    HQ Player

    Upgraded to 4.3.0 on my Mac Pro. So far, no worries. I also upgraded NAA to 4.0 and that is working well too. I appreciate the extra information the new version provides. @Miska, one question for you. I have two Oppo DACs, a UDP-205 and a portable HA-2. Since the HA-2 is getting older and the battery is worn, I use it now exclusively as a stand alone DAC that doesn't travel with me anymore. The original specifications of both Oppo DACs were that they could do DSD256 in "native" mode. The 205 broadcasts this ability correctly and both Roon and HQPlayer/NAA see this and respond accordingly. But the HA-2 doesn't somehow and so both Roon and HQPlayer/NAA only allow DoP to this device, limiting DSD to 128. I have tried DSD256 with JRiver on the HA-2 with success since you can literally force it to do so. Is there any way to modify HQPlayer to handle this specific DAC feature?
  2. I wouldn’t think so. The whole point of the NAA software is to make HQPlayer available to a device that isn’t close to the DAC physically. If the DAC is directly connected to the HQPlayer machine, then NAA is superfluous.
  3. Never mind. I figured out what I was doing wrong. DSD256 works on the HA-2 via the NAA.
  4. I'm going to try to do this for you. I have two Oppo DACs....the Oppo 205 and the HA-2 portable model. The 205 seems to work across all DSD modes with the NAA just fine. But the HA-2 doesn't seem to recognize it's capability to do DSD256 via native mode. I've tried everything and the best it can do is DSD128.
  5. Very interesting turn of events... I for one am very happy that Amazon has decided to go this route since it will likely push the bigger services (Spotify and Apple) to follow suit. It's an open secret that Spotify has been testing this for some time. Apple has been asking for hi-res recordings from content providers for some time but as it stands, has only been offering 256 kbit "Mastered for Apple Music" recordings. Yes, the advent of cheaper, wider bandwidth is a motivating factor but disk space in data centers is a lot cheaper too and frankly is a fraction of the space of all the video content out there. But I think the real motivation is the fact that HiRes music likely has a higher profit margin than regular compressed music given the increased cost to the user versus streaming/storage. And the streaming services and content providers would love to have higher margins any day of the week. Of course, audiophiles are a fickle bunch, often difficult to attract as a permanent customer. Amazon launched HD music today with a lot of partners but not any "front ends" like Roon or Audirvana, at least not yet. Still, competition is good. I subscribe to both Apple Music and Tidal so I'l curious to see what Apple and Spotify do in response.
  6. Surprised there hasn't been more chatter about this. There is obviously still a lot we don't know about this service but it's significant since it's the first CD and HiRes audio from one of the big three streaming services. There are a fair number of logos of companies involved in the launch including Denon/Marantz, Onkyo/Pioneer, McIntosh, Sony and many others. Curiously absent is Roon, where many of us use as a front end for existing streaming either from Tidal or Qobuz. I'm sure someone out there will take the plunge for the 90 day free trial to see how it compares. HiRes audio (Amazon is calling it Ultra HD) is supposed to be up to 24bit/192 khz depending on the content and Amazon discusses using external DACs for proper listening on devices that don't have streaming built in (like Heos enabled receivers/processors from Denon/Marantz). Like Qobuz, it looks like Amazon isn't relying on MQA for HiRes content.

    HQ Player

    Did you click the network access button on the HQPlayer interface?
  8. I've since moved onto Roon but I'm curious to try this anyway. As for AppleScript, there is probably a lot more of it out there in legacy applications than most people realize, which is why Apple is bothering keeping compatibility with newer programming models. There's been no indication or notice that it's being retired....it's just a mature technology that still has a purpose for some. And AppleScript is pretty mature, with the tech dating back to the HyperCard days.

    HQ Player

    4.0.3 seems to operate better for me, especially in DSD playback from PCM sources. Previously it would not work sometimes or default back to PCM. Now everything seems to work fine. One mystery...when i first ran 4.0.3, it locked up on the splash screen. A reinstall seems to have fixed the problem. Not sure what happened (MacOS High Sierra).

    HQ Player

    The one problem I can see with my solution with feeding an Airport Express into an input for HQPlayer via S/PDIF is what happens when i finally retire this aging 2008 Mac Pro. I don't think any modern Mac has digital audio inputs anymore. In theory you could have a input come through a Thunderbolt attached interface but i don't see any solutions among the docks that most popular right now. As it stands, this 8 core Mac Pro only has the horsepower for PCM upsampling and 16/44.1 khz PCM->DSD conversion. Any high definition music chokes on DSD conversion....there just isn't enough bandwidth in this machine.

    I've been experimenting with 4.02 (haven't upgraded for good yet) and I decided to do an experiment to get HQPlayer to play Apple Music. Yes, I know, not exactly CD quality but we subscribe to it and Tidal and there are times where you need to listen to something not in Tidal. In order to do this, I decided for the hardware approach and hooked up a spare Apple Airport Express to the Toslink input on the Mac Pro that is my current HQPlayer machine. It took me a while to figure out exactly how to make this work. Jussi's documentation isn't exactly detailed with many examples of the new Input URI format. And since I mainly use HQPlayer through Roon, I haven't been playing with the UI much at all. But I did get it to work! So here were the steps: Hardware: 2008 Mac Pro hacked to run High Sierra 10.13.6 HQPlayer 4.02 Apple Airport Express 2nd gen 1. Open System Preferences -> Sound 2. Make sure the Input default is the Digital In input. Play music through the Airport and verify that the little digital VU meter is seeing music. 3. Launch HQPlayer 4 4. Check the Input setting in preferences, choosing whatever output filter of your choosing and other parameters 5. Click on the URI pulldown and select "audio:default/44100/2. The list window then shows a single line item for the "input" 6. Double-click the "input" in the list window. At this point, HQPlayer should be playing whatever is playing through the input, or in my case, being provided by the external Airport Express

    New mac mini

    Maybe, but Apple tends to not change hardware configurations with MacOS that often anymore. Given that the 2018 Mac Mini isn't even a year old yet, we might not see a substantive upgrade before 2022, or whenever Macs go to ARM chips, whichever comes first.

    HQ Player

    It may seem steep and not all of us are completely price elastic in our purchasing decisions. That being said, this is a hobby that most of us have put several thousand dollars into over the years. The user base for HQPlayer is pretty specific, even amongst audiophiles and Roon users. Speaking of Roon, they solved the varying income stream problem by doing what many software vendors have gone to in recent years, a subscription model. It smooths out the income issues and lessens user angst that a user who invested in HQPlayer a year ago is being charged in the upgrade more than the one who got in five years ago. Maybe we'll see that at some point but managing that isn't as easy either, since Miska has direct sales and resellers.

    I'm successfully playing 4.01 on my existing system meant for 3.25 (at least the trial version....haven't upgraded yet). In my case it's an elderly 8 core 2008 Mac Pro 3.0 Ghz, 16 GB of RAM hacked to run High Sierra. I could move it to Mojave but there would be some problems with existing software I support on this system. Not using CUDA....Nvidia graphics card is too old. I have two different NAAs on my network, both talking to Oppo DACs (a HA-2 portable and a UDP-205). The NAAs are both running Windows 10. Both play correctly. Lastly, everything uses Roon in my house and that works too. The Roon server and HQPlayer run on the same old Mac Pro. At some point I will retire the Mac Pro for a faster machine but right now, this is what I have.

    HQ Player

    The iMac Pro and the Mac Mini both have the T2 chip. But the recently refreshed iMac did not get it. Speculation was that the T2 required a more thorough refresh which Apple didn't want to do right now for some reason. I imagine this will be the last iMac that won't have it.

    New mac mini

    OK true. I did read about the solution online but I guess you can't trust that pesky Internet sometimes. 😁 Oh well. In any case, my needs aren't centered around running my favorite Linux distro on a Mac. If I got a new Mac Mini, it would be running MacOS. But again, if a Mac Mini Core i7 machine could tackle most HQPlayer duties, then i'd be fine. All I'd need is 512MB for a boot volume or maybe 1TB for a stretch purchase since everything else this machine does would be on the USB 3 and Thunderbolt attached external storage.

    First, you can disable the T2's security measures with a supplied Apple utility so you can boot to Linux if you want. However, it's not on the main boot volume. You'll need to boot from the recovery partition to access it ("Startup Security Utility"). Reboot with the option key pressed to access the recovery partition. My Roon/HQPlayer machine as I mentioned is a 2008 Mac Pro. It was pretty stout 10 years ago or even five years ago but a modern Mac Mini will run rings around it. But the Mac Pro has much better thermals....so your methods of dealing with it are of great interest to me. My Mac Pro sits under the house in a non-living space so I don't care about running the fan at high speed all day since no one would hear it, especially over the din of my Dell Poweredge server :). (It's also ancient). As you may have guessed, I'm fully steeped in the Mac/iOS universe so while I can certainly build/operate a NUC Linux machine, I'd rather just go with a Mac Mini since I want to run Plex and a few other things the Mac Pro is doing now. And I don't care about a Mac Mini directly accessing a DAC since the DAC it would talk to (my Oppo 205) has a NAA if its own....in this case an elderly 2008 iMac running Windows 10. It's too slow for regular general use but it makes a perfectly serviceable NAA and/or Roon client. As it stands, nothing in my house is powerful enough to run the Oppo at DSD512 but it sounds like the Mac Mini can except for non -2 filters, which are currently not runable on most people's rigs.

    What filters can't your Mac Mini handle? I'm looking at a Mac Mini to replace my 2008 Mac Pro as a central server & HQPlayer machine.

    Ios and MQA

    Make sure your Mac is setup for greater than 44.1khz. You'll need to open the Audio Midi app located in Applications->Utilities. When you select the DAC as far as your output choices, make sure that it is setup for 24/96 as opposed to 44.1 which is the default. Your Mac won't pass audio over 44.1 over USB or HDMI unless you do this step first. Looking at the FAQ on DragonFly's webpage, it seems that it is depending on the source to downrez the audio file for best performance if the file is over 96khz. I guess the Red can do it's own downsampling but it seems it really wants the source to do it if possible.

    Ios and MQA

    Most MQA files on Tidal seems to be 96khz unfolded, but not all of them. Some are 24/192 (like Miles Davis Quintet) or even 24/44.1 (Jose James' Lean on Me album). I'd be curious as to what your DAC says about those recordings. 88.2khz is a more rare format (the same as 172.8).

    Ios and MQA

    I'm playing an MQA album though the Tidal app right now on my iPhone X + Oppo HA-2 portable DAC. It sound nice but outside of seeing "MASTER" displayed during playback, it's unclear exactly what it getting to the DAC. Roon at least gives you the detail of what the DAC is receiving. I'm assuming I'm getting either a 88.1 or 96 Mhz unfold depending on the track but it would be nice to get some actual feedback.
  22. In theory. I don't subscribe to Qobuz so I can't say for sure and I don't think Tidal has any multichannel files. But it does work for local 5.1 music in my library, all of which came from SACD of DVD-A rips. Receivers are an often available DAC for multichannel music since they are designed to do multichannel out of the box. It's not going to sound as nice as an Exasound 38, but if you have a computer running Roon client or Core next to your receiver, it's a easy way to do multichannel music. If you have an Oppo 205, it's HDMI input would work too and process it through a better DAC than most receivers.
  23. Roon can use HDMI output to a receiver or other comparable input to send multichannel music. I do this with an old Mac Mini running Roon client in my sun room off the kitchen. The Mac Mini feeds HDMI to a Denon X2000 receiver (about five years old). The Denon cannot do DSD but it handles multichannel PCM very nicely to the 5.1 speakers in the room.

    I’m an old Unix head but I can’t say I’m the best at Linux distros. But if there isn’t a pre-done text based installer, then instead of doing an install on an SSD, I’d prototype it first in a virtual machine like Oracle’s Virtualbox. You can tinker with it as much as you want and then when you get it right, you can do a final installation in Virtualbox straight to a mounted flash drive.
