Spectrogram Help: Poulenc's Organ Concerto

[mansr]

The 16 kHz tone is likely from a CRT as those were still common it 2001. It could also be something else.

 

The noise is from a sigma-delta modulator somewhere in the production chain. Could be the recording ADC, or perhaps this is a conversion from the SACD release. That sounds pointless, but these things do happen.

I just need to decide whether the high res. download would provide a sonic advantage over my CD rip.

I'd say there's no reason to buy this again. The spectrogram shows a little content above 22 kHz, but it will mostly be drowned out by that noise (not that either is audible). The exception would be if the CD sounds bad in some way due to a shoddy down-conversion. I wouldn't expect that from Linn though.
