    Hi Andrej

    Our one time conversion of DSD is not dis-similar to the vast majority of DSD Playback over DoP. The difference is we perform the conversion one time rather than every time you play the music. our conversion is to the nearest accurate conversion rate so if you are receiving 24/88.2 then your content is in that range. Most DSD files are 24/48, 24/88.2 or 24/96. 24/192 is needless up sampling and technically distorting the sound.

    Other FLAC files in that folder should appear. Please select Settings, Music Library, Reindex Collection. Once the index completes, check your library for the missing music.

    If the problems persist, please select Help, Send Support Request so we may view your player log file and help you troubleshoot further.

    Tony, I know this is an old post but I couldn't resist commenting on your response.

    dsd over DOP is just encapsilating the dsd stream into a pcm container, it only works with dacs that recognize the flag and usually just over USB style DACS, there is no conversion with this method DoP is more akin to a DTS CD.

    Now that being said, I would prefer not to transcode my DSD files into any other format, but 24 88.2  is all anybody needs for a reasonable conversion, most people can not tell the difference. 

    The dsd approach is to do a very low bit rate and a very high sample rate, 1Bit/ 2.8Mhz .

    The benifits or lack there of, of keeping DSD in its original form varies from dac to dac and what kind of bass managment and auto speaker correction might be on your reciever/DAC.

    Just my two cents hopefully it worth at least that.

    I have a Bluesound Node. My master storage is a 4TB HDD and more than half of my library recordings are DSD or High-res. When I play-back my tunes without an exception all are played back as Flac 16 bit 44.1 khz. It is disheartening to see a reduced performance of my system when I run my newly purchased Node in my system. Yamaha's MusicCast which can play up to and including 192khz/32 bit recordings combined with my CX-A5100 Pre-Pro without altering the format of the original source. I can hear a significant increase of sound quality when I play back in its native DSD format.The reason I opted for the  Node was 256GB maximum storage limitation of the CX-A5100. Mind you the Node does a good job of indexing the files in a reasonable time frame. Is there a way to avoid this automatic format conversion of the Node, if not, any plans to update the software to allow users to keep the source formats un-altered?

    Hi Ned,

    DSD won’t as far as I am aware be natively supported format on Bluesound hardware, their sister company NAD do however have products that support DSD but their devices target a different user which may be you.

    Running two libraries (like I do can be painful) I have a master library with tracks in their original format / bitrate, converting them to FLAC 24/192 and storing them in a working directory on my NAS for use with Bluesound devices.

    On the fly conversion using the Bluesound hardware would require a significant amount of CPU time and local memory, add to this the network bandwidth required for multiroom playback and you can understand the technical constraint’s especially as some Bluesound hardware was launched in 2013 and would have been designed a few years prior when memory and CPUs were much more costly than today and still runs the current firmware.

    Perhaps using Roon would appeal to you and your large DSD library? tracks are unaltered and converted on the fly using the hardware server dedicated to Roon. This then sends audio out to Roon endpoints such as BluOS enabled hardware.
