I'm also looking into Audirvana as well but, again, just starting to look into it. But.I don't know, just diving in and I APPRECIATE your input. Does the MIDI setup default BACK if the speakers receive audio of a lower sample rate? I would think if you assigned settings to the output in MIDI setup they should remain. ![]() It's great that it automatically "senses" the sample rate of the audio. I have heard of BitPerfect and JUST started to look into it. I know, 48 kHZ is the standard in the video field – still, it sounds to me a silly decision to force upsampling. At least it'd act like an Airport Express. AppleTV should simply have an option to enable bitperfect playback. I like Apple in many ways: I wish they would be more audio friendly in this sense. The Airport Express is surely more "hi-fi" because, as you say, there's less processing (only downsampling to 44.1 kHZ due to Airplay's limit). Just another example of Apple complicating audio users' lives. I have to use an audio HDMI-TOSLINK de-embedder to hook it to my DAC. I own an AppleTV 4 which doesn't have the TOSLINK output. ![]() I know, 48 kHz is the standard in the video field – still, it sounds to me a silly decision to force upsampling. Managing your audio library natively with iTunes and enjoying hi-res audio at the same time. I, like many other "picky audio guys", understand what are you trying to accomplish. There are other hi-res-iTunes companion apps available, though. Developers are struggling to figure out a solution. It's related to the last versions of iTunes. Everything is done automatically and the Remote app let you remotely control the playback as you pointed out.īitPerfect unfortunately crashes from time to time. Using iTunes with an app like BitPerfect you even don't have to switch manually the sample rate in Audio MIDI Setup in order to match the sample rate of the songs. I've a Mac mini connected to a DAC through USB. The wired MacPro/mini way is even more "audiophile" (actually it's perfect from an audio point of view). The Airport Express is surely more "hi-fi" because, as you say, there's less processing (only downsampling to 44.1 kHz due to Airplay's limit). That should pass through the hi-res audio signal its just that I will have to control that machine via screen sharing or the Remote app.just not as smooth a "workflow".īUT.☺️.I may be replacing that Mac Pro with a new Mini in which case I'd get a USB-C to USB-B adaptor and plug into the KEFs that way with a similar "workflow" to the Mac Pro route. ![]() That was my ideal scenario.īUT.now I am thinking about using my old Mac Pro (2008) and going out through the Digital out on that machine directly into the digital input on the KEFs. Wanted to go this route so that I could easily toggle to those speakers in iTunes on my work machine. The plan is hook the AX into my network via Ethernet and then the 3.5mm Mini TOSLINK to the KEFs. Now I am thinking to use one of the GEN2 Airport Express' I have as well since the signal won't be processed twice. I have one Gen2 ATV and two Gen3 ATVs just laying around that I thought I might use because of the TOSLINK output. I don't know if this model works in the same way.Ĭlick to expand.Thanks for your reply, yeah I have been doing a bunch of research trying to figure this out. It works: not wireless of course and a little cable-messy. In my case I have to put a powered USB hub between the iPad and the DAC to make it work otherwise I get a power related alert. The tracks played from a locally shared iTunes library are sent in the native resolution. If your DAC/Speakers accept USB digital audio and if you have an iPad/iPhone you can connect it via a lightning-USB adapter. The purists/audiophiles are still annoyed by this down-upsampling nonsense, though. I'm still looking for confirmation.ĪppleTV unfortunately upsample everything to 48 kHz.įor example, if you play a 192 kHz track this is what happens -> Airplay downsamples it to 44.1 kHz and send it to AppleTV -> AppleTV upsamples it to 48kHz. For the 2nd version I haven't found any official technical specs. Airplay (the first version) is limited to 44.1 kHz.
