RE: [SurroundSound] Re: Convert SACD ISO to individual DSD tracks?

Just to throw in some really gritty detail to this – about 3 years ago we looked at which DACs could natively decode DSD. There were about 3 and intended for low end decoders using differential single bit decoding.

Most DACs are ladder types and although accept a DSD input actually convert to PCM inside. I know there are some silly money types that will do the decode but most will only do PCM, so why the issue of doing the decode at source when error checking over PCM connections is now state of the art? Is DSD?

BTW I stick to analogue outputs as I don’t believe that DACs should live in the same box as power outputs, having once designed amplifiers.

Yes it will decode it into PCM.  If you don't mind the conversion it's a rather elegant way of getting around being able to play SACDs from a computer.  AFAIK still can't be done and gets converted to PCM.  I think a couple more DSD capable receivers have come on the market--I don't know if they would handle the DOP protocol.  So far the number of outboard DACs able to do this is still in the handful quantity though it's changing rapidly.  I think there was some interest in having the plug ins work with HDMI and AVRs but I believe there were some problems with different implementations that prevented this from happening.  Some RECENT AVRs came out with USB ports to act as DACs and those MAY be capable of playing them natively. If you are just concerned with playing the iso's without care for PCM/DSD they should play just fine on most equipment over HDMI--it'll just be some version of PCM.  Again if someone knows of some gear getting around this there is much interest in native DSD on AVR type equipment.  Even a DSD capable DAC doesn't mean that is what you will get--I can get music to my Oppo in a variety of manners but the only way for the DAC to recognize it as DSD without conversion is with a disc.

I have no problems playing .dff using Foobar2000.  A composite .dff file will split and play each individual "track" as a properly named and tagged DSD codec trrack with the ID info completely correct within Foobar2000.  You simply need to install the DSDIFF Decoder component (latest version is 1.4).  The tracks sound tremendous and I have no problem playing them whatsoever...  :)

Just to be clear I was speaking of playing dsf, dff, iso's through a software player on a computer.  NOT about DSD over HDMI in general.  Of course DSD travels over hdmi since v1.3.  I was only speaking to playing these files thru foobar or Jriver over hdmi to a receiver.  I hope that I wasn't being condescending about it.  I've been following these forums about SACD ripping for a while.   As recently as 2 weeks ago the software was unable to do DSD over anything but USB.  That isn't to say it's impossible to do so.  They just weren't writing the drivers for that.  Obviously if you burn the ISO to disc and you have a DSD capable receiver you are going to get DSD.  But I believe we are talking about plug ins for software players like Foobar and Jriver.  You should let the folks at CA and AudioCircle that you have figured out how to get the software to play native DSD over HDMI through these programs.  There is a lot of interest.  If you need links let me know.

• My apologies.  Last time I checked with the folks doing the plug ins they didn't support HDMI and there were no plans to do so.  If that has changed thanks for letting me know.  I do realize that ISO's on a disc will play over hdmi.  I was not aware of any solutions that let you play iso's from Foobar or what have you natively without a USB DAC (Im not talking about playing a disc on an oppo).  Again if that has changed great news.  Recently playing DFF, DSF, and/or Iso's thru a software player on a computer required a USB DAC and wouldnt output as DSD over hdmi--it was all converted to PCM.  Again if that has changed great news.

August there are some receivers that will take DSD over HDMI.
 I have a Pioneer 610 SACD/DVD-A player (clone of Oppo) it will output
5.1 as well as stereo DSD over HDMI only IF it is connected to the
right kind of receiver, such as the VSX-LX50 or the SC-LX90 (both
Pioneer). The player checks that thr connected component is DSD
capable before it will allow HDMI output of DSD, it the connected
component is not DSD capable then no sound is sent over HDMI.
BTW generally all the USB DAC solutions only have stereo DSD input.
Not sure about the Mytek 8x192 ( I think it called) it is Mch but
maybe not native DSD?
