  1. Has someone compared SQ of direct USB output from MBP/Audirvana to DAC vs. streaming to a device like Ultrarendu or USBridge with the same DAC and same USB cable ? Thanks Matt
  2. okay I have had an annoying problem using A+ to control an mr. my office system has remote drive-i-mac-audirvana-eitr-modi. My main system has ethernet-microrendu-usb-Gumby, controlled by a+ on the iMac. basically, I have occasions with no sound in the main system even though the microrendu is selected in A+. I confirmed that my computer is seeing the microrendu and the microrendu is seeing the Gumby. After much frustration, I was able to fix things by physically removing the connection between the iMac and the eitr and restarting. For the moment everything is working and I am able to toggle between systems by changing the output selection in A+. But it feels like there is an intermittent compatibility issue between A+ and eitr, where A+ at times will try to send a signal to the eitr, even though I’ve chosen mr as output. any other explanations?

  4. Hello, members of Computer Audiophile Forum! I’m the founder of International Classical Music Database, a non-profit organization exists to promote, educate, and archive classical music (don’t panic, the discussed topic is not limited to classical music). We are looking for some pilot users for a new online service. If you’re a music collector or audiophile with a Mac computer, I believe our new solution “Tonal” could bring you a better music experience: With Tonal, your complete digital collection is organized in one place and is ready to be streamed anytime, anywhere. That may sound unfancy, but there’re three foundational innovations which clearly differentiate the Tonal experience from the competition: A managed cloud-based music locker service with audio quality verification built-in. An innovative metadata solution which focuses on standard, quality, and community collaboration. A well-crafted playback engine which ensures highly predictable audiophile performance. Download initial version: http://binaries.ton.al/app/Tonal-20180315.zip Anyone interested please read the introduction article: https://medium.com/tonal-app/introducing-tonal-74c748f200b9 And three separate articles explaining its internals: Audio Pre-Processing Music Metadata Playback Engine This thread will be monitored. Feel free to ask me any question. Screenshots attached:

    High Sierra with Audirvana Plus

    Hello, I installed the Dev Beta 2 of High Sierra today on a new partition... yes i have a backup I wanted to see if it was better for A+ with the new Finder coding and see if some bugs would disapear for me like the stoping of A+ playing for no reason for 1 or 2 seconds once a week. For me, A+ have still troubles like others before High Sierra with the System Optimizer installing at first... in fact, i had to put back my preferemces of Sierra to make it works again Direct Mode is out also as it is dead since Sierra. I didn't try to replace de .ktext again to make it work because SuperDuper couldn't see my hard disk formatted for High Sierra new scheme thing. Onyx doesn't work either at this stage to repair the permissions after... So i enjoy A+ 3.0.7 like it is now, HQPlayer 3 still works and JRiver 22 also. I putted back my A+ music database folder where it is supposed to be and my preferences for A+ software, and all was back like before with playlists included The best thing for me with High Sierra, is now i can use the keyboard like it was before Sierra... Making the folder you clicked disappear while holding the ALT key to just keep the next one you have selected... and so on, to just have only one folder at a time open in the finder while browsing my music hard disc. SO GLAD that it is back for me!! The Remote of A+ still works with my iPhone like before and my IOS application 'Remote Mouse' on the Mac and iPhone still control my MacMini on the TV with the iPhone if i want. Parallels Desktop is still working with windows 10 installed on Mac Mini... nothing to do with music but needed by me That's it for now. Enjoying music on High Sierra
  6. My main music library is mostly FLAC, but I like to have AAC copies in iTunes. I found an automatic and free utility to do this, which although not updated in a long time, works fine with High Sierra and iTunes 12. https://github.com/cbguder/FLAC2iTunes
  7. I am struggling with the exclusivity option for the audio device in the Tidal app. I like it when a music app can claim exclusivity of the audio device on my MAC. I use Tidal app on MAC with MacOS High Sierra and OPPO USB DAC. In the case of JRiver, the JRiver app claims exclusivity when playing something and if one stops the music, the exclusivity is given up and other apps can use the audio device / DAC (Youtube, Chrome, Spotify, etc.). In the case of the TIDAL App on MAC, the app gives up the exclusivity automatically when another app/browser uses the audio device when launching the app and the settings in Tidal is set back to not exclusive. I have to check this setting all the time, as this happens often. Moreover, if Tidal has exclusivity it only gives the exclusivity up with closing the app and not when stopping playing the music. That is annoying. Any help to have a "JRiver" like experience with Tidal in the field of exclusivity?
  8. I have been using Audirvana+ Player (Mac OS) connected to my KEF X300A (Active Speakers) for years, playing mostly AIFF and WAV files. Recently the KEF speakers are no longer working, and I plan to replace them with my Cambridge Audio speakers. Since the new speakers are not active speakers, I will need an Amplifier for it and I am looking at Cambridge Audio CXA80. The question is, it seems to be that CXA80 has USB audio input and a WM8740 DAC chip, I believe I can connect it to speakers directly. Using Audirvana as player, do I still need to buy a DAC, or a network player, like DacMagic or CXN? What's the purpose for a network player (e.g. CXN) in my setup?
  9. Wondering if anyone is connecting MacBook Air as a one computer config so one usb port is connecting to dac, and internal ssd as boot drive - whats the best sq solution in your experience: 1. Use another usb port for external hdd - ssd, or just a regular drive? I play mostly dsd; 2. Use the SD card slot and better sq or not? 3. Use thunderbolt external hdd, better sq? Audirvana manual recommends making sure the high speed usb port are dedicated to usb connection to dac, not sure if the 2 usb ports on macbook air is on same circuit thus shared, therefore am wondering if using the other connection options may imprive sq. Anyone can chime in on this? Thanks.
  10. Just incase you missed it, Apple has added FLAC playback in High Sierra and iOS 11. This will make previewing music libraries much easier. Hopefully FLAC compatibility will be coming to iTunes soon too.
  11. Hi all Im looking for a cheap (sub £100) but good DAC that’s... - Mac compatible - Capable of playing back DSD 128 5,6Mhz .dff and .dsf files - Will also allow me to get the best out of my first pair of open back headphones (Beyerdynamic DT990 Pro 250 ohms) Thanks
  12. Hi all, I haven't posted since this forum moved so hello again! I'm hosting a barbecue on Saturday that is likely to go on well into the night, so I have compiled a playlist of approximately 10 hours of music. I want to make sure that if I need to stop the playback and start it again, I don't want to hear the same tracks already played recently. In conclusion, I'd like to create a Smart Playlist that will only show songs that haven't been played in the last 6 hours. Unfortunately, the "Last Played not in the last" shortest option is 1 day. I considered the "Limit to XX items selected by least recently played" option, however that will mean the music will be skewed towards music I haven't listened to for the longest, which is not what I want, because that ends up grouping lots of a similar artist together and it won't feel very random. I tried entering a fraction for number of days, but it doesn't allow that. Does anyone have any ideas on how I could get this to work? Thanks!
  13. After doing forum research, I decided it was possible to stream Roon from my Mac to the Roon-Tested 280D. Now I'm looking for you experts to confirm/deny before I install the over $1600 of gear purchased to make this happen! Set-up - my Mac, now with Roon downloaded, is quite some distance from the Moon 280D and the listening room where its housed. So it is impractical or impossible to directly connect a USB cable from it to the 280D. Plan - I purchased the ultraRendu microcomputer to work as a go-between. It will be directly connected to my router. As I understand things, it would recognize Roon and pass it thru via USB to the Roon-tested Moon. Concern - Simaudio is only pushing a direct computer connection, which is what they evaluated in order to become Roon Tested. I'm sure Simaudio has not tested the ultraRendu or all the many other similar products to determine their usability with Roon Hope - In spite of that, I'm hoping the envisioned solution is a workaround that's been tried and tested by others, whether the ultra/microRendu was used as the Roon end point or not. Thank you in advance for you help.
  14. There are several shell-scripts floating around (including one I made many years ago) that turn off a vast number of lanchd processes for OS X, which often have the perhaps undesirable effect of completely hosing the system. As an alternative, I have been watching /var/log/system.log to find clues about what might be problematic, and what I want to do is selectively target a few "processes" by understanding what they do, and then turn them off individually, to see if there is any difference (audible, or at least in terms of spamming the log file). I'd like this thread to become a "hit list" of processes that are unambiguously useless. (In other words, I don't want to turn off wireless or bluetooth -- this should be up to the individual user, and is easy enough to do anyway). What I want to do is target a few problem children that are unlikely to have any utility, especially if they are broken, and understand what they do, in case I change my mind (or discover an unintended consequence).
  15. I've used the iTunes artwork screensaver on my Macs of years and I think it's great, except I've had the same couple of dozen album covers for a looooong time now. How can I have it fetch more? I assume it caches a certain amount of jpegs, but I don't see a way to refresh. Maybe there's a cache file somewhere, or a folder that I don't know about. Any ideas?

    Ripping Audio DVDs on a Mac?

    Please can anyone suggest an application or method which can rip an audio dvd which just contains UNIX executable files ending in .AOB and .VOB. Nothing I have seems willing to look at them. I would have thought I should be able to unpack them to get the important bits out but, so far, no joy. The tracks are 24/192 HDAD two channel. I want to get 24/192 AIFF files. Cheers. Drew
  17. I just purchased the hiface1 interface which I have plugged into the back of a mac mini with SL. I've downloaded the software and set my sound output to be the HiFace. I am running it to a Bryston BDA-1 DAC. Software is iTunes with BitPerfect. Is there any other settings I need to set as I am not getting a signal to my DAC? Any help would be appreciated.

    Audirvana Plus1.3.5 config

    I open another Post, cos I'm no asking for the integer mode with Itunes. I'm a user of Audirvana Plus 1.3.5. and I'd like to know if my config is Ok. I think I have the 32 bits version ? Is it change something ? Is it the last one ? Mainly, in audio filters, appear sample rate converter : IZOTOPE 64 BIT- SRC ( for default ) an another option : apple CORE ADUIO. What's best ?

  19. Hi folks, Like many of you, I keep switching from one music player application to another, in pursuit of the best sound/experience combination. Lately I've come back to the JRMC+JRemote combination, which (at this point in time, for me) seems to be the best one currently. Yes, HQPlayer possibly sounds the best, and maybe I haven't spent enough time fiddling with it, but its spartan user interface (and complex options) makes it too difficult to use (again, for me), and even more so over an iPad Parallels Access remote connection (I especially hate that the iPad keyboard comes up every time I do anything simple, like change tracks) even for simple use, let alone playlist setups. I love the Audirvana sound and its native Mac interface, but (and maybe I'm doing it wrong) I've never been able to figure out how to reliably set up playlists that survive library changes, and even at its best, trying to control Audirvana via the iPad (even with the great Parallels Access automatic full-screen function) is way too fiddly. And the Amarra interface is so ugly (reminds me of a 90's era WinAmp skin) I just can't bear to use it (yup perhaps I care too much about the aesthetics...). So, until Audirvana gets its iPad remote app (hopefully soon...), I'm (at least this week!) back to JRMC+JRemote. JRemote really is fantastic - I've tried the Linn Kinsky and other remote apps, but only JRemote feels like a non-beta, mature app. Also, the latest version of JRMC now has a great "Pono" (heh!) skin which gives it close to a true Mac native Yosemite app appearance (thank god!). So, so far, so good. Decent SQ from the Mac player. Decent iPad remote experience. However, the one viper in this acoustic Garden of Paradise that crops up again and again, is the tendency of JRMC to crash. Repeatedly. Whenever I try to change tracks too quickly. Essentially, if I start playing a track, and then, within 2-3 seconds I try playing another track, JRMC crashes to the desktop, with the usual OS X Crash Report window showing up. If not the first time, then the 2nd or 3rd time I do the rapid track change thingy. Yes, 100% reproducible. So, why not just avoid this silly behaviour, you say... Well, unfortunately for me my missus and house guests do sometimes use the system too, and it's not practicable to conduct pre-use training for everyone! Enter Lingon, by a (I think) Swedish developer called Peter Borg. https://www.peterborgapps.com/lingon/ With Lingon X 2.0 (there is also a crippled version, Lingon 3.0 on the Mac App Store, which I haven't tried due to bad reviews) I've been able to (extremely easily and quickly) get JRMC to automatically restart every time it crashes. JRemote is also pretty good in that it pretty much automatically re-establishes a connection with JRMC whenever this happens (although one sometimes needs to hit the refresh icon to fix some playlist errors). Kudos, to this Peter Borg fellow, for Lingon, and for keeping it really cheap ($5 to $10). However, the frequent JRMC crashes really bug me, notwithstanding the above band-aid fix. Is this "crash on rapid track changes" problem unique to my system, or does anyone else experience it? If so, I was curious if anybody had a suggestion as to how I can fix it? Many thanks in advance!

  20. Hi I just unboxed an Airport Express (small one that looks like AppleTV) about 2 hours ago. My AudioLab 8200CD reports "No Lock" intermittently about once a second. My previous express (previous model) never had this problem but it died. I tried firmware 7.6.3 and 7.6.4 and performance remains the same. I have tried streaming from iTunes on a MacBook Air 13, an iMac 27 and a Mac Mini; they all exhibit the same issue. The Macbook Air and Airport Express are in line of site to each other and within 6 meters of each other. Is there any solution? ***PS, My Apple TV 2 works absolutely fine - I just swap it out for the airport express but I wanted to use the express for 44.1KHz. Thanks in advance.
  21. Hi all, I am writing this post to suggest that Sonic Studio includes in the next release of Amarra a companion App for iOS devices to provide full control of Amarra in a headless mac. I love the sound of current version of Amarra (Symphony) 2.5 I use a headless Mac Pro (tower) exclusively for Audio, and have trimmed down the OS (Mountain Lion) and disabled features as much as I could following many advices from other users. I only use Amarra in cache mode and playlist mode (without iTunes) an I quit the finder. Surprisingly, every single step improves the sound even though the computer is running almost at iddle (from Terminal "top" command). The remaining piece to get rid of is Screen Sharing. I use and iPad to control the headless mac with VNC software iTap. It works perfectly from the user point of view. But if I disable Screen Sharing, the already excellent sound gets even better. The processor does not have to take care of updating the screen and sending over the network to the iPad. However in order to use Amarra in the current setup, I need to have access to the Mac screen (with Screen Sharing). Spotify has two remote solutions (Spot Remote and Remoteless) that use a small server application in the Mac which is much lighter at using CPU resources, and the sound - without Screen Sharing and with the small server app - is better than with Screen Sharing enabled operating directly Spotify on the iPad clone of the Mac Screen. I also own Audirvana+ and even though I personally prefer Amarra Symphony, a remote App for Audirvana+ would be a welcome addition too. My expectation is that getting rid of Screen Sharing through the use of a custom remote App for Amarra or Audirvana+ may bring further improvements in sound quality than another iteration of the already fine sounding engines. Sorry if I became too technical or not too clear but for those avandced users I recommend experimenting at improving the Mac sound if it is used only for computer audio. It costs no money and you are rewarded with better sound. Regards, Jotauve.
  22. Sometimes, exactly very often, I lose airpaly signal in my ipad, iphone..imac...to send the music to apple tv 2. It does not appear the icon. And later maybe appears. I can not understant what's going on. I don't think is a problem with the wifi, because I can get music from my HD connected to the router. Has anybody else the same problem? Any help? My apple tv is jailbroken with black atv2. And I try it with itunes, spotify, another players.... Thank you.

    Mac Tagging & Album Art Download

    Hi all, I have an extensive collection of FLAC's ripped and tagged by XLD on a Macbook Pro which may be storing the album art within the FLAC (according to the settings). Musicbrainz Picard is used to retag some albums that XLD seems to have got wrong or to change some details to make more sense (i.e. 'DJ Tiesto' also appears under 'Tiesto' which needs correcting). Playback is via VLC on my MBP or via XBMC on a MacMini or old PC running XBMCLive. iTunes is not used at all. Now...I am trying to download album and artist art to store in each of the directories of Artist->Album->files... Are there any Mac based album art downloaders/alternative taggers that can download the usual album.jpg/cover.jpg type files based on an existing directory structure and files? Best, Steve

    Basics: Ripping

    I'm going to have some basic questions, the first of which is about ripping. The articles in CA academy on ripping are 6yrs old. The "what format" is probably more accurate now than ever given the plunging prices of storage. However, while the overall strategy is probably still relevant, the software references seem very out of date. GD3's software still references Windows XP, Vista or 7, not exactly current and no mention of OSX. I'm on a Mac so obviously I can use iTunes to rip to AIFF. Is there some other software that is a superior solution? Thanks!

    Headless Mac Mini: how?

    Hello, I am currently controlling my Mac Mini using the standard screen sharing. But if no display adapter is connected to it, the refresh rate is very slow. I've read many others suffer from this. I read that there is a way to tweak a VGA adapter using a simple resistor and this way have the Mac Mini think it has a display connected to it. To all the headless mac mini people out there: Is this the way everyone is doing it? Or is there a simpler way? Thanks, Nuno
