Upping my digital game

Let's say I wanted to significantly up my digital front end. See my system profile- note the Sim 260D (pre-neo) of which I have no complaints sonically.

Here's the features I want-

1- play digital discs
2- play hi-Rez digital sources
3- future digital flexibility

I like the big boned Sim sound, feeling it mates well with my analog front end.

Thoughts- Sim Neo 260D

Benchmark DAC 2

I've heard the Sim 650d which funds permitting would easily be a prime choice. But at what $9,000 MSRP, not happening. Budget is $2,000 - $3,000 including any necessary cabling.

Suggestions? Not adverse to used or as some would say, Pre-owned.

Thanks-
