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

Consult an electrician to get advice based on the codes in your area. I can't figure out what you're trying to do. Figure out if you want 240v amplifiers or 120v first.

No change of the amp is needed
Depends on the amplifier.

Clarification 
perhaps my prior post was a bit inartfully stated

i am trying to accommodate future potential needs while addressing present and future costs.  I have no issues changing out breakers and plugs in the future to accommodate a potential 240 v amp., as last ng as the wiring and ground are adequate Definitely doing a new panel as I am adding 2 Tesla supercharger circuits, summer kitchen etc
