Your NADs are a 15 year old design, and if used, may need a going through.

I suggest a modern class D or Purifi amp. Disregard the old reviews and audio snobs. They have come a long way.

@zpatenaude37, my apologies for my lack of reading comprehension.  Total swing and a miss on my part.

There is a reason you always see B&W speakers with McIntosh or Classe amps. I have also found that Nordost cables are a little on the cool side. Adding more cool sounding gear with the B&W’s might not be the sound you want

You are on the right track with Parasound. A pre-owned pair of JC1s would make a significant difference to your system. As others have suggested, I would address the power amps before doing anything else. The 803's need both power and refinement and the Parasound's have both. Pass do as well and would be my preferred choice at retail prices. But as you are on a budget, I would look at the pre + series Parasouds pre owned if you can find them. Classe power amps are also a good match. If you are looking at buying new, the Rotel Michis work very well - but they are a little more biased towards power than refinement.

@sbank do you think if I can find a good price on a 10-15 year old Pass Labs pair, that would be a good deal? I'll still probably wait it out at this point, but maybe stay posted on the market for good deals.  

Yes.

I also like the Classe suggestion. They are another Canadian company that gives great value relative to their cost. Used ss amps from them could be a great option for you. Cheers,

Spencer
