Douk Audio K5 DAC Headphone Amplifier--Let’s discuss it together!

[TheZebraKilledDarwin]

Hello all members,

Recently, we will release our latest dac headphone amp-K5, with USB and optical inputs, optical, stereo RCA, 6.35mm and 3.5mm headphone jack outputs. The USB supports PCM384/32bit,DSD256.
On the basis of our Q4 DAC, we collected many useful opinions and feedback from our users, upgraded some functions and modified some problems now.
Below are the outline sketches, what do you think of it?

Later, I will share its related specs and AP report.

Hi,
if two headphones are plugged in, is it possible to choose which headphone should be active?
Is there an internal jitter reduction mechanism?

Looks nice, very much looking forward to some measurements.

Does the RCA output mean that this will work as a (passive) preamp - is the RCA output level controlled by the volume? I realise that the digital output is not.
