I don't know how old your Pioneer is, but as bobsticks pointed out: there have been great improvements in DACS over the lifespan of CD and DVD players.... so a modern one will often outperform an older one (even if the older one was far more expensive)....

How much of a difference the NAD would make over the Pioneer is subjective... I suggest you see if you can borrow the NAD from your dealer for a weekend to try it out first...
