The Rolling Stones plan to sell high-quality downloads of their first 27 records for the first time online.
From CNNSatisfaction! Rolling Stones selling HD catalog online
While I'm looking forward to Get Yer Ya-Ya's Out! & Let It Bleed, I'm a little skeptical: Why convert the original DSD files to 176.4 or 88.2?
How else will you be able to download and play them? DSD64 (SACD) don't play on any commercial DACs natively per se. They need to be converted to PCM, and 24/176.4 is about the equivalent resolution if you do the math. Plus, the DSD files themselves are not available except protected in SACD form. My infamous approach of having the player (oppo, Sony, etc) do the conversion and then use an HDMi de-embedder is a poor man's solution...as the player machine is not the greatest converter in the world. The Weiss Saracon conversion tools used on the Stones project is much more sophisticated.
I don't have a problem with someone converting the DSD stream for me (since I don't have the gear to do it), I'm questioning the decision to go to an 88.2 or 176.4 kHz sampling rate.
as opposed to? They are integer multiples, way better than 96 or 192.
Mike, I'm not sure what you mean by "it's all math". Sample rate conversions that are NOT based on integer multiples (DSD is 64 x 44k) can have artifacts in the conversion that show up as image smearing, ringing, etc. The conversion (AARC) would have to use different clock timings, etc. Yes, SRC's like Weiss and Izotope can do a great job, but why do the extra work and risk it? And also...why do you care? If your DAC does 96k it'll do 88.2k just fine, and same for a 24/192k DAC doing 24/176.4k. In fact, one would argue that a 24/192k DAC might even play better at the slightly lower sample rate, as 24/192 may be pushing it.
