USB support DSD64, DSD128, DSD256 hardware solution

Input: Input status display, can be set to USB, BNC, RCA coaxial, AES or fiber input in one.

PLL: Phase-locked loop status display, locked when a valid digital signal is locked.

Filter: filter status, when the type of filter used before, there are seven kinds of optional, can be selected in the settings menu.

Dither: Signal jitter switch status, display whether to enable high frequency jitter to enhance the sound quality, can be selected in the setup menu.

Output: Output mode, display the current analog signal output mode, can be selected in the set menu only for single-ended output, only the balanced output or all have output.

The audio information display area shows: the current input signal type, sampling rate and sampling depth, note that in some input mode, the output sampling depth information may display inaccurate, which is normal and does not affect the actual sampling depth.

Volume display area: display the current analog output signal strength, in dB (decibels), the maximum adjustable to 0dB, press the multi-function knob can make the decoder directly mute.

Seems to be a nice piece of equipment, but nowhere any information. I only found the same info from the sellers.

And the most important information is missing: how does it sound.

It is a little bit to expensive to buy it blindly.

As we see several firmware updates on the dacs, it is important to have a company behind that is visible and supports it.

May be somebody can give some more info.

Would be nice

In the meantime I received my ep3pro.

My first impression is very good.
Clear, detailed and no noise or distortion with my Stax SRM-007t/SR-007

At the moment it is running as a usb-dac for my music server.

Im still wondering why there is nearly no information about it.

It was delivered without any drivers.
At the moment windows reports a missing driver for "Yunyue Audio DFU" when is DAC is connected.

There seems to be an infrared/remote control option, but is was delivered without a remote control unit.
If somebody knows the remote control codes I would be happy to see some info

There are no heat problems. The unit runs with normal temperatures using 10W after the initial warmup time.
