dannad,
+10% is customary and listed in my Benchmark AHB2, but M10 specification or back panel says nothing. They don't even mention frequency. I'm sure it works at 50Hz, but no specification available.
If we assume that NAD would be completely safe at 230V then I wouldn't bother with additional piece (transformer) and simply sell Panamax (<$300). In Switzerland I would get something similar or better for 230V (tight non-sacrificial protection). Transformer is a headache and might limit choices in future, not only by limiting total power available, but also because most of the gear sold in Switzerland will be 230V only. Such gear can be plugged directly into wall, but then what Panamax is for? Another protector/conditioner for 230V? Perhaps operation at 50% of max voltage is safer, but Switzerland is a very civilized country - they don't have lightning :)
