DSD or 192/24 download question


#1

So this is a newbie question. I was thinking of downloading a DSD file from Acoustic Sounds… but I’m not sure how to go about playing it on the Directstream Dac with my Mac Mini (usb output).

Right now I’m using Decibel, and it does have a option under preferences to “enable DOP (DSD over PCM).” Does that mean Decibel will be able to play a DSD file I download from Acoustic Sounds just by dropping the file into the Decibel playlist window?

I’m guessing I’ll need some other software like JRiver, Audirvana, or Bit Perfect (with the DSD add on software) to play the DSD file.

And my second question, would it be better not to complicate things… and just buy a 192/24 AIFF file of the music, and let the Directstream do its own DSD thing to the music?

The music in question is the Thriller DSD download at Acoustic Sounds, which is supposedly the same as the SA-CD master. The HDTracks version is 176kHz/24 file and may or may not be from the same source. In all fairness, this album has always sounded pretty darn good in any format, so I may just be splitting hairs.

Paul has a write up on how to build a media server on a mac mini

I don’t use MAC, but I understand DoP is the way to send DSD to the DirectStream via USB. It sounds quite nice on my Windows based Media PC.

As for where/what to buy - I’ve posted this before, be wary of where you purchase your music from; make sure they can describe the provenance of their HD file. HDTracks (and some others from what I’ve heard) has been known to just sell upsampled Redbook recordings for example. And when I’ve asked them about where some recordings come from, I get a (virtual) shrug and response like “whatever the record companies give us”.

Sorry I don’t know specifics about Acoustic Sounds. I don’t believe I’ve purchased from them yet and run the tracks through a spectral analizer to see what the frequencies look like. On some albums (like Van Halens Fair Warning) you can clearly see a hard 22k cut off - which is infuriating that you’re paying a premium for a CD upsample.

HD Digital music is still really in it’s infancy, even though it really started with SACD. Give it time, and I’m sure it will get better. Till then, buyer beware - do your research.

DoP is indeed the way to go.

Acoustic Sounds takes a great deal of care to have accurate info about their recordings - they are what they say they are. But just because something was recorded and processed with a specific technology doesn’t mean it’s definitely good (or bad.) I do a lot of shopping at Acoustic Sounds (and other places.)

All right, thanks for the answers guys. I guess I’ll just have to purchase the DSD download, and find out if it plays (in Decibel) by dropping it into the playlist window. If it doesn’t play thru Decibel, I guess I’ll just wait to play it with some different software down the road.

I plan on doing the free test drives of the other major software programs out there eventually. Right now, I’m just getting started… and still need to rip the majority of my music collection to build a digital music library first, before testing the various software.

There are plenty of free DSD files out there. www.2l.no has more than a handful (http://www.2l.no/hires/index.html). Some others require you to sign up for a newsletter to get them, but if you don’t want more email, you could then cancel the newsletter. (for example http://bluecoastrecords.com/free-downloads)

Sweet. Thanks Ted!

Success! Both the Stereo DFF - DSD 124 and DSD 64 sample files played correctly (from… http://www.2l.no/hires/index.html), when I dropped them into Decibel’s playlist window. Thanks again Ted!

Cool. I think you'll like them. BTW if you're on FPGA version 6115 you can also play the original DXD files (352.8k PCM) from that site. There shouldn't be a big difference but you may hear a little difference between DXD and DSD...
