The Cat II rating should be fine for your purposes. I wouldn't like to use it for mains where there's a lot more energy available. The amplifier HT may be able to give a few amps in the event of a short circuit but it's not the 10s or 100s of amps you can easily get from the mains. The hazards in lower quality DMMs are usually about what the PC tracks and fuses will do in the event of a high current surge. With arc flash as the really nasty consequence when you have 100s or 1000s of amps available. You won't get arc flash downsteam of an ordinary ring circuit 32A fuse/MCB.
While you're obviously going to keep your hands clear of the 4mm plugs (unshrouded with a cross hole) I'd do an insulation test on that switch toggle which you will be touching. 500V DC minimum, 1000V is better.
