Forunder $7k the T+a 200 dac myself and many say by far best in class it beats dacs much more expensive . The innuous pulsar latest mk3 or 4 you can get forunder $6500 which is top notch and better interface then Roon sounding better
to not have to use Roon. Buy a decent ethernet switch Ansuz or innuos
and for sure quality Ethernet cables , and important buy a quality LPS power supply at the router ,the$5 junk wall wart that comes with the router- modem comboinduces a lot of noise , linear tube audio $700 on Audiogon by far the best in class and can go upto 8 amps routers are around 4amps look on the wall wart today most are 12 v and comes with a very high quality DC cable to router. Many people forget this ,a Big Mistake.
