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

I had that very same integrated for a number of years, it is very good. However, I wanted to see if I could do better and added a separate preamp, bypassing the one in the NAD. This was a significant improvement and removed some of the grain in the sound. It really comes down to your ears, and budget of course. If you are happy, then it’s hifi!

BTW, these offer a nice improvement to the sound over the metal jumpers on that integrated:

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
