OK I think the Monitor series is leaner sounding than the Classic series. The Classic series is great because they are linear and coherent throughout but still maintain body and fullness throughout.
Ayre is reputedly lean sounding although the Codex uses the double diamond stage which is meant to be fuller sounding. Ayre gear works well with Transparent or MIT which both give a fuller sound - I prefer MIT as I find Transparent can sound thick. Ayre themselves recommend Cardas cabling - so maybe try those perhaps from the older range as opposed to the current Clear range.
Did you try the NBS in the pre to amp position? I am guessing that if you use the Transparent Ultra's you have from Ayre Codex to pre and the NBS Classic series (if not the Monitor you have) from pre to power amp (what power amp do you use?), you will be happy. Try that and see how it works out.
