To get the best out of the N20 you will need:
1. Get a 10mHz 75 Ohm clock, something like After Dark or Chinese will work, no need to spend $1000s, but a quality 75 Ohm clock cable is essential.
2. Hi-End power cable, $3-5k. For DAC too.
3.Silver USB cable 1.5m
4.Purple Fuse. For DAC too.
Concentrate on SSD playback until you get it sounding right before you start messing with streaming. No need to upsample. Switch DOP off if you have DSD files.
If you are considering changing your DAC the Terminator 12th Anniversary has a built-in clock output designed for the W20SE but it should work with the N20.
