Confusing. There are jitter busting solutions (USB power filters) that can help improve things but the audiophile rule, going back to the analogue days, of keeping the signal path short and containing as few components as possible is probably best followed. Andy_Spinks (Andy Spinks) 6 January 2017 18:49 #1 Exciting news that MQA is available through on Tidal, and works through Roon! You will be told that WiFi doesn’t work well for Roon. I’ve gone for the latter method as I can optically isolate the noisy Raspberry Pi ground from the DAC. Where did you see them say that? Additionally, I have ordered a faster USB wifi adapter for my windows core server upstairs. MQA works to preserve timing information that is typically lost or “smeared” by conventional compression techniques and some digital filters. I’m confused, how is your Raspberry Pi actually decoding MQA? Having used my RPi3+Digi+ Pro for the last couple of years very successfully as (at various times) a Plex and Volumio client, I'm in the process of moving the entire house (various 'legacy' systems) to support high-quality (lossless, hi-res & MQA). The Dig HAT employs a WM8804GEDS S/PDIF interface chip and crystal oscillator to adapt the I2S audio stream from the Pi to the TOSLINk and Coaxial outputs. MQA on Raspberry Pi? Step 3Convert Tidal music for Raspberry Pi Now, you can click the "Convert" button at the bottom right corner on AudFree main interface. Powered by Discourse, best viewed with JavaScript enabled, Audio dropouts streaming Tidal MQA to raspberry pi with hifiberry digi+. MQA allows streaming services to increase quality and/or reduce bandwidth over the more typical MP3 files you may be aware of. I think at last count we have about 12 endpoints, all on wireless. Wired network connections would be difficult with my home’s layout. I have had limited success with onboard wifi with Rpi. It has worked wonderfully ever since. My middle name is Brearley, named after my grandfather whose grandmother was Scottish, so we were told. Thank you for your idea Graham. Disclaimer; I’m a non-techie Roon use who’s just bought a RPi to use as an endpoint, so about 2 pages ahead of you in the Roon manual! A Pi w/ RoonBridge will pass through undecoded MQA just fine, so the DF Red can perform its unfolding magic after the MQA firmware update. Anyone from Room care to help - I appreciate there may be commercial reasons you can’t say yet. The main reason for this is to be able to benefit from MQA encoded music. I’ve chosen a digital audio interface card with a dedicated, good quality clock for driving the S/PDIF interface over both optical (TOSLINK) and coaxial interfaces. When this happens the “Authentication” MQA studio 96kHz blanks out momentarily. Must read properly. There are several ways to experience MQA that are inexpensive. The Raspberry PI model 3 is an ultra-capable miniature sized computer that I still use to this day for my audio applications. The latter allows the DAC design to employ a local clock source (typically 17.2032 MHz) and to generate the precise clock rates to match those used during encoding. Low cost is obviously one of the primary advantages of RPi end points. There are further complications arising from USB supporting synchronous and asynchronous modes. Audiophile-quality music playback for the wonderful Raspberry Pi family of single board computers. Once we’ve downloaded our chosen OS, we must write it to a microSD card (using balenaEtcher or similar). I have read that the Pi USB is terrible for DAC connections, Your email address will not be published. Both the Red and Cobalt have an inbuilt headphone amplifier and there are immediate benefits even with non-MQA encoded material. In other news, AudioQuest announced that a firmware update will be available to enable MQA support on the DragonFly Red & Black. [Side note: the RPi hardware supports Ethernet and Wifi but some operating systems are Ethernet only.] Although it’s referenced in several other threads as well. I have attached an image of the signal path . MQA allows streaming services to increase quality and/or reduce bandwidth over the more typical MP3 files you may be aware of. Playing TIdal Master MQA through My M2Tech EVO Hiface to my NDAC results in the highres light going on. (Although that would be an excellent way to differentiate one’s product in the marketplace. For a few years now I’ve subscribed to Tidal HiFi quality streaming service. Core Machine (Operating system/System info/Roon build number), Windows 10 Desktop core intel core i3 (clarksdale) Roon 1.6 build 416, Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet), Core machine USB 2.0 AC 600 wireless adapter, Netgear 6400 AC1750 router, raspberrypi 3B internal B/G/N wireless. PC and MAC USB audio is fundamentally constrained by the electrical power supply noise and jitter of these computing environments. This topic was automatically closed 365 days after the last reply. My reading of things is that you’re correct; when the DF becomes MQA’d then an RPi should give you the full experience. Once finished, you could click the "Converted" button to locate and check the converted Tidal music files on your computer. USB combines clock and data so to receive bit perfect data in the DAC, some very accurate clock recovery system is needed. Still surprised, but DSD upsampling be a welcome addition for my DietPi endpoint. ), Powered by Discourse, best viewed with JavaScript enabled. I haven’t tried the Dragonfly on the Pi USB but I could see if it works. A DAC uses a data input feed (1s and 0s) and a clock (a way of telling the DAC when to load the 1 or 0 presented to it on its data pin). I ALWAYS add a USB wireless dongle (they are all "old"tech 2.4 G I believe) and am streaming hi res Flac and Qobuz & Tidal with no wifi issues, I have several RPi endpoints and all work well. You might also check if your running a “lite” version (I use DietPi) with NO GUI. None. By the way - great name! Raspberry Pi 3B running dietpi, roon bridge, 3.5 Amp 5v power, Hifiberry digi + toslink optical to Shitt Modi 2 Uber also tried USB to DAC. At the time of this publication (February 2019), I probably went through a dozen Linux distributions, using the PI as a source for my DAC. the Pi is just a streaming endpoint for Tidal using Volumio. For a few years now I’ve subscribed to Tidal HiFi quality streaming service. I’m guessing that MQA licensing is not free, so I wonder if there will ever be a HAT with MQA. A middle ground when using a streamer based on a low spec device like a Raspberry Pi is to use the Pi’s I2S to drive a DAC directly or if your view of the available DACs is a poor one, then drive an S/PDIF digital audio interface to a quality DAC and suffer the jitter issues associated with the S/PDIF interface. Typically this means buffering the streamed audio data received over the internet and very carefully transferring it to the DAC used to render the decoded and rendered MQA audio image. I’m new to the Raspberry Pi thing, but it sounds like Roon Bridge makes it pretty easy to get a USB DAC working on the Pi. **Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc. Whether this will have the same limitations that the Tidal app has, or perhaps something more elaborate for DACs Roon knows the exact hardware of (USB and RoonReady) remains to be seen. I was hoping you’d found a way to get the RPi to do the first unfold on the software side and then maybe a Dragonfly connected to the Rpi via USB to do the final unfold, rendering a full MQA file (since the dragonfly is only capable of doing the final unfold AKAIK). The black is the cheapest but due to the lack of headphone amplification I’d avoid this and start with the Red. If that means MQA capability? New replies are no longer allowed. However Roon does that already, so what is 1.3 going to bring over and above that. For example a PC with a TIDAL HiFi trial subscription will decode MQA files to a maximum of 24bit/48kHz, which is an improvement on the typically 16 bit compressed audio that you’d have previously experienced via standard TIDAL or Spotify services. I’m sure that can be true, but with good planning and a good mesh (I get better than 200mbps) it can work well. So if possible chose a streamer than can output I2S at the correct sample rate and feed this directly to the DAC chip. This card is the Just Boom Digi HAT. Thank you for any help. Oh and I think V1.3 will also bring upsampling up to DSD rates (should your DAC be capable of handling it). There are currently 3 DACs in the Audioquest Dragonfly range and they all decode MQA.

(Through Roon the second light on my NDAC does not lit). Whilst so called HiRes Audio is all about uncompressed music of maximum resolution and bit rate, MQA focusses on a combination of uncompressed and compressed audio which remains backwards compatible with legacy playback devices in the event they are not MQA enabled. Your email address will not be published. I bought an Audioquest Dragonfly Red for this purpose. Not a big issue for you as all you need is a firmware update, but great news for me as my M2Tech HiFace DAC isn’t due to get MQA capability. In other news, AudioQuest announced that a firmware update will be available to enable MQA support on the DragonFly Red & Black. It seems like the only way to stream MQA from a RPi is to connect a DAC that does both unfolds. If you don’t have any MQA content in your current library, you can download a few samples from the 2L Test Bench (<-clickable link). Follow. It appears Roon will offer software decoding over time. One thing you may have missed. I have a “WiPi” dongle from and older raspberry pi. Then the program will begin to convert Tidal audios for you in a faster speed. I am able to stream FLAC 24/192 stored on the core machine without any audio skipping. That’s going to avoid the issues of generating and re-constructing clocks. The good news from the measurements I’ve seen is that the Pi3 with Dig HAT streamer is a great choice and saving money here leaves more money for the more important DAC. See the thread in this forum entitled ‘Article on DAR about Roon 1.3’. Thanks for the pointer to the 1.3 article. Exciting news that MQA is available through on Tidal, and works through Roon! Now 24/192kHz and 24/384kHz take even more bandwidth and storage making them impractical to steam and expensive to store. While streaming Tidal MQA 192 to my raspberry pi / hifiberry digi+ bridge, I get regular audio dropouts. As usual, the only way to decide which is better is to see it you can hear the difference. I like roon but I want to get this figured out quickly before my trial period ends. I missed that over the holidays. I want to find a workable wireless solution. The ultimate is the Cobalt. Or that I may have got wrong - can other please comment (Renee?!). There are currently no MQA compatible HATs available that I know of. Step one is to add an MQA compliant USB DAC to your PC running TIDAL HiFi. I will try that solution this evening. If so then the cost of Roon is starting to look decidedly good value (not that it wasn’t already), Comments welcome from those who know what they’re talking about, not 100% sure I know what I’m talking about but… looks software decoding will only be capable of unfolding MQA files’ sample rate but you will still need MQA certified hardware to get the full MQA quality, Having read up a bit more since my post that would certainly seem to be the case with the next release of Audirvana coming out soon ( see MQA website).
