Makes no sense to me that you ask for some tests in my audio system when I have to prove you or any one else nothing at all.
Dear Raul, of course you have no obligation to prove to me, or anyone else, it is your system after all! Only that you always claimed to be willing to learn that I thought you would be interested in a simple test, which would take you less time to carry out than writing the response, to prove to YOURSELF whether airborne feedback was causing any problem in your system.
Well, after all those distortion talks, I suppose it feels better living in the comfort of the pipe dream believing all is well in your system, than to venture into the potential horror of finding out airborne feedback is indeed causing distortions. The true horror was, of course, the claimed highly trained ears couldn’t even detect that!
""" I suppose if you play the Telarc 1812 at 109db peak, you probably could feel the pressure on your chest. """
that stament you made it confirm you understand it because in my today enviroment I don’t feel the pressure in my chest ! ! !
That is interesting, playing Telarc 1812 at 109db peak (yes, those cannon shots) without feeling the pressure on your chest! That really gives me a better picture regarding the performance of your system, thank you! Yes, you are right, I don’t have that in my system, I can’t imagine that, but then, I also don’t want that !
Interesting enough, you posted the following in another thread:
Dear @enginedr1960: Yes, always near field live MUSIC is the perfect REFERENCE for audiophiles…..

Do you really believe your chest wouldn’t feel the pressure if you were standing close to those live cannon shorts during the recording of the Telarc 1812?
If you think the talk of airborne feedback is nonsense, then please take a look at what a true expert, Mr J Carr, who you like to quote to support your position on the FR64S, had to say (emphasis by capitalization by me) :
BTW, I wouldn’t recommend combining the phono preamp together with the power amp. THE SOUND OF THE TURNTABLE IS TOO MUCH AFFECTED BY VIBRATIONS TRANSMITTED THROUGH THE AIR AND GROUND. FOR TOP PERFORMANCE THE TURNTABLE SHOULD BE IN A SEPARATE ROOM/CLOSET ISOLATED FROM THE VIBRATIONS AND AIR PRESSURE FROM THE LOUDSPEAKERS. If you were to go with a combination phono/preamp/power amp together with the turntable in an isolated room, the speaker cables would likely need to be v-e-r-y long.

Of course, if you are happy with the current performance of your system, then by all means enjoy it!
Best regards,
