Paired my Zidoo UHD3000 with an external USB DAC from Topping. The model is E30 which can decode DSD, DFF files into PCM - DOP. The E30 is using the AKM 4493EQ chipset and is using the XMOS interface which is very important to ensure this DAC is recognized by UHD3000.
So far, I have no luck getting multi-channel DFF files to play on the Zidoo UHD3000 via the internal Music Player (version 6) and not a surprise to me as I have had heard many problems with Zidoo official Music Player app to get DSD files to play.
So I guess I have to use a software player which can allow me to use ASIO driver for multi-channel reproduction. True enough, Foobar2000 on a Windows laptop did the trick, but I digress since it will be more of testing Topping audio prowess rather than using Zidoo UHD3000 built-in DAC which advertised to work on multiple audio formats but it didn’t. Bummer!
FWIW higher bitrate like 88.2Khz up to 192Khz encoded in Flac and Wav played flawlessly. There are a few steps that need to be invoked before Zidoo UHD3000 can recognize the Topping E30.
The reason I have gone for this cheap DAC is the provision of a separate power supply (5V at 2.1A) instead of relying on a single USB In which provides both the power supply and the signal. We all know how notorious a USB signal can fluctuate in its current which will most definitely messed up the DAC conversion process. Of course, I am also attracted to the AKM chipset of E30.
