nokz:No nad is rubbish compared to say naim or cyrus or leema but its good enough for the 685s i own two pairs of th b&w,s and the are great but a budget speaker so a nad pairing would be ok with them for the price!
Sorry but your comment is a load of c**p!
NAD isnt rubbish but it may NOT be to your taste as Primare and Naim isnt to my taste! Everyones different!
It's the same with all seperates whether they cost £10 2nd hand or £5k brand new! It's all down to personal tastes, hearing and musical tastes etc...
If one person loves the Naim gear say with Rega or Neat speakers then great but it's not going to suit someone who loves rock solid, deep and punchy bass therefore they may go for the Leema, NAD, Rotel or Arcam seperates paired with B&W, Monitor Audio or Kef speakers etc...
As said above the B&W 685's are probably some of the best budget to midrange speakers you can get (mainly in the £500 bracket) along with the M/A RX2's and the EB Scoustic EB1's. Pairing those types of speakers with £1k amps and CDP's or above will work very well BUT it probably won;t work as well as looking at speakers like the ATC's or above.
