CPC connectors are pretty inexpensive, the problem is you usually have to buy contacts separately in quantities of 100 per, and even the plated tin ones aren't too cheap. Some vendors do sell them with the requisite contacts included.

I am sure a lot of XLR connectors would work fine voltage wise, but they were not designed for this duty. I use some XLR already in my system for audio and aes digital and sure wouldn't want to mix them up with lines carrying power.

While we are at connecting PSU and (pre)amps what is in your opinion better, just to house transformer in other box or to rectify filter and stabilize in one box and transfer to the other (maybe with some additional pasive filtering)?
Generally, I put the raw supply (transformer, rectifier, filter caps) in the remote box and regulator (or additional passive filtering) close to the signal circuit.

I have the same thoughts myself but thanks for confirmation SY The only problem for me in this case, when you look for connectors, is most are rated for AC (at least power ones) so it is difficult to know if they are ok.

All true, but if you use something with a high AC rating, the DC rating, though unspoken, will be fine. I use surplus Amphenol round connectors, but you can also use octal plugs and sockets. They aren't as bulletproof as the Amphenols, but certainly there's no issue with DC voltage up to 500V.

you can still find 8-pin octal male chasis mounting and 8-pin cable connecting units. easy to cut the holes with a Greenlee.
