How you can test most easily if a coaxial cable ( interconnect ) is microphonic or not ? Simply plug it into a phono input, open the volume as you would usually listen to your turntable, and tap with your finger anywhere on the cable EXCEPT the exposed centre pin on the RCA male plug on the other end of the cable. Poor ones will be instantly audible, for good ones you will have to turn up the volume by 10 dB or more before you will be able to hear anything. And you can...
1.I do not know how you got the idea that I play test tones of single frequency at full output - or why you keep on insisting on it ? I merely stated  how amps can be tested in the particular case for electrostatic amplifiers. 2. It goes to show that you have not been lately to a live concer featuring a good soprano. Yes, they ARE loud !!! In the recent recording of Bach+s Johannes Passion, the entire contents on the stage at full cry was only 3 dB louder than a - single...
It is true. It is equally true that more than half of the total capacitance is in the cable. Wasting the amplifier power, cutting the power bandwidth (as the frequency to which an amplifier can drive the load to full output without excessive distortion is correctly called ) in less than half. I will re-measure the cable removed from my Lambda Pros - I remember the total capacitance being a bit higher than 122 pF, by about 10 pF or slightly more. In a real non academic...
This is true - IN THEORY. In practice it is a "bit" different. And that bit diffferent is - legislation, in EU at least. Since a few years, esl amps above certain combination of voltage/current are banned.You can not import say Beveridge ESL speakers with built in high voltage direct drive amps anymore. Legally at least - and how you are going to smuggle the 200 kg 2 metres tall speakers trough the customs, is up to each individual. I know I am not going to try that...
That - making people wonder about stuff they never thought of - was my prime intent. Because without out of the box thinking, there would never be any progress - we would still be living in the caves. Bon nuit, Chateau 
Last time I checked I did say on which type of music this is most easily noticeable.  I never even mentioned using pure test tones in connection with esl amps - at least not in this thread. I merely stated the 4 kHz limit t for full output of the SRM1MK2 amp - above which it can no longer play at full volume. Female voices. Good and loud -  and recorded without compression. It does not sound particularly loud live - yet matching that loudness with Stax stats IS a problem...
I will answer this later today - after a wake up etc. Trouble is, it will have to be custom made - no catalog I went trough did not have anything usable off the shelf. What I did use does not satisfy safety requirements and will because of that not be shared. Although I have been using this cable for more than 30 years now.
You did NOT understand how ESL amps ( well, most of them ) work. It would start rolling off above certain frequency under open loop condition - no feedback applied - regardless of volume . At low enough volume , feedback loop can compensate for the loss - by driving the output ever harder at ever increasing frequency - but this has a definite limit. And that is usually power supply of the front end of the ESL amp. Once this is reached ( many times prior to the hard...
Yes, I did realize that I have been monopolyzing the other thread Precisely because everything that did not fit into the mold of the beliefs mutually shared got suppresed ASAP. The only difference is that the others who have not shared the same beliefs have chosen not to bother after realizing how things work on the other thread.  Just because most of the members have only three kind of cable that are relatively easy, that does not give anyone the right to say that cables...
It is programme dependant. The most affected and easily audible are LOUD FEMALE VOICES.  For this reason ( all kind of lesser equipment going "on strike"), later releases of even the likes of Barbra Streisand have been - squashed into something that can be played without the protest from most of the equipment. Taming the tigress into a pussycat in the process... two examples : ( limited by YT - it is startling difference on vynil and a good turntable )   Once you hear it...
