Dear Amir
My experience with 5.6 MHz DSD is that it has allowed me to record the most vivid recordings to date. 5.6 MHz DSD seems more open than Hi Rez PCM, but as I do not "split the signal" when I record, as in recording one signal in two separate formats, I have nothing to compare my 5.6 MHz masters to.
I am soon going to put out DSD files of an analog recording I did in Japan of a piano performance of J. S. Bach's Goldberg Variations. Since the original is analog tape, I did both 176.4 PCM and 5.6 MHz DSD versions. My feeling in this case, is that, there seems to be less difference (if any) between the two, but I think that is because of the limits of the analog tape, (if you can believe that....)
Basically 176.4 kHz recording should, in theory, result in a frequency response of around 80kHz. Analog tape never got that high;
5.6 MHz DSD has the potential for an even higher F-response.
NOW, going from 5.6 Mhz to 176.4 kHz (basically downsampling) for editing and CD release production, is a necessary evil. I am not able to record at 352.8 kHz or 384 kHz, but I believe that sonically, those sampling rates would be the PCM equivalents of 5.6 Mhz (if that makes any sense). Now that people are able to experience 5.6 MHz DSD on their systems, I am happy to be able to make my DSD files available.
In the past, I put out an SACD sampler called
MAonSA and all the sources were originally PCM. There has been much interest in this disc since I put it out, probably for a number of reasons. Everything was converted with very Hi End PRO DCS gear and with a specially custom made 25 pin D-sub connector that Crystal Cable made for the project. Of other interest is the fact that I put different music on the CD layer so this disc is actually more than 3 hours long, if you can play both layers, of course!
As far as going back to DSD from PCM after editing....... I would say that "on the fly" is not the way to do it, but one should first convert to a new file and then audition the results. Ultimately, in my opinion, any type of conversion, is an alteration of the original, so there is obviously a chance of things changing... There are other variables such as the quality of your HDD or computer's interface as well as the speed of its processor.
I wonder if this gibberish helps....
Sonically Yours.......
