Some thoughts:
1. Don’t rule out tubes. You would be amazed at how good a tube amp can bring out subtlety, texture, and nuance. No disrespect to SS.
2. Buy quality that will last the years. In my main system, I have had the tube power amp (Prima Luna PL5) for 12 years, the preamp/ cd player for 13 years (Musical Fidelity CD Pre 24), the SACD player for 16 years (SONY SCD 555ES), and the speakers (Opera Platea) for 8 years.
Now that I have turned 60, I start wondering when I will need to pull the trigger on the last, great rig.
Once you upgrade the NAD, you will upgrade the EPOS eventually. In the interim, you can hear what an amp a few notches above the NAD can do with the EPOS. (Note: I owned the NAD 320 until I upgraded to tubes).
I would suggest the following top of the line Prima Luna tube integrated as the anchor of your new system. It should last 20 years, if not longer. It is certainly powerful enough for most speakers. PL makes tube ownership easy with adaptive bias. PL probably offers a phono preamp board for this amp.

You have to start somewhere. Good Luck with it all.
