I haven't ever heard electrostatics, but I did once get to hear some ribbon loudspeakers, which have some aspects in common as regards how you set them up in a room. They were Apogees (either Centaurs or Centaur Minors, I forget), and made some very nice sounds. However, like (most) Martin-Logans, their cone woofer/sub was part of the same cabinet as the mid/tweeter, which doesn't necessarily always make for perfect placement of either element.
If you want proper massless drivers, look up ionophone/plasma speakers... and all the problems that come with trying to operate them effectively while staying sane and un-electrocuted.
I reckon this lack of answers means that what I'm asking is not possible....
A good start:
It's as valid a speaker design as any. My experience is that they need a big room and lots of space around them. They don't sound good against a wall or in a corner. Often best served by a high-current amp. Probably need a sub to get that bottom octave, though M-L does make some nice hybrids.
Check other manufacturers (JansZen, Sound Lab) and read some reviews. No substitute for hearing a pair yourself.
Close foobar :-). Settings are saved automatically :-)
But more seriously - go to %appdata%\Roaming\foobar2000\Config and copy it's content. Or even copy whole "foobar2000" subfolder. You will then keep your layout, database and components.
It does sound like the problem is line related.
If you reinstalled the mounting screws, they would have transmitted the vibration past the rubber pad.
My suggestion would be to isometrically mount the noisy transformer. If it employs mounting screws, obtain some rubber grommets from the hardware store. Grommets have 4 dimensions- the inner diameter that accepts the mounting screw, the overall outer diameter, the hole size in which it fits, and the material thickness that it can accommodate.
You will need some longer mounting screws as well as 2 washers for each screw and a self locking nut for each screw.
Select a grommet, you don't need a big one, maybe the outside diameter might be 1.5cm. Measure the hole size it needs and select a drill that is the same diameter. You will use this drill to drill out the mounting holes in the chassis for the transformer (assuming there is room; the examples that I have seen do have room). Having done that, install the grommets. Install a washer on a screw, feed the screw through the grommet from below, install the second washer on top, so it is between the grommet and transformer resting on top, then install the self locking nut to hold the transformer in place. You don't want it particularly tight, but it should be snug. Do this for the other mounting screw as well.
If this is done right, the transformer will be mechanically isolated from it mounting and thus unable to transmit vibration to the chassis.
I just did an exhaustive search of the web for any sort of hard science on electrostatic speakers, and except for a few blogs of variable quality, the only thing I consistently hit was an advertising blurb from Martin-Logan. For obvious reasons, I don't think their take on the subject is unbiased.
What I'm curious about is whether there has been a decent write-up anywhere talking about some of the claims made about electrostatics, and any basis in fact associated with those claims. One thing which comes up with maddening regularity is the so-called "massless" nature of the driver. Obviously, this is pure hype because even the thinnest, most flimsy LDPE or Mylar films have a density of tens to hundreds of times that of normal atmospheric air. Combined with the fact that the force behind the ESL "motor" is lower than that of a typical electrodynamic driver, some of the claims about the system seem questionable. There's no doubt that a good speaker can be made with the technology, but the hype seems to over-reach the actuality.
It seems that so many people repeat the myths, any research, design or evaluation information has been buried under them. Does anyone know of a good unbiased treatise on electrostatics which addresses some of the pros as well as cons of the type, and backs them up with measurements and logic?
Rollin's post about resampling ruining gaplessness has been bothering me ever since reading it. I implemented the extrapolation used in Vorbis and Opus to SRC resampler v1.0.2 and it appears to perform quite well. At least those sample files from the linked post can be resampled without glitches.
Edit: added two comparison screenshots of the transition position. One is resampled with SoX using hiqhest quality and the other one is SRC with extrapolation.

ok, i have tested again (flac image this time) and set libflac encoder + decoder and the result is still accurate.

no, i have tested the encoders. no differences between libflac and cuetools on my side. btw it was a wav image that i had split up. my mistake.
