120v vs 240v


Doing a electric panel upgrade and thinking of running 3 new dedicated 8 gauge circuits, 2 for possible future 240 v  ( which can also be 120v) monoblocks and a dedicated 20 amp for other gear
What are the pros and cons of 240v  vs 120 v for amplifiers

also how many isolated ground circuits do I need?

 Thanks

240 volts allows for smaller wire sizes since the amperage draw is cut in half for a given amplifier power consumption rating at 120V. Since you are using #8 wires you are negating the main advantage going to 240V.
