Mid-Fi, Hi-Fi or.....?

I wouldn’t be too concerned about mid-fi or hi-fi. If you trying to step up to next level, try as many Integrated’s in your home. Sometimes you end up spending 1.5x to 2x for minimal gains…it that worth it, only you can decide. 

I think your NAD is a significant improvement over most vintage gear...and I love vintage gear...

@zlone  Thanks for the info! I had read about swapping out the jumpers and bought these, hope they are decent, just have not installed them yet.  Is it easy to do?  Also, what pre-amp did you use?  Thanks again!  John

agree with the jumpers, I used AQ upgrade jumpers on my NAD and others...
