You have been on ASR review web site again .
totally disagree starting from the router ,the wall wart garbage has to go just ads more noise , I bought a LTA LPS power supply ,and a decent $600 Ethernet switch ,decent power cords , and quality Ethernet cables, USB , and I2S cables
Everything counts . The Terminator15 dac is very good and resolving
and my new Swiss Merason Dac 1-MK2. Is probably one of the most analog sounding dacs out there ,both dacs are far better then Anything under $5k. Having heard literally over 100 dacs over 20 years technology in digital has Greatly advanced. $5k on up is A respectable reference point To start ,this is just from my experiences and IMO.
