As the illustration shows, you should use the single ring Burndy for connecting Input 1, and the double ring Burndy for Input 2. Make sure the ringed ends are closest to the NDS.
As you’re using an NDS and 555PS, the S-XPS Burndy is not required here.
This illustration shows that the S-XPS cable (which is normally used for the Naim XPS DR) can be used for Output 1 of the 555PS DR.
Why?
Since I have both the S-XPS cable (smooth black) and the 10 pin Burndy cable at my disposal, I was wondering which was the best cable to use in terms of quality.
If I connect using the 11-pin S-XPS and the other 7-pin cable will I misuse the 555PS DR with the NDS?
Or will it work the same way correctly?
I think it’s interesting to clarify if it’s obviously possible.
I couldn’t say for sure I’m afraid. Possibly an error as the S-XPS is usually only used when the link plug is fitted to the other socket and you’re powering with either an XPS2/DR or XP5XS power supply. Do you know which rev. of manual it’s from? Probably best for Naim to clarify.
I’m using the S-XPS on output 1 of the 555PS DR, because I’m powering a NAC-N272 with it.
Interestingly, I’ve tried the experiment the other way around - connecting a Burndy with a red label (10 pin) between both, and that worked - 50%. The 272 got power for it’s streamer functionality, but not for the preamp section; so there was no sound. Or at least, that’s my hypothesis and the observed effect.
So using the right Burndy is a must - each pin has its function. I believe the 11 and 10pin Burndy share some pins, but not all. Different combo.
