Highest frequency presnt on LPs?

Posted by thekong (A) on September 22, 2009 at 22:20:49

Hi All,

I wonder if you have any information regarding the highest frequencies that is present in commercial LPs.

I was having a discussion with some of my audio buddies, while some of them claimed LPs do contain musical signal above 40-50kHz, others (including myself) believe the frequency response could not reach much above 20kHz. I just wonder if anyone has concrete information on that.

A couple more questions related to this topic:

1. Since many of the golden recordings were from the 60s and 70s, what are the frequency limits of mics and master tapes of that vintage? I suppose if the mics could not pick up much above 20kHz, the signal wonâ€™t be present on the LPs

2. A quick check comes up with the following frequency responses of some of todayâ€™s top cartridges:

ClearAudio Gold Finger: 20-100kHz
VDH Colibri: 5-65kHz
Lyra Titan i: 10-50kHz
Ortofon Windfeld: 10-80kHz
Denon 103R: 20-45kHz

They all claimed frequency response of way over 20kHz, but all of them didn't show any +/- db figure. Also, I am not sure how they made the measurement; from a testing LP or something else!

TIA

Michael

LPs can go to at least 30kHz - Rob Doorack 05:50:13 09/23/09 (5)
