There are many techniques for getting a loud mix. That works on CDs but you cannot do that with vinyl.
afraid you're very wrong about anything above 17kHz on vinyl being surface noise, it's simply not true. The recording and tracking ability of vinyl is well over 50kHz, possibly right up to 100kHz.
Like I said before, we may not be able to hear much above 50kHz, but we can still detect those frequencies
You certainly can over compress vinyl to get the equivalent of the loudness wars. It was done on 45 rpm singles back in the day.
Frequencies above 17kHz can be cut into vinyl, and turntables can certainly track them... but after a couple of plays, these frequencies would turn to mush because the modulations would be so fine the physical contact between needle and groove would destroy them. LP record mastering involves a low pass filter applied as the lacquer master is being cut that eliminates these high frequencies to guarantee that the record wouldn't wear out prematurely.
Blind listening tests have shown that although people may be able to detect super audible frequencies as sound pressure if the volume is high enough, it doesn't add anything to music. In fact, they polled people to listen to two samples.... one a full frequency response recording, and the other with the whole top octave- everything above 10kHz- lopped off. A large majority of people said that the two samples were of equal sound quality.
20kHz is more than enough to contain the fundamentals of any acoustic musical instrument along with its significant harmonics. Take an LP record, perform a low pass filter to isolate everything above 20kHz and pitch it down into the audible spectrum so you can hear what's up there. I guarantee you, it won't be pretty.
