The streamer is the modern day "transport" It's vital to great playback, plus you want an user interface that appeals to you. My Aurender N200 sounds great, I also demo'd Innuos which was good too.
I listen to a bunch of my favorite radio stations through it, have Qobuz and Tidal , have a few hundred CDs stored in it's SSD....it's a versatile and awesome machine. I sold a preamp plus cash to buy it and it was worth the stretch. I was going to buy something smaller, with less features and I'm glad I didn't. It's the center of my digital universe.
