From the Service department of Audio Research Corporation we received the following message:
Thank you for your patience as Audio Research worked to find a solution for the DAC8 when used with the latest Apple computers and/or their new operating system, El Capitan. In the past, changes to the Apple operating system have been addressed by software changes in the driver. This is seen in the fact that Audio Research currently has posted four different versions of the Apple driver on our website to support these changes. However, the new Apple computers and/or El Capitan were such a radical change that it requires new hardware to communicate with the DAC8. That El Capitan is radically different can be seen in the perspective provided by this audio reviewer as he laments the problems that El Capitan has caused for most manufacturers. (“Apple Messes Up USB 3.0 Audio Big Time”)
Audio Research does not have new hardware that would allow the DAC8 to communicate with the latest Apple computer and/or El Capitan. However, all is not lost. Audio Research has identified an inexpensive USB to SP/DIF converter that will talk with El Capitan and all Apple computers. It is the M2TECH Hiface 2 USB to SP/DIF converter. Please see attached photo and see their website for details: http://www.m2tech.biz/en/hiface2.html. We have tested this product and found the sound to be equal to or better than the sound out of the USB port.
When inserted into the USB port of an Apple Computer running El Capitan, it will provide audio output to the DAC8 via an RCA or Coaxial digital input on the DAC8. This product can easily be found and purchased on the internet for less than $200.
The Hiface Two and other M2Tech products are available in the BeNeLux through Durob Audio. Contact us HERE
