System Advice required please

I and many other like tubed preamps. They usually have a more musical and natural sound. Maybe a used Rogue? I would normally recommend a used Audio Research, Conrad Johnson, or VAC… but even used these are more expensive than you want to spend.

"even used these are more expensive than you want to spend."

How about the Quicksilver linestage, or a Schiit Freya+?

Just looking over your setup (I like the looks of your amp btw- clean lines) and wondering what your trying to get the most improvement from. Are you using the NUC just for ripping and network playback or coming that with streaming as well?

I used an integrated amp for years before moving up to what I use now- nothing wrong with that as long as it fits your needs. At the time I used a separates- a disk player and music server but no streaming. What are your highest priorities when it comes to your system?
