Not exactly a starting point, but interesting nonetheless : http://www.discogs.com/Villa-Lobos-Prokofiev-Leopold-Stokowski-Stadium-Symphony-Orchestra-Of-New-York-Uirapur%C3%BA-Modinha-Fro/release/3469195
Yes.
This is about how I remember Hitachi Class G amps - it was/is a decent sounding design that is very cost effective. 
One thing is certain - in nature, there is no filtering above 20 kHz ( except through distance in air - which can give us the information of the depth of the sonic image ). Reasoning is simple - if most, if not all sound is recorded and reproduced, it should mimic the real thing the closest. Ear induced IM, if it really occurs, should be exactly the same "problem" with live music - I have yet to hear of somebody complaining about any instrument that does exceeed 20 kHz to...
Hehe, that means you have yet to experience a really good turntable  - as noted before, hearing capability of pure sine tone past 10 kHz NOT required to allow one to appreciate the overall difference. HiRez, one sort or another, is coming close - and may exceed the ultimate analog is capable of in near future.
G forces would indeed be "a bit" too much. It is hard at normal RPMs for the stylus to track 100 kHz - takes extremely low effective mass models. Not a joke; Technics EPC-P100CMK4 cartridge with 0.055 mg ( about one third/fourth of anything available today ) stylus effective mass can go "flat" to 120 kHz - and does not stop there. And, although accidentally, 122 kHz bias frequency from the analog recorder has been at least once successfully transferred to the analog master...
Math doesn't add up.
Where are you from ? For Europe,  I know (of) two sound cards that do have line input, which you could feed from phono preamp. The cheaper cardhttp://www.conrad.com/ce/en/product/872990/USB-SoundBox-71?ref=listis also available in the USA under different name ( sorry, forgot it, but it looks exactly the same save for lettering and/or colour )the better and more expensive onehttp://www.terratec.de/details.php?artnr=10546#.Va5RiPntmkois more "restricted" to Europe. These are...
To everybody; the effects of current limiting , phase shift, etc caused by the pure capacitance of the electrostatic drivers in any amp are measurable/visible/audible LONG before the actual output on the scope gets into the trouble.   The only real answer would be infinite power amp - which is a practical impossibility. If one goes with feedback only from the cathode resistor ( which does not force the front end of the amp to try to compensate the frequency response...
I will scan one day the "papers" that came with this set of test disc, tape and CD. Cassette decks were top Revox machinehttp://www.hifiengine.com/manual_library/revox/b215.shtml, specially selected from the production run, sent to the "record plant", where they have been further once more calibrated by the Revox staff. Then the duplication begun - 1:1, real time, on so and so many cassette decks, until the number of copies desired had been reached. Tape used was from...
