Hi Robert,
I was using a Small Green Computer I7 with LPS over my network with modded Buffalo switches (2) powered by Keces P3. The switches were connected via fiber to each other. I was using a Synology Nas.
I also added a Shunyata stack of Triton V3 and Typhon QRT So the noise floor dropped a ton. I was using Roon server and player. When I got the K50, I used the network, then usb, then got Nordost Valhalla 2 aes and then the Tubulus Concentus I2S. I added a SSD to the K50 and copied all my files from the Synology to the SSD. I now use Roon server and Squeeze player.
At each change there was an improvement in noise, soundstage depth, clarity, and ease of use. You cannot go wrong with the K50! It is three units in one. Server, player and reclocker!
