I had the same dilemma as you as Naim recommend DIN terminations.
As I was so skeptical, I had to try both ways to see actually what they are recommending has any validity.
I've tried DIN terminated Chord Crysalis and Cobra 2 on various spots in the system. When RCA are used off the Naim source ( I own CDX2/XPS2 ) is used with non Naim preamp/amp, actually my regular ICs ( NBS ) worked better than either of Chords recommended by NANA. Luckly, XPS2 has a set of RCA out so, I did not have to use DIN/RCA adaptors for this. ( Cardas and Chord both make those )
So, I'd think that as long as you are using ML, you can still experiment with ICs off your Naim source. ( there are lot better ones out there than Chords as they sound pretty mundane in most non-Naim systems I've tried. ) Which ICs are the best for your system depending on what you are looking for.
It's when I start adding more Naim electronics, Chord came out of ahead of my normal cables. I still do not use Naim amplifiers ( use Jota monoblocs with XLR inputs ), but the connection between Naim preamp and amplifiers, DIN/XLR Chord Cobra 2 was more truthful to the Naim sound I love leaving NBS rather disjointed in the system. They, too do not terminate their cables with DIN, so, I had to use Chord DIN/XLR adaptor for this experiment. I've a feeling not too many manufacturers are keen to the idea of DIN terminations. Audience, Cardas, Kimber and Nordost offer those, however.
Get a DIN/RCA/XLR adaptor and you can still audition various cables as you do with any other gear.
I believe also, Naim will fit RCA outs for a charge. If you are planning to keep CD5, might be worth it to have it done since no adaptors would be better.
