@joeyfed55 - I’ve been through a similar journey. Initially I had a Node 2 (prior to 2i) but wondered how much better it could get. I ended up buying a Mytek Manhattan II DAC w/network card. I got a little bit of a deal during early COVID days - just north of your $5k target. I really couldn’t believe the difference. The Node sounds good but the Manhattan is just amazing. Soundstage, space between instruments, being able to understand lyrics I’ve been listening to all my life (think REM).
The Manhattan II is being replaced by a unit that will act as a Roon core - my unit is just Roon compatible. I am very happy with Mytek, but my point is broader. I would strongly encourage you to sink the additional cask into digital - for me it was well worth the effort.
