Telarc spectrograms and plot spectrums

Britannia 
Elgar: “Pomp and Circumstance” Marches Nos. 1 and 4, Maxwell Davies: An Orkney Wedding, with Sunrise, Turnage: Three Screamimg Popes, MacMillan: Britannia, Britten: Sinfonia da Requiem
Donald Runnicles, Atlanta Symphony Orchestra
Stereo/Multichannel - Pure DSD
Telarc SACD-60677


























Ballet Favorites 
Erich Kunzel, Cincinnati Pops Orchestra
Stereo/Multichannel - Pure DSD
Telarc SACD-60625

















As one can see from the spectrograms and plot spectrums Britannia is true high resolution, however Ballet Favorites doesn't have much response beyond 20kHz.  Curious how the ultrasonic DSD noise is so much lower.

Both of these sound great, however Britannia is one of the most realistic SACDs I've heard yet.

Transfered it to my computer with Audacity using the analog outs.

  1. Would it be possible to test A/V receivers for direct DSD-to-analog conversion using spectral analysis? It seems to me that if this would work, it might be the only way to know.

    1. I don't know, it might require real test instruments instead of a software program. Maybe something that can measure the bit rate? Since DSD is single bit and high resolution PCM is 24 bit.

  2. In a way, it's a good sign, because Chandos has evidently decided that SACD is the best digital disc format, even if they don't want to release pure DSD. (At least it's not limited to CD!) Perhaps it's a sign that more musicians and labels will migrate into SACD. Blu-ray audio is going nowhere, as far as I can tell, so SACD remains the only high-resolution audio-only digital disc format.
