  1. Hi Jim, Given that you are proposing to use the Spotify desktop application to control the playback and not the audio file player software that you'll be passing Spotify's audio output to (so use the player just for upsampling), why don't you just use the foo_dsd_asio plugin for what it was designed for, ie, the foobar2000 player? Incidentally, how did you intend getting the Spotify'desktop app's audio output to JRiver Media Center in the first place? John
  2. Ignoring the bit about tying up the iPhone to use as a streamer (which I don't remember the OP asking for), how is this in terms of quality any different to getting to the Chromecast Audio to network stream and play the same files from the PC? Big hint: I'm also questioning your assertion that network streaming audio files via Google Cast is "mid-fi" like Bluetooth.
  3. Ok, thanks for clarifying also needing to set the Mode to "Original" to make sure JRiver does not transcode. Otherwise just using the default setting of the "Audiophile 24-bit DAC" DLNA server for the Mode, which is "Specified output format" (and given the default setting of Format is "PCM 24 bit"), would most certainly engage transcoding to 24-bit PCM! Possibly, but I've tested this since version 21 of JRiver and its UPnP/DLNA media server is certainly able to provide DSD files natively for streaming, if the Mode is "Original" and DoPE is off. Which reminds me, I've previously posted about this, with a fair amount of detail, about the appropriate settings for JRiver's UPnP/DLNA media server to make sure it doesn't transcode, in the Streaming and Teac NT-503 thread: https://www.computeraudiophile.com/forums/topic/28322-streaming-and-teac-nt-503/?tab=comments#comment-672888
  4. Hi wklie, Why are you suggesting setting up JRiver's UPnP media server to transcode? Namely: - Setting Tools / Options / Media Network / Add or Configure DLNA Server, add 24-bit Audiophile DAC -> this forces all PCM files (including lossless FLAC, ALAC, AIFF) at all resolutions to transcode to a 24-bit WAV file (at the original file's sampling rate - assuming you haven't engaged any other JRiver DSP); - Turning the Bitstream DSD (DoPE) -> forces all DSD files to be transcoded to DoP contained in a WAV file. In other words, given that the Lumin streamers can play lossless FLAC, ALAC, AIFF & indeed WAV PCM files and DFF & DSF DSD files natively from a UPnP/DLNA media server over the network, why are you suggesting that the JRiver UPnP/DLNA media server should transcode, especially for those PCM & DSD file formats, to 24-bit WAV and DoP as WAV, respectively? John
  5. Without knowing the provenance of the hi-res files when comparing with MQA, I'd personally be more inclined to remain skeptical. However, comparing the 2L sample downloads I mentioned, would certainly go a long way to removing those sorts of doubts.
  6. Lumin streaming devices work with JRiver just like any other standard UPnP/DLNA renderer - you have the option of: either using JRiver Media Center's built-in UPnP/DLNA control point to control the playback of the renderer streaming audio files from any UPnP/DLNA media server on the network; and/or using JMC's built-in UPnP/DLNA media server to provide it with audio files (from JMC's own media file library) to stream from over the network. JMC's UPnP/DLNA media server has been designed by JRiver to only provide the UPnP/DLNA renderer with descrete audio file tracks, not the (realtime) digital audio signal produced by JMC itself decoding & playing said audio files through its audio engine - if that's what you mean by JRiver's "output" to an "end point". However, JMC's UPnP/DLNA media server can be configured to apply some of its DSP functions to alter the original file tracks while streaming, ie, it can transcode the audio data contained in the file being streamed, even convert it to another audio file format. Incidentally, Lumin streamers support both standard UPnP/DLNA streaming and OpenHome (aka UPnP with Linn extensions) streaming. JRiver Media Center can only control standard UPnP/DLNA renderers, but can provide audio files over the network for both types of streamer.
  7. Hi Kelly, Perhaps you could give us your own opinion, though not using TIDAL as the source. This is because there's no way of telling whether TIDAL Masters MQA tracks have come from the same original source as any hi-res conventional PCM version of the same tracks you may already have. Certainly the suspicion, by some, is that the majority of the 16/44.1kHz CD resolution TIDAL HiFi tracks are not derived from the same source as the TIDAL Masters MQA tracks. However, using the free files available to download from 2L Label's test bench, you can confidently make a direct comparison, as all the available resolutions and encodings, including MQA, have been confirmed to have been derived from the same DXD source: 2L High Resolution Music .:. free TEST BENCH An interesting comparison would be fully decoded MQA vs all available hi-res & CD resolutions of the stereo 'normal' FLAC files (including DXD). Another one, perhaps, would be to compare undecoded MQA with CD resolution FLAC. John
  8. Yes, understood. The display needs to reflect the mode selected.
  9. Excellent, thanks for that wklie! Ok, so for local files, MQA off mode equates to MQA passthrough mode without the upsampling/volume control and analogue output restrictions.
  10. Hi wklie, Does the Lumin device support for Full Decode MQA apply to network streaming your own MQA files (ie, provided by a UPnP/DLNA media server on your own network), or is it just for the TIDAL Masters streamed from the TIDAL Hi-Fi online service? If it does also apply to streaming your own MQA files, what happens if you select the Off Mode for MQA when streaming your own MQA files? I'm assuming this is not possible when streaming your own MQA files, even if you have logged into TIDAL Hi-Fi: John
  11. Indeed, plus LMS even has a plugin for the Chromecast Audio itself!
  12. Agreed, though I hope you don't mind me clarifying "you need both" means requiring: any UPnP/DLNA media server (eg MinimServer, JRiver, etc), to provide the audio files over UPnP/DLNA and the BubbleUPnP Server to provide the bridge between UPnP/DLNA streaming and Google Cast streaming (ie the Chromecast Audio). The OP may not want to use a handheld device for a UPnP/DLNA controller, so can still use the laptop, eg, JRiver will work for this. The foobar2000 audio file player can be used as an alternative to JRiver and with the foo_out_upnp plugin, has the added benefit of allowing you to supply an already gapless audio stream to mitigate the Chromecast Audio's lack of gapless support.
  13. The OP appears well aware of JRiver itself being able to access the folder tree without any such problems: Is the issue one of being restricted to using an Android device to control JRiver (the BubbleUPnP controller app is only available on Android)? This would narrow down the options for 'pure'/non-UPnP JRiver remote controls, eg, the Android JRemote app (which unfortunately doesn't have the reputation of the iOS version) and of course the free Gizmo app.
  14. If @chrillewas referring to the live BBC Proms Binaural taster, located at: http://www.bbc.co.uk/taster/projects/proms-binaural-2017/try then the binaural stream appears to be in MPEG-DASH AAC (320kbps), rather than lossless MPEG-DASH FLAC: https://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/proms/client_manifest.mpd
  15. MinimServer's developer has decided to publish the instructions to use the prototype: " Owing to popular demand (four more PMs in the last few hours), I have decided to publish the instructions for using the prototype. Regarding the need for WAV transcoding, many players can play the FLAC stream without transcoding but a few players cannot. Even if transcoding isn't necessary, it might be desirable because of possible improvements to sound quality. In the instructions below, I have explained how to play the stream with and without WAV transcoding so that people can choose whether or not to enable it. To try the prototype test build, do the following: 1) In the Packages tab of the Properties window, type the following in the 'Other package' field: minimserver-0.8-update-102 2) Click Install and follow the prompts to install the package 3) When installation is complete, click Relaunch 4) Repeat the above for this package: minimstreamer- 5) Add the following lines to a .m3u radio playlist: #EXTINF:-1,[*R3DASH;flac] BBC Radio 3 lossless http://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/lossless/client_manifest.mpd 6) If WAV transcoding is required (or desired), set the stream.transcode property in the System tab of the Properties window to the following: flac:wav24 7) Rescan the library 8) You should now be able to play the lossless stream to your renderer Please report any problems by posting to this thread."
