Wanting to upgrade my streaming sound quality.

I’m using the balanced outputs and an Ethernet cable direct into my router. I just downloaded the Qobuz app and will give that a try in the coming days. Streaming does lead to music you’ve never heard before. Just play one song and you get a bunch, that Tidal in my case, recommends for you. 
 

I thought my streaming before was decent using my iPad through the dac in my preamp but this is a huge improvement. Over the years I’ve made upgrades and changes that helped or didn’t help the sound of my system but other than changing from my old ADS L810 speakers to my Aerial 7t’s, nothing has made this kind of difference. I’m not a very good writer or reviewer of audio gear but this change will have me playing a lot less records.

OP,

My Aurender W20SE steamer has been life changing. 

Just saw this thread and glad you are enjoying the rs150b.  I borrowed one from my dealer for the week and think it's really, really good.  My standard combo is an Innuos Zenith MkIII going into a Border Patrol DAC, which is a great match for my Volti speakers.  The HiFi Rose is not as lush, has a bit more bass and a bit more detail.  Most importantly, it's an engaging listen.  Without getting into the R2R vs Chip wars, the implementation on the ESS chip here is obviously really good and so far I think it sounds as good as any of the other options that I've heard at this price point, and those don't come with all the extras (touch screen, Rose Video etc).  I think you made an excellent choice!

BTW--some of the comments on DAC being 90% are just off.  I have a Zen Stream (which is definitely better than the Bluesound Node 2) and when I compared that running into my Border Patrol DAC vs the Innuos Zenith MKIII into the Border Patrol it wasn't remotely close.  I think buying one box at this price range makes a ton of sense. 

Something to consider with an all in one streamer is Dirac Live.

Dirac Live resolves the soundstage with improved clarity and intelligibility with all instruments and vocals. With the room correction aspect you'll experience deeper and tighter bass free of resonances throughout the listening area, with greater transparency and the removal of distracting artifacts.

The miniDSP SHD is a good example of a streaming high definition digital audio processor with excellent DACs. Dirac Live uniquely combines frequency response correction as well as impulse response (time domain) correction in the digital domain. Fixing time domain anomalies is an impressive advancement for any audiophile system.

The only downside is the increased complexity and effort needed to fully integrate Dirac Live. So having excellent dealer support is important.  Deer Creek Audio is an authorized miniDSP SHD dealer.

For others still on the fence about upgrading their digital, I just replaced a significantly more expensive Aurender server/streamer with a Roon Nucleus paired with an IFi Zen Stream (as the Roon endpoint) connected to my DAC via spdif.  While this set up took me a while to figure out, the improvements in sound quality, system stability and the user friendliness of the Roon interface is proving to make this one of the best decisions I've made in my 25  years in this hobby.  So for less than $2K, this change has transformed my sound quality and listening enjoyment. I wish I had made the change to Roon years ago... it's a revelation on many fronts.
