, to create a difference in timing able to affect soundstage in some way.

In fact, by sticking to such outrageous and impossible to demonstrate statements, they are shooting their own foot.

Don't waste time on us who have a firm grasp on how things work, based on solid knowledge and experience, go try convince some gullible unsophisticated customers that they should spend their hard earned money on esoteric products.

Practice which I don't condemn per se, there's people for everything ... including Homeopathy, Natural Healing, Astrology and a thousand other Human Interests of the same kind.

Taking that WC lost hard , huh Buddy ...🙄



:rofl:
 
And guess why it's never going to happen ...



A nice little income stream ...

Probably because after what he claims are thousands of failures and not a single winner it gets a little old.

Edit: I find it interesting that people keep saying the test is flawed, and then in the next breath, type out two paragraphs about how it should be able to be passed easily.

You understood it the wrong way 😛

I read this amplifier soundstage modification silliness right here, specially in this already 600 post thread 😀

And of course I state that the soundstage knob does NOT exist in an amplifier, in fact that the amplifier does NOT influence it, knobs or not, why would you say otherwise? 😕

The experiment I suggested is a classic "blind test" , nothing new here, to prove/disprove that 😉

Okay, so I guess I was the only one who noted the irony of using the very same kind of subjective criteria to choose their preferred amp while at the same time eschewing the notion of subjectively choosing their amp's audio output
You are committing a category error. The electronic function of a hi-fi amplifier is to reproduce sound. There are objective criteria for that.

An amplifier may also play a role as a piece of furniture - I understand that some audiophiles display their system. That is a subjective matter of taste. Some like big glowing valves. Some like huge heatsinks. For bought items there is also things like long-term support and brand loyalty.

And resale value .... 🙂

That's really the only thing I preferred about my old separates..I sold them for about 75% of what I paid...the same can not be said about A/V receivers, as once their feature set lags behind the times (HDMI for example) they become almost un-sellable.

Aside from that though, there's absolutely no audible difference between a proper A/V receiver and a boutique pre/pro + amplifier, because if you could reliably say so, then it wouldn't be a contentious subject.

So, the whole idea of voicing something which by design has no voice becomes kinda goofball.
