Another vote to start with a BS Node 130 $499 new and use your dac. It was less than a year after I got mine, I bought a better USB cable and then I bought the Teddy Pardo LPS. The cable made a big difference and the linear power supply made an even bigger! I think this combination gave me at least 80+% of what a $6300 Aurender streamer gives me in sound quality.
All the best.
