From an Editor's Notebook: An Update on PFO's DSD DAC and DSD Download List
by Dr. David W. Robinson


Just in case you haven't been paying attention to DSD, there are revolutionary breakthroughs afoot for fine audio in this domain.

We've been documenting DSD's progress here at PFO (for example, Issue59/dsd.htm, Issue59/dsd2.htm, Issue60/dsd_usb.htm, Issue60/dsd.htm). I've also moderated DSD seminars with some great hardware and software experts in this format at RMAF 2011 (streaming video available at, THE Show Newport Beach 2012 (streaming video available at, and RMAF 2012 (video available in the near future).

To bring you up to date on what's happening, here is my current list of DAC manufacturers who are either already producing DACs with DSD support, or who have announced that they will be supporting DSD in the near future:

My industry sources tell me that there are definitely other hardware manufacturers who are already developing support for DSD in their DACs. While I'm tempted to share that information with you, I'll wait for definite releases of their hardware. We'll keep you updated here at PFO.

DSD download sites, 10/24/12

My current list of DSD download sites has the following URLs as of late October, 2012:

Channel Classics, the best model that I've seen for DSD downloading and a graduated price structure… smart!: for general access, and for their DSD catalog.

Morten Lindberg and company at 2L have a nice set of DSD downloads at Check their “Hires download: test bench” section, and scroll down for their sample DSD files. I am strongly encouraging 2L to expand their DSD download sections to include entire titles from their great SACD titles.

Cookie Marenco and friends at Blue Coast have some really good sample DSD files for sale…check out

Cybele Records, a German site; for DSD see that option at I think that we'll see more DSD downloads from Cybele in the near future.

Check the PS3 SACD site for more interesting links for things DSD: for a collection of DSD downloads

eOnkyo has been selling DSD online in Japan for a while. You can go to the raw Japanese page at, and then check the Google translation page to English at I'd like to see much more of this… in English!

Also in Japan is Same comments as for eOnkyo… let's have some language choices!

The group Wheatus is offering sales of their music in DSD direct to the public for a very reasonable donation of $5.00 (or more) for each of two EPs. Browse over to for the details.

David Elias has done some wonderful stuff on DSD; check out his album The Window, produced in tandem with Gus Skinas, at

Here's a general-purpose site where various artists and labels offer high resolution recordings for download, including DSD:
