I surely know about the transformer, but I obviously did not understand why the transformer will alter the way an electrostatic transducer works; I mean it is still an electrostatic transducer that works (in theory) perfectly linear if no charges are moved (and if used as push-pull).
Surely thats part of it.
An original and Great solution. Thank you for sharing.

How can words describe exactly how something sounds in a particular way? That is why I believe it is best to visit and listen for oneself. Particular passages of music can be played and listened to with coaching as to what to listen for at at a particular time offset in a song.
Other than that, some people have taught themselves. The idea is play the exact same song on multiple pieces of equipment and listen for something that seems to change with each equipment substitution, without the music itself changing.
Typically use the song Black Cow from Steely Dan myself because it is well recorded more than for any other reason. If using Windows care must be taken to avoid its meddling with the sound. Also, best to turn down the software volume maybe 3dB-6dB or so to avoid any intersample over distortion. One can kind of hear how much it has to be lowed for distortion to drop a little. Windows can display the control panel volume settings for a device in dB by right clicking on the volume level display and changing the display scale.
I also tend to listen at a pretty low volume level, but Jam listens at a much higher level. One has to find what works best for them.

The amplifier doesn't see the panel, it sees the whole setup of tranformer and delay line.
Yes, and what sounds best for them
I'm just interested how people go about it and how it's different for different people. Regards accuracy, Richard's method seems the best to me so far.
With a white flag.
If I remember well, the topic was about voltage VS current and electrostatic VS electrodynamic ?
My point was that, trying to understand the difference, if we move the two kind of speakers at DC, it is obvious that the force in action is Voltage for an electrostatic (apart the parasitic current to charge the capacitance) and current in an electrodynamic (coil made of a supraconductor, 0 Ohm).
If i consider all the domains involved, electric, mechanic and acoustic, in order to play music with this crap and their inherent parasitic behaviors, the only simple conclusion i can reach after this is that the creator of the laws of physics dislike high fidelity.

Although we are all different (like snowflakes
) there is a master goal we’re aiming for......reality in playback. it’s not hard to imagine everyone without a disability should (with a little effort) be able to differentiate between what sounds as if they were at a live production (whether it’s true to original production or not) and just a played back recording. Granted there needs to be a little imagination involved to get dialed in to that point but once there shouldn’t everyone be able to hear it?And I’ve heard jc mention he uses recorded voice to dial in his systems also.
I pay a lot of attention to vocals and inflection therein and find usually if you can get the vocals right everything else falls into place.
How do I know my version of right is correct? By sampling different sources of that artists recorded voice from interviews to live performances.....most famous artists usually demand high standards for recording and their fame makes finding interview samples easy.
Having recorded a lot of live music also helps in knowing the difference.
In the end if you can crank it up to live levels and it still sounds good it’s going to sound ‘better’ at normal listening levels also (in my experience anyhow ymmv)
This is true, to a lesser extent for pure electronics, and perhaps explains why some EEs (read my lips ;-) tend to take themselves for God when they have managed to obtain some approximate results.
About as much as with a capacitor, so, no.
The artifacts created by a servo are small, but measurable and simmable.
The artifacts created by a capacitor with zero volts across it are by necessity zero. So it is a matter of size after all.

And that's where you're mixing your goals with others.
A few thoughts -
- nothing ever sounds like "reality" (whatever that is). A lot of people just want to *like* the way it sounds. If it's live music you refer to then the room will never sound the same. Some are happy to struggle with that, others just sit back and enjoy.
- even if live, what sort of live? Concert halls, clubs and festivals are very different. For example, from a way off most festivals are mono yet with no reverberation.
- a lot of music has no live component - completely studio based. What's reality then?
- a lot of music does not even have an acoustic component - all electronic music for example.
Now, you may well not want to listen to that, and that's cool. As long as your subjective experience is good, then great. And I think we are all happy hearing about your (and others!) journey to your subjective nirvana - after all we may pick up some useful stuff along the way!
It's only when someone says, or implies, that their personal subjective world is somehow right, or better, that things kick off a bit.
Do-you authorize-me to think aloud ?
- What should be the need of this capacitor if 0 V across it ?
- As this capacitor is used here in a bridge, is its impedance constant with frequency ? (the high capacitance value usually needed here implies an electrolytic one).
- Is the lifetime of such a capacitor equals the one of an integrated circuit with all its crap around ?
- As you pointed, can I believe my wife when she says to me, with indulgence, that size does not matter ?
Gpauk, I suppose it is very genre and style specific....but within those constraints if you were after a live sound, any room can be made to sound as such with the right tools and motivation.
It seems a lot of people are ok with ‘good enough’ when there is so much better to be had with a little effort. Nothing wrong with vanilla I suppose but it seems as though the people that strive for/prefer ‘better’ are labeled as audiophiles and dismissed as fools!

I'm not so sure, he/she/it allowed us to get remarkably close by flapping a sheet of paper/tin foil around, never ceases to amaze me.
If there is 0V across it, would there be any current?
If there would be constant voltage, what would be the frequency response, hint Walker's equation.

Funny, I was thinking about it with exactly the same words, but I attributed our little successes to the human ingenuity to fight against adversity.
Just a way to see the glass half empty or half full ;-)
Do you mean accuracy like Richard means it?Although we are all different (like snowflakes
I feel everyone shares in the same reality....whether you like it or not is up to the individual. this (like it or not)might be where denial enters the picture and interpretations get distorted to fit personal needs.
now if you want to start getting into Schroeder cats and trees falling in the woods, etc .....then reality goes to a different level.
just how I see it......the taste for accurate sound cannot be a lot different than reality......and reality really shouldn't have too many definitions.
