What's the frequency response of vinyl?

With the proper turntable set up, vinyl yields better bass than most CD set ups. For instance, my old VPI HW19 MkIII with and ET2 arm and an AT33PTG cartridge - nothing on the cutting edge have you - regularly beats the snot out of my Parasound C/BD 2000 transport AES/EBU connected Mark Levinson No.36 from top to bottom and especially on the bottom end. My CD setup sounds good, but I really like vinyl better at my house.

The bass response of vinyl is beyond what you're capable of hearing so you need not worry for your purposes. There are some practical difficulties in recording very low frequencies because of the size of the vibrations on the record groove. It could literally bounce the stylus out of the groove. The greater limitation will be your turntable and what limitation the recording engineer put on the recording, rather than the record itself. Actually, as an aside, record warp will produce a frequency around 8 HZ. You won't hear it but it can cause damage to your system.

Oh how nice it would be for it to be that simple!
