Marcin,
As you know, I decided to go server way many years ago after my first good experience with files and your Jplay in hibernate mode.
Then came Aurender S10 followed by his more mature sibling , W20.
The W 20 is battery powered so my first suprise was the impact of good power cord.
Then I was even more suprised when I installed your Lan cable between the wall and W20, the cable which is out of function when music is played. I could even hear the difference between standard Jcat Lan cable and the reference version, which I could hardly believe
Next step was the usb cable to my Lampi without power supply , so called " unpowered" usb.
Your Jcat unpowered reference has in my opinion best price / quality ratio .I found better but also for much more dollars ( or rather Polish zloty
)- Apricity usb cable, still unpowered.
My next step was upgrading my B7 to the new Amanero board with more precise clock , wich I decided to downgrade to the old less pricise version after two weeks or so because the sound became too digital and less analog to my ears.
I do not have a NAS and do not intend to install one unless it will be obvious that the Ethernet DAC will be no brainer.
Just my 2 cents.
As far as vinyl, cd/ sacd and files playback are concerned, every source has its own characteristic, I am unable to decide which one is better.
For the convenience and quality I buy hires and native dsd, for the content old sacd recorded with analog mikes and vinyl- because if well recorded - is closest to the soul of music imho.
But I listen mostly to files, to vinyl only on weekends when I am more relaxed.
Sacd's mainly when I buy a new disc before I make a dsd ripp with my Pioneer Bdp 160.
