Metal speaker stands V wooden stands.

But you are talking measurements..

The ear picks up influences that can't be measured, as yet. Can you measure soundstage depth? You can certainly hear it, or the lack of.

All figments of your imagination Al.

Must be if you can't measure it?? Lol

To be fair, I started laughing at "Wireworld"

Wouldn't a piece of 2 x 2, and measured for height do the same job?

I disagree. The recorded soundstage is vastly affected by amplifier/preamplifier performance.

Have you never listened to an amplifier that sounds 'flat' or 2D, then on another occasion with a different (better) amplifier marveled at the depth from the same recordings.
I rather think you have. Now measure it.

the thing is we are not talking about 'qualities in sound'.

A recording is simply a set of instructions to vary voltage over time. That voltage change is sent down the speaker cable and causes a magnet to oscillate a cone to produce pressure waves. Which our brains then interpret as music.

That's not music traveling down the speaker cables, it's an electrical current. It only has frequency, magnitude and phase, same as any other electrical current.

All those parameters can be measured to the finest degree.

Suggesting that there are other, unknown parameters to an electrical current is a massive claim. It would mean that the entire basis of physics is wrong. if someone was able to demonstrate that was true they would be up there with Newton and Einstein. Nobel Prizes would be awarded. Everything we think we know would have to be scrapped and start from scratch.

I don't think people who casually say with regards to sound reproduction that 'We can't measure everything' don't realise the enormity of that claim and how desperately unlikely it is to be true.

If there were any substance to it at all then Physicists would be all over hi-fi, trying to make a name for themselves. But they show zero interest. Why do you think that is?

What sort of things Macca ? 

My guess is that language is causing each to object to the other on the basis of something they are not actually meaning to say.

I think it rather likely that all the things we can measure in electronics have been measured. But are they all commonly measured? How those measurements relate to things like 3D sound and why one component contributes well to it and another does not, have not been well identified. The factors are probably multiple and interactively complex and way beyond what ASR is able to contemplate or analyse, perhaps even able to measure.

I find it interesting how much argument among DIYAudio members operating in the area of hard circuit design and measurements disagree for what is important and why even at a circuit level.

So for me it is not something metaphysical or unknown at an essential level, it is the significance, interaction, and complexities that have not been identified in such a way to measure them. So, in the complex interactive world it *functions* as a mystery and currently must function so until someone identifies it.

OTOH: there are aspects of electronic design that are growing over time. At one point in history I understand that they did not know to measure certain aspects of crossover design in regards to phase and impedance. Then John Bau started measuring phase linearity and designing a crossover for that. Him identifying the importance of that influenced other design work.

In the digital world, my suspicion is that the ground plane in circuit common between components has a much bigger effect on the sound output than has been identified or generally acknowledged. Do I know enough to say why or how? No. But I keep seeing changes to digital components affecting the sound in a HiFi system like analog does. Does that make any sense? No. But since it keeps happening and is repeatable and noticeable, there must be an explanation. Do I religiously hold to the idea that therefore it must be imagined? No, just unidentified. Is it my role in life to find and measure the proof? No, but that doesn’t keep me from noticing the issue.

One should take care to identify contaminating factors such as bias or if multiple things were changed at the same time even inadvertantly. But too many people like to declare others as imagining things and against the laws of physics when it's actually the above case.

Just have a look in your favourite shed and make some wooden jobbies out of wooden off-cuts. Mine work a treat.

yes I largely agree. We can measure every individual aspect but how they interact can be very complex. No argument from me there. But feet on a DAC? No. 

It's a garage in my case Andrew. Wooden stands ( hollow and fillable with sand etc. ) on the way 

well it is a hi-fi forum, what else are we going to talk about?

But it goes against the grain...

I wouldn't beleaf it if I were yew.
