Regarding the cable photos, the bottom one is the SNAIC 5 needed to connect the Hi-Cap to the 32.5 with the band at the 32.5 end as HH says. The top cable is an interconnect to connect a source to the 32.5.
Regarding the connection to 250 I would move the blue dot 1 socket left (i.e. use socket 1 or 2). Socket 3 is intended to power NAXOs or pre-amps that only have single rail power (e.g. NAC 32). So usually socket 3 OR socket 4 is used to power the preamp and sockets 1 and 2 used to provide the signal to the power amp, the recommendation being to use socket 2 with a single power amp.
As Luther suggests, use Hicap socket 2 to connect to the 250. I originally suggested socket 3 as that’s what you’d use on a more modern Hicap.
Your Snaic lead does look a bit dubious with the blue insulation and I wonder whether it’s genuine. The more modern black Snaic 5s are significant better, which may be a good idea down the line.
I also have the manual but I suffer with certain things visually the lines of dots and dashes are like an optical illusion and blur and start spinning when I look at them.
Snaps socket 2 carries power, so connect this to the 101 using a Snaic 4. Label at 101 end. Connect Snaps socket 1 to your preamp using a 4 pin to 5 pin interconnect.
I’d suggest that if you gave your thread a sensible title such as ‘Naim NAT 101 connection help’ rather than a silly title, you’d attract more people who are able to help.
It’s also a good idea to keep your manuals in a safe place. Everything you need to know is explained in there.
