Correct, and his work went on to define what harmonic relationships were audibly pleasing. I found his treatise scholarly and his delivery of the information just kindly enough so that he wouldn't be challenged as a 'know-it-all.' IIRC his great Class-A amp boards were making a musical difference as far back as the 1970's.

What I'm saying, and I think Mike Gray is also saying, is that I doubt THAT'S what's up there with the older beloved recordings, because mics, transformers and tape couldn't pass those frequencies. I also forgot to mention that most LP cutting guys low-passed well into audible frequencies to save their cutterheads from blowing out with intense upper-octaves energy. Remember that the RIAA boosts upper treble frequencies by large amounts, as do all electrical pre-emphasis curves, to one degree or another. -- Tom Fine ----- Original Message ----- From: "Mark Durenberger" <[log in to unmask]> To: <[log in to unmask]> Sent: Tuesday, March 25, 2014 9:27 AM Subject: Re: [ARSCLIST] Fwd: [ARSCLIST] "Why Vinyl Is the Only Worthwhile Way to Own Music" > One refers to Rupert Neve's thoughts on why coherent super-audible > response is useful if not necessary. > > Someone else on the list may know where his paper was delivered...I have > the audio of his remarks for anyone interested. > > > Regards, > > Mark Durenberger, CPBE > > > -----Original Message----- > From: Gray, Mike > Sent: Tuesday, March 25, 2014 8:03 AM > To: [log in to unmask] > Subject: Re: [ARSCLIST] Fwd: [ARSCLIST] "Why Vinyl Is the Only Worthwhile > Way to Own Music" > > Seconding Tom's comments - what exactly *is* that energy above 20kHz? > > Mike >
