No, the Scap(preamp) to Scap(SNAXO) interconnect is a standard SNAIC4; even though it does not carry secondary power between the two SCaps (and I would be in breach of forum rules if I took this any further ).
What I was asking Richard about was the interconnects between the SNAXO and Power Amps.
No, it’s for when you use the smaller Naim amps in an active system. The SNAXO can have difficulty driving more than one SNAIC here without instability - the active leads are easier. You can, of course, use one between the pre-amp power supply signal out and the SNAXO power supply signal in, but it’s not necessary.
This is why recently when i had to disconnect my active system to decorate behind it, i put labels on them to stop any confusion. The Naxo 3-6 i left the din plugs connected to it and labelled the XLR’s to the 135’s like for example LEFT (speaker)… CH 1 or 2 (in 135)… MIDDLE (drive in speaker). Don’t even have to look at the manual.
