What's 'native' dsd?

It's DSD, as on an SACD: 1-bit, sampled at 2.8 MHz, which is 64 times the sampling rate of redbook CD's. It hasn't been converted to a PCM, multi-bit sampled format. The .dsf/.dff files are container formats for native DSD. The Oppo DACs can read DSD and convert to analog output without any multi-bit, PCM encoding of the digital stream. If you choose to do any audio processing in the 105 (downmixing) or bass management, then the 105 will have to convert the native DSD stream to a multi-bit (24 bit, 88.2 KHz oversampled) PCM stream before converting to analog output.

Thanks, I'm familiar with DSD when it's been placed within it's more familiar .dsf and .dff containers. I've never seen it free from a container as an elementary .dsd stream - if this is what you mean

That's want I meant as opposed to a transcoding of the DSD stream to multi-bit PCM. There are other methods of streaming DSD also...DoP (DSD over a PCM container, transmitted via async usb), and DoPE (same as DoP, except via ethernet).

I am also a happy Synology user but playing music direct to an Oppo BDP-105 is not an option if, like me, you need gapless playback.

Gapless playback is mainly (though not exclusively) a requirement for classical music. To get gapless playback, I use BubbleUPnP to direct music playback to JRiver Music Center on my PC, which is connected to the asynch USB input on the back of the Oppo, The music files are served from my NAS using MinimServer.

Yes, you can. Natively too, without any conversions/transcoding. The Synology Media server can push .dsf/.dff formats to the Oppo player, no problem.

I don't think the Oppo players can decode native dsd from their hdmi inputs, correct?
Correct. The HDMI Inputs do not accept HDMI DSD.

So when you say that I worry anything coming down HDMI from the Acer is not correct.
That could happen for video due to color space or other issues, but audio is different. If you can bitstream the audio on the HDMI output, you will hear no difference between streaming from the NAS and using the HDMI output from the HTPC.

If you mean to take the HTPC out of the cabinet entirely or you are planning on streaming video, then you probably do want a DLNA server given what you have said about the video quality.

Yes, video is my primary use for the 105. Music, while important, is secondary. So did someone say which (jriver etc.) server software is best for handling a large video library (2000+ files) on a Synology? One of my real goals was to not have to boot the HTPC. The NAS will always be on, and the 105 boots relatively fast, so I'm exited to not have to fuss with booting the computer. Even though my revo has a really elegant keyboard mouse combo, it is still a PITA. Right now for music I have a silly setup where my notebook has the audio files (HTPC full to the brim with video) and I run Foobar on the HTPC which then feeds the music beast (with a kluge of having to switch from the Realtek sound card onboard, to the external streamer DAC). Foobar is great on all the Android devices for handling the playlists/album art/queing once it's running, but so many times I'm too lazy to boot the string of computers and programs it takes to make music play. That said I have had a great experience with Foobar for audio/streaming, but am pretty certain it isn't good for video, whereas I've heard jriver is good for everything??

The comment above about gapless did also bring up an important point I was going to ask later. Sorry, it really is my worst nightmare to still have the HTPC anywhere in the chain. Any way to keep it out of the equation for both video and audio? And the extension of that is if I buy the NAS I sure as heck don't want an external USB being my audio repository. At the moment I only have flac and mp3 audio. DSD hasn't reared it's head yet.....but maybe later .
