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.

 

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

That's the chart I looked at when saying that's what I'd guess, but I can't be certain.  I'm no expert in these things and don't know whether there were revisions I didn't see, different ways of implementing the chip, etc.

 

Edit: The easy way is just to look at what A+ says about your DAC capability.  Assuming it's telling the truth about itself, the DAC advertises its capability to A+ so that the player won't send it anything it can't handle.

 

What is the question actually for DAC-R? I have this DAC for over the year and very happy with it. Mostly using filter nr 1, but more and more gravitating towards nr 3 already. I do not use any upsampling on A+, just feeding USB input of DAC-R with what is actually presented in the FLAC file. For DSD64 playing/SACD ISO using 64bit m-stage algorithm and than DAC-R playing these kind of files as 24/176.4kHz.

 

BTW, WM8742 is not the one in DAC-R, since DAC-R is pure PCM DAC. It's WM8741 IMHO.

Hey, Krzysztof. 

 

I think it may actually be the WM8742, at least if the Stereophile review (and others) is correct:

Edit: Sorry, I did not answer your original question.  It's another DAC-R owner experimenting with A+ upsampling settings and wanting to know a little background.

 

You're right Jud! Mea culpa. So in fact it's DSD stream capable chipset - wondering if Rega could do anything with that updating the firmware ;-) Over the XMOS USB is not DSD capable at all, only PCM.

Hello geeks,

I've just recently upgraded my late 2008 Macbook to El Capitan from 10.9.5 using 3.2.14 A+. Are there any tips and tricks or tweaks for that system to be performed to maximize the sound quality? What I have noticed so far while playing A+ in Extreme mode that task like Python takes some CPU resources - I killed it, but thinking what was that?

@RunHomeSlow has many posts describing how to get Direct Mode back if you care to do that (but it takes a little doing, and you should make a backup first).

 

And of course you can always play with the oversampling settings if you care to do that.

 

I personally always keep A+ on the Extreme setting, but it's easy enough to experiment.

 

Yes, Extreme setting is what I have been using all the time as well. So, does it mean that in El Capitan Direct Mode is no more the case? A+ shows that's enabled together with INT mode? Should I care, don't really know, probably not, since it sounds the same - almost ;-)

Hello,

I am using A 3.5.13 on El Capitan and would like to ask you if there is any chance to drag and drop FLAC files into the Audirvana queue like it was possible in version 3.2.x? 

 

Second thing which it seems to be useful is to add gestures to the UI - instead of hitting < > arrows, it could be just double finger swipe left or right.
