But to move towards when we can carry out such survey properly, anyone have a list of DSD recordings which are both musical and have significant supersonic energy?

Telarc SACD-60616
Telarc SACD-60601

Long live Renner and especially Bishop.

There are more titles, mostly Telarc.

I much prefer the TELARC sound before they went over to DSD. Won't touch any of their DSD ones - 'Desperately Squashed Dynamics'.

To me, their DSD recordings dated about 2003 - 2006 sound very natural. Most close to the sound I know from concert halls - to me. Anyway, I do not want to argue, taste may be different.

Thanks for this Pavel.

If you analyse any more, please post.

How do you do the analysis? Do you play them on a computer with a DAW? Please excuse my naive questions.

What is the time sample analysed? [edit] Oops! I see it is 16K @ 96kHz ie 167ms. Any reason why you chose this 167ms period? [/edit]

I prefer DXD to the castrated monobit DSD. But i'm in the minority and DSD is gaining popularity to keep cheating salami-filled audiophools ears.
Telstar, if you know of any DXDs with musical material and also significant supersonics please post the disc reference and any measurements you may do.

Richard, analog output of SACD players were digitized, mostly Marantz SA7001, but the 1st plot (Ravel) was Onkyo DV-SP503 universal player. USB sound cards behind analog output of players, sampling 96kHz/16bit and 96kHz/24bit (for these spectra it does not make much difference if 16bit or 24bit A/D). Some of the plots are quite old, like 6 years, and I do not have the exact setting (window length etc.) recorded.

Anyway, it is quite easy to sort recordings regarding spectral content above 22kHz.
 
So Scott, you prefer microphones with audio FLAWS instead? '-)

If you read the two part series in Linear Audio, you'll see the real contribution Scott has made to doing the electronics in condenser mikes correctly. I think Jan sent you copies, it's worth studying and learning- some of it is very subtle, but anyone who wants to understand how to do it right will immediately grasp some fundamental issues which are often glossed over in commercial designs.
 
Scott did a good job. No more than I have done over the years with microphones, however. I don't see any breakthroughs here.
As far as mike diameter is concerned, 1/2'' is OK as far as noise. At least George Quellet, Mark Levinson, the Grateful Dead, John Meyer, Crystal Clear, etc found B&K 1/2'' acceptable, ESPECIALLY when I got B&K to upgrade their input resistor in 1974. Since then, they have been about 6 dB better in portions of the spectrum.
The VERY IDEA, however, that SY recorded successfully with a 1/4" B&K, except for a specific test, is absurd, because they ARE too noisy. They have to be, because of the limitations in the capsule output and the very low capacitance of the capsule. A real headache!
Now where does this leave us? YES, these 1/2'' B&K mikes can be boring, many claim it to be, BUT that is its SIGNATURE, and I defy you to tell me exactly what makes it so.
Other mikes, many good ones, are preferred because they have ADDED characteristics that make them useful, like a bumped up mid hi end, directionality, PERSONALITY.
Many popular singers DEMAND that their favorite mike be used to record them, sometimes they own them and bring them to the recording session. So where is the 'objectivity' here?

That's part of the problem and one reason why I stopped using them and (at the time) went back to modified C-37s. But the noise wasn't terrible considering the media available then (pre-digital, I used Ampex 351) and the noise level inherent in live venues (I didn't do much studio work). The main problem was the overall sound, which I couldn't get past; this is not music reproduction, it's music production. Perhaps a more skilled recordist could have made things sound livelier and warmer, but I couldn't, whereas using the Sonys (for all their flaws), I could get a pretty realistic capture of the events.

Your point about musicians wanting certain sounds is absolutely correct- music production is a very subjective thing.
