If you like it, the trick still works In Mojave 10.14.3 with A+ 3.5b11

I am using it in Mojave, but not with the beta.  Good to know, thanks.

My reading indicates the Oppo supports input rates up to DSD512.  If that's correct, I would try upsampling to DSD256 (maximum available with Apple equipment feeding the DAC), if the iMac can handle it.  If it can, try the B8, B7, or C modulator.  If it can't, upsample to the maximum PCM rate available (I believe 384kHz with the iMac).

 

For Sox settings, you can see whether adjusting pre-ringing up or down from the default sounds better.  I also personally like to adjust the filter length as short as possible, but you may find it doesn't make a particle of difference.

 

I'd suggest leaving the other settings at default.

Jud, thanks so much for taking your time to research my issue. I followed your advice and seems to sound great. The OPPO205 DaC section has an "Up-sample DAC input" that I leave it on, I tried off but I do not think I can hear any difference.  Nevertheless I am wondering if the Audirvana is already upsampling to DSD256 and the Oppo is upsampling too the input coming from the Audirvana,  is this double upsampling too much or redundant??. Once again thanks

DACs don't upsample DSD, so if you send DSD256, the DAC won't touch it with any upsampling filters, just convert it to analog at the final analog filter stage.  (In some sense this is "upsampling," since analog has an infinite number of "samples."  But it's not what people mean when they talk about upsampling.)

 

Edit: There is also a filter to remove the ultrasonic DSD noise.

Once again, thanks so much for your help and patience. Have a good weekend

Hello all,

Wondering if anybody on a Mac Mini with no screen attached, using Apple Screen Sharing
is able to put A+ in his login items, and see it filling the screen when open after a restart ?

Mine opens like first image, but i have to ALT with green button, to have it like before filling the screen
like a want it in picture 2. All that was possible and still is with 3.2.16 on Mojave.

Is there any news out there about a release date?

[RunHomeSlow]

It should be going public beta... real real soon

I have a DirectStream Junior DAC which, to my understanding, upsamples everything to DSD 1024.  I asked Ted Smith this question, and maybe I misunderstood the answer, but to my knowledge he said that the DSJ (and DirectStream Senior) do what they do regardless of what is sent to them DSD or PCM.  I was asking in reference to HQPlayer.

The DS upsamples all PCM or DSD to 28,224 MHz.

The maximum DSD input is DSD128.

IMO, it is not a good match for software upsampling (A+ or HQP).

Thanks. I should know better than to make blanket statements, because there is always an exception.

I just like the way HQPlayer sounds on the DSJ as the back end for Roon. Much better than Roon by itself 👍

The filter to remove the ultrasonic DSD noise is in Audirvana?

It's in the DAC.  Sorry for not making that clear.

 

Part of conversion to DSD is "noise shaping," which pushes noise higher in the ultrasonic band. The DAC then has a filter which removes this noise.

How will we know when that happens?

Surely have a link here 😀

Thanks, I am looking forward to it.

Here it is !!

The public beta is now available!

To get it, first activate your Audirvana Plus 3 license key for the 3.5 by going to this page

It will then give you the installation instructions, and the link to download the beta.

 

And enjoy!

great - looks good at first glance! looking forward to testing it!

 

First question: will iZotope SRC be back?

[AudioDoctor]

Giving it a go now, has Direct Mode disappeared?

 

never mind, I found it.

The old iZotope (no update since 2011) algorithm has been deprecated in favour of SoX that gives better sonic results, especially a larger bandwidth.
To ease the transition for current users, I'll add again choice for iZotope in an upcoming beta, but this will be available only for users upgrading from a previously purchased Audirvana Plus version.
If you find SoX to be a bit too bright, you can tune it by first setting its phase setting around 65, and you can also look at decreasing the filter slope by reducing the "bandwidth" (it is exactly the bandwidth at 0dB).

Not at all, but you need to have the right kernel extension from El Capitan

Thanks Damien, I do, and it's installed it was just me missing it in my excitement!

I may use A+ different than most folks.

 

Up until this beta, I would just find the file folder of flacs that I wanted to play and just drag the folder from my external hard drive to the A+ icon in the dock - the flacs in the folder would load automatically and start to play. Simple. (I don't maintain a library on A+ and just drag the folders (or individual flac files) as I need them.)

 

When I try that with a folder with the beta, I am getting this error message: "The document “Kenny Wheeler - Deer Wan (1978) [2016_HDTracks 24-192]” could not be opened. Audirvana Plus cannot open files in the “folder” format."

 

When I try to just drag a drop a single flac file, same (failed) result: The document “10 - You've Got To Stand For Something.flac” could not be opened. Audirvana Plus cannot open files in the “FLAC audio” format.

 

If this is true, that may be a deal killer for me. But probably I am just stupid. How do I play folders full of flac files or individual flac files now? Is drag and drop no longer an option.

 

I also tried dragging the folders/files into the play cue window - that still works on the A+ 3, but not the beta, it seems.

 

Please advise.

 

Thanks!

 

I am on a Mac (Mojave 10.14.4).

I would still like to be able to sort Qobuz albums alphabetically...
