Another KISS thought. It’s the all in one box rather than a separates approach. These are shockingly good too!

Wow, didn’t intend to create a firestorm here. I’m not interested in changing my whole system. I have looked at the blue sound node and even though somewhat expensive for a “try it out” . I’m looking for one used for a reasonable price. Again I’m not looking to replace my system, just looking to add to it. Thanks to all. 
 I’m happy to provide some entertainment to some of you!!! Joke!!!

Welcome to the audio jungle.

You will find out this happens a fair amount here.  There are even threads talking about why threads deteriorate into testy exchanges.

Like I said before look for a Sonos gen1.  You can find these for super cheap.  They dont sound as good as the BS node but it will allow you to experience streaming with a really good interface.   This will give you time to survey the landscape and do trials with streaming services, understand network,  with a minimum cash outlay.    Then if you find its for you then dump real cash on a nice streamer & DAC.

I also worked the board for many well known artists visiting concert venues in my area. Just a few to mention a few, chuck mangione, Maynard furgison, and many others.

That is really cool.  I was and still am a huge Maynard Ferguson fan.  I was the weird kid in grade school/high school who preferred rocking out to Maynard's "MF Horn" albums instead of the popular rock and top 40 artists.  His "High Voltage" period is a little cringy, though...

Back to streamers, I'll also recommend the Bluesound Node as a starter.  I know you mentioned looking for used.  Just an FYI, there is a difference in processors (1 GHz in 2i vs 1.8 GHz with 64-bit support in Node) and a better DAC (192KHz max on 2i vs 384KHz on Node).  I can't personally speak to the sonic improvements due to those differences.  I own the newer Node model and have only casually listened to the older 2i at my dealer.  I'm pleased with the sound.  The reviews I've read comparing Node to Node 2i give the nod to the Node because of the better DAC.  I will hopefully be getting my new preamp soon with what I believe should be a higher end on-board DAC and am curious to see if using that DAC with the Node makes any discernible difference.
