I know how you feel. I was always a vinyl person until a few years ago, but circumstances changed and I now find myself embracing the benefits that digital music provides.
Unlimited music for one low monthly fee is hard to argue with. I will always keep a few hundred records and a turntable, but for me it will just be another option.

If you can find a used Lumin U1 mini for $1200 to $1400 or an Auralic streamer with femto clock for $700 to $800 used. I found MacBook noisy as a streamer. A nice R2R dac since your coming from vinyl. $1500 for a new Audio Mirror dac or if you can find a used one even better. MHDT Orchid dac new $1200 or $900 used if you can find one. Rolling tubes in the Orchid is fun and beneficial. I just got into streaming 4 months ago. I kept my budget around yours and haven't missed my turntable. I have a Auralic G1 streamer,  MHDT Orchid dac, but did add the RME adi-2 dac when I'm in the mood for something a little different. I'm a vinyl person and it cost 4x what I spent on streaming and my turntable has not been used very much lately.

I deleted my prior post as I hadn't read your original post carefully enough.

I don't have an exit planned for vinyl at this point, but I was looking for a listenable digital solution for listening to new music, casual listening, etc.

The first thing I tried was an Innuos Zen mini which has a DAC built into the Innuos (one box solution). The results compared to my vinyl setup were inadequate for my needs, with the sound quality too low.

A few years later I tried and purchased an Innuos Zen III in combination with a Line Magnetic lm 32 dac. This provided sound, that while not as good as my analog setup, was much less expensive, listenable and quite good. I also used ROON for this setup. I don't think it significantly affected the sound quality, but it made a significant improvement to the overall experience.

This two box solution might work for you because the two units are stackable. You could improve the sound quality further by using a Innuos Zenith and/or a better DAC, but these components fit the price point in my budget for digital as well as being available locally.

You can see a picture in my system which is posted. There is also a Linn CD player sitting on top of the Innuos and LM units.

Best of luck with your search.
