Most SMPS’s that can be strapped for either 120V or 240V run a full wave bridge in 240V mode, and run a DOUBLER in 120V mode. That doubler is MUCH harder on the rectifier and caps than the full wave. Peak currents are lower and the power factor is better - the ripple current in the caps goes from 60 Hz to 120 with a lower RMS. Cap life increases. You can often put out more continuous power, safer, when strapped for 240. If it’s an unregulated converter, the regulation will improve making the amp put out more power, too.
What may not be so clear is what you can do loading-wise on the 240V/30A circuit, by code. Most 240V circuits are intended to feed ONE device off a dedicated outlet. I’m not sure if code will let you get away with multiple say 10 amp loads off a 30A/240V circuit. I never see it done anywhere - even in commercial settings. In my distro, each outlet has its own breaker. The big circuits (including the 30A/120V) feed ONE amp. Only the (split-wired) 120V are duplexes - but most kitchen outlets do that.

Thanks for the info, that agrees with what I have found from a variety of sources.
As for the number of devices/outlets, I would indeed have just one: a single powercon in an outlet box feeding one six channel amp.
Again, thanks.
