Switching or linear for pair of TPA3255-1CH-480W boards?

Looking at 3e Audio site and see these 1 channel 3255 modules now have op amp option, but as they stopped supplying their switching supply I'm looking for advice on supplies either linear or switching, also shd I keep as balanced monoblock or simple 1 case etc.
Guessing I need 36-48v and around 300 w per channel?
What's a reliable supply ?


Cheers Will
 
Thanks Jason.

S that 350 per channel? Will check
Atm thinking to hook this up with a matrix mini pro 3. Decided on a single box. Will probably use Muse 2 OP amps as they are neutral sounding and detailed, as Matrix has various filters
