Any availability news or REAL tests of the Sony Walkman NW-ZX1 with 128Gb that is supposed to pair with the PHA-2 ?
More precisely, I would like to know if it offer a real USB-Out that can be used, at 24/192 kHz without Downsampling, with another external DAC ?
if yes, then What cable to use ? A Sony proprietary USB cable ?
The NW-ZX1 will be using a special USB cable, it comes with the PHA-2. If you watch the video and freeze it at 3:58, the NW-ZX1 connects to the left connector, it has a locating pin to stop you using the other micro USB connector. Since the connection is digital, there's no reason to downsample, the PHA-2 can take 192/24 easy.
There's really not much extra to go DoP for DSD files with the NW-ZX1 , the PHA-2 can decode DoP or native DSD.
