Streamer wanted

Forgive me if someone already posted. I have the NAD C 658. For $1600 it’s a great device. (You may be able to find it a bit cheaper if you have a local store.) I only use the streaming and DAC features as it supports MQA. And it offers XLR balanced (pre-out) if needed. (I have it balanced connected to a McIntosh MA352.) You may not have any interest in MQA but when I "A-B" tested a few, I liked the option (if? when?) MQA grows. It is BlueOS. One very brief review https://www.whathifi.com/us/best-buys/streaming/best-music-streamers And as several have noted, Hans Beekhuyzen reviews, he likes it a lot. https://www.youtube.com/watch?v=c04EJODliww

Happy listening!

I am also about to order a Bluesound Node2i. My reasons are:
I have a great DAC,
I will use streaming for exploration of new music,
has what seems to be an easy interface and apt for my phone,
the reasonable cost. 

@rvpiano, Hey, we miss you over at the “What’s on your Turntable” thread.  Hope you’ll post there more often.  
In answer to your question here, I believe that it will eventually become important to you to ditch wifi; then, you will learn that you should have fiber optic and not just (CAT whatever) between your modem and/or an audio-purposed built switch and your streamer (whichever/whatever your streamer is); and then, after that it will become important for you to have fiber optic between your streamer and your DAC (that is if you don’t want your streamer and DAC in the same box).  Until more affordable DAC manufacturers put connections on their products like the fanciest do, you can either convert this link to fiber with adapters or go with good USB from streamer to your favorite asynchronous USB DAC.  
You have received a couple of (very reasonable cost) suggestion here that get you most of the way there to what are inevitably important ways of your looking at  and listening to digital. 
In the mean time if you just want a WAY better coax streamer consider this:

if your favorite dac has USB go with the optical setup recommended by other members above.  

Also, consider getting Roon.  But that is a separate thing.  
The people on here recommending Bluesound are either afflicted with hearing loss or don’t have systems as resolving as yours.  You already know even Arcam beats it with your DAC.  Bluesound is fine for a second system or something but i don’t believe it’s what your after for your level of listening.  

I have the Node 2i connected to a Schiit Audio Loki Mini. 

Spiritofradio,

I appreciate your missing me.
Since I got a wonderful DAC (Benchmark) and high res audio disc digital extractor (GeerFab,) I’ve been more in the digital realm and neglecting records lately. As the novelty wears off, I’ll be getting back to them.
As far as the streamer goes, I’ll see if the Node 2i is any better with the Benchmark than it was with the previous DAC. I’m actually fairly pleased with how good a job WiFi does. I just want to investigate hi res streaming which my Arcam is incapable of.
