Playback Designs has said for sometime now that there will be upgrades for their earlier products. And here's what they posted on their web site on the upgrades to address the Apple USB driver and add Quad DSD to the earlier Playback Designs products:
"Upgrade Kit Coming Soon:
Following our tradition to always support our loyal customers with their existing Playback Designs products we are preparing an upgrade kit for all 5- and 3-series players and DACs. This will add the capability to play quad DSD files which can be generated and recorded with our new and upcoming "Pinot" A/D converter, and also address the issue with Apple's USB driver. The upgrade kit will be available later in 2016."
This is very good news for PB customers
Unfortunately I'm not.
By a twist of fate I ended up with emm, which is reluctant to give their customers a fair go.
I have had success with the iOS Sierra system, where my USB-XII box has been finally recognised through Audirvana.
In saying that, I have also ordered the new version 3 box, expected end of this month.
The new USB-XIII box is superb, as it can rip the DSD layer of the SACD directly from the disc as a file onto a computer. It can also output single DSD on AES/EBU and SPDIF.
This may be going slightly off topic, but thought some on this thread might be interested in this new Positive Feedback review of the latest digital system from Playback Designs. Seems the reviewer finds it to be a step up from their previous top of the line.
BTW after a year of waiting I enjoyed what Neville said about USB-X2 functioning with OS Sierra, I did the upgrade. I initially thought mine functioned when using JRiver but I spoke too soon so good to know about Audirvana.
Well here is a revelation that I just discovered. Previously I had my USB X2 box working fine with Yosemite as I switched back from El Capitan to Yosemite but then an auto update to Yosemite screwed my box once again and I have a USB X3 box on order. After upgrading to Sierra OS after Neville said his USB X2 box worked after the upgrade I found mine still did not. Then I had this brain wave to upgrade to ther current version of JRiver (MC22). I was running MC21.
After the instal was complete I turned on my digital side of the system and using the USB X2 box I am now completely able to play any HiRez PCM up to DXD and also DSD up to DSD128. So the only thing the USB X3 box will do is to allow me to play DSD256. Also Andreas tells me the USB X3 box is also powered unlike its predecessors
