Yes, using the LH Labs Geek Out 1000 with A+ volume set to max 100% and using external pre-amp for volume control. There is no volume control (anymore since latest firmware) on this USB DAC. DSD playback worked fine in A+ 2.x (not sure which version, possibly before Tidal support).

Or was it before the DAC firmware update?

Is there anyone who has the same DAC?

Can you try with Integer mode disabled? If the DAC FW had become incompatible with it, though should not be.

Some AudioUnits (e. g. Goodhertz, Ozone6) still don't work in realtime mode over Firewire to Mytek-Stereo192 DAC.

Working over USB - is Firewire no more supported?

I am reporting this problem since A+ 2.5. Someone else with this? (btw works fine in Fidelia over Firewire)

A+ 3.0.6 is out now: Some Audio Units still don't work in realtime mode over Firewire. Fidelia can handle it, but I still like to stay with A+ ....!?

A+ manages the DoP 1.1 implementation of the Mytek Stereo 192-DSD. This very mode made for it specifically to play DSD128 while it is limited to 192kHz. And this uses 4 channels for playback, making it incompatible with stereo only AudioUnits in realtime config.

This is already done: just (re)start Audirvana Plus before leaving.

The license check is done every 2 days. The grace period means only there can be no check during 60 days.

 

That's great!  Thanks.

 

I am impressed with the speed of the updates and bug fixes, you must not get much sleep.

I replaced IOAudioFamily.kext of Sierra 10.12.4 with your nice one of 10.11.6 El Capitan by using Kext Wizard app. It's visual (without commands) and simplest installation procedure. The result is the same. Now Audirvana plays in Direct Mode. Every thing look like perfect include Sierra. Thank you again.

@damien78 your responsiveness to our many requests is much appreciated.  I'm pretty sure 60 days will work for me (and i can always reinstall 2.6.8 if you disappear from the face of the earth).

 

I'm also in the camp of 3.x sounding a bit better than 2.x. 

 

Thanks for continual feature and SQ improvements.

@damien78 Thanks for the information. I still don't understand why the mentioned AU's work well with USB 2.0 but don't work with Firewire (both to Mytek 192, PCM only). ) Must be related to FW, no?

Would need to check, but if DSD128 is not available in USB? this explains.

BTW, have you tried with the option "use as stereo only" activated?

Yes I tried both, "stereo only" and "4 channel" -> same result.

My 'Maximum memory allowed for track pre-load' seems to have stopped working.

 

I stream DSD256, and usually have around 7-8GB processing the transcoding as seen in Activity Monitor. However since this evening, no matter how high I set the pre-load, it's only allocating 1-2GB and not loading the music quick enough anymore. Is this a problem somebody else has discovered and fixed? Tried resetting the Mac, not sure what else I should be doing.

Ive noticed a problem with lagging dsd 256 playback which was never an issue for me before, I will check and see if my preload is allocating only 1-2gb. it worked no problems at one point for me?

@damien78 Does the A+ check and sends out the date needed ONLY to check the license or it could add something else?!

Thanks for checking. I've managed to pinpoint what is causing the problem. Ever since I'd set my pre-ringing from 150db to 7db, the DSD256 stream had only been able to load 5 seconds every 10 seconds or so. It begins to load at around the same speed of the song once set at 16db. If I increase pre-ringing to maximum at 200db, it loads very quickly.

 

Is it normal behaviour for low pre-ringing to have an adverse effect on the transcoding speed?

Not Damien, but I'd suppose just like it's done for years it would do a check for whether you have the latest available update and ask whether you want to install it.

I think you are talking about the steepness setting rather than pre-ringing, right?

 

This is sheer speculation on my part: Since greater steepness more efficiently eliminates aliasing, perhaps lower steepness means the filter has to calculate output for aliases that aren't present with a higher steepness setting, thus taking more time to do so?

I have a Geek Out.  The next evening or so is busy, but I'll try to check this weekend.

Hey Jud, many thanks - I appreciate your reply. My mistake and well spotted - my brain isn't working properly this afternoon! 

 

It is indeed the steepness I was talking about. I was researching the forums and found a few recommendations to use a lower steepness setting for a warmer sound as my current set up is quite bright (Gustard X20 Pro > IFI ICAN Pro > Sennheiser HD800S). Have I been doing the right thing with the steepness setting to try to reduce the harsher frequencies slightly?

These filter parameters are all interactive.  Lower steepness may start cutting a little earlier, yes.  Something else you can try in addition to or instead of this is reducing the cut-off to, for example, .97 Nyquist or some other value lower than 1.00.

 

What is your pre-ringing setting?

Thanks, I'll give those suggestions a try. Currently my cutoff is at 1.02 and Pre-Ringing at 0.86

I don't know whether this will affect your perception of brightness at all, but you could try moving the pre-ringing setting closer to or equal to 1 and see whether there's an effect, and if so whether you prefer a higher setting or your original one.

Hello,

 
Audirvana has SysOptimizer to shut down MAC processes that negatively influence music (we all know). These processes are:
 
Disable Spotlight
Disable Time Machine
Disable Detection of Devices on USB
 
So far, after opening Audirvana, I execute a Script of Tie that closes these processes:
 
Disable All
Disable Termination Daemon
Disable Sleep Mode
Disable Hibernate
Disable Mission Control
Disable Time Machine
Disable Spotlight
Disable Launch Control
Disable Dashboard
Disable Notification Center
Disable NapApp
 
I have noticed that if I do not execute the Mooring Script the sound is different ... could it be that with the SysOptimizer is enough?
 
Thanks

Hi Damien,

 

I use the Apple remote to control Audirvana. I can use the play/pause button but there is no way to stop Audirvana with the Apple remote.

Do you think you could add the ability to stop Audirvana with the central button of the remote in a future release ?

 

[Bob Stern]

A "Stop" popup appears if you hold down the play/pause button for about 2 seconds.

Hello guys,

 

I would like to know if there are any known issues with Audirvana+ 3 with the DAC embedded in the preamplifier Rotel RC-1590. I am interested in playing PCM and DSD64/128.

 

Thanks!!
