Been away for a while, need some help

A Cambridge Azur 851N is a very balanced streamer with good sound quality that can be had for around $1k.

If you want to stick with your Classe gear without needing an additional DAC, you should consider a high quality streamer with a built in DAC for a nice uptick in sound quality from the built in DAC in your Classe processor.  A Lumin D2 or T2 would be a considerable step up in sound quality from the Cambridge with considerably better DAC section, they would be considered end game streamers for most people.  

Not sure if you're referring to the Aries G1 or Vega G1,the Vega G1 also serves as a DAC but the streamer is a bit of an afterthought compared to the Aries G1 dedicated streamer. The Lumins would be considered more refined than the G1 models, and most would agree the Lumins would win in sound quality.  The Aries G2, however would give the Lumin models a run for their money if you're streaming to an external DAC. Better than the G1 but might have a more detailed, brighter (in a good way) sound signature compared to the more refined Lumin offerings. But then again you lose the built in DAC which the Lumin models have and the G2 does not.  

If you want a bit more warmth and natural sound from your system without sacrificing detail, go for the Lumins.  If you want a little more detail at the expense of warmth from your system, go for the Aries G2.  Hope this helps!

Thanks Alexbpm, I did not realize Aries G1 did not have a DAC. At that point I would probably go for the Lumin D2. I have to watch my budget, we are helping our daughter who just started Vet school, plus I want to keep things simple and as much as I know a separate DAC would sound incredible, I would stay with an all in one streamer and DAC. Also the reason I am thinking about going with a nice classic tube integrated like a Primaluna EVO300 or something similar. 

Another streamer in the price range of the D2 to consider is the TEAC NT-505.  You might give the search function a try also, there are a lot of existing threads about streamer recommendations.

My situation was similar to yours in some ways. I had a decent but older stereo that had fallen into disuse - just didn’t listen to a lot of music anymore. We did a remodel of our main living area a couple years ago and in the run up to that I got back into audio and bought some better equipment. Initially had a Blusound Node 2 and experienced exactly what you did - listening to a lot more music for the first time in a long while. My CDs weren’t stolen but they were put away in different places for the renovation and to be honest I have never gotten them back out. 
The node 2 was ok - really I thought better than ok though I often noticed issues in what I take to be the upper midrange whenever the music was intense. But the ability to listen to such a wide variety of music - first with Spotify since that’s what my kids used and then with Tidal - and the mixes and artist radio stations those services provided exposed me to a huge variety of related but new to me music, as did my kids. Bottomline is streaming has amplified my enjoyment of music tremendously and I think you are at the top of that iceberg. 
Just recently I upgraded the Node2 to a Mytek Manhattan DAC w/network card.  I had planned to just by a DAC and still stream from the Node but Mytek was throwing in the network card for free. The difference in sound quality was absolutely night and day. I am blown away with the Manhattan. The sound is so much fuller with much more definition. I find myself counting the number of backing vocalists and learning lyrics to songs I’ve been listening to for 40 years (think REM). 
My experience with Mytek has been outstanding as well. When I email Michal, the mastermind, always emails me back within a few minutes day or night so I’m not sure when the man sleeps but he has always been helpful. 
The Manhattan is a little above your budget - so you might be interested in other Mytek offerings. Full disclosure - my experience is pretty much limited to the Node and the Manhattan. I am sure that there are many other great products out there. I hope you find the right fit for you and your system.
