I also have a Bluesound Node for streaming digital out to a PS Audio Directstream DAC. I was going to upgrade the streamer (was looking at Innuos and Aurender) but neither has support for the two services that I use, Amazon music and Idagio. So instead, I upgraded the power supply to a TeddyPardo LPS. The difference was significant! Some feel that it's ridiculous to spend as much on the upgrade as the unit itself costs, but I'm very happy with the results. My point is, if the streamer doesn't support the services you use, then it won't work for you! BTW, the sq from the moded Bluesound is slightly better compared to the same recording on a cd played on my NuPrime CDT-10 using the I2s output; in other words, pretty darn good!
