AKSA 55 power supply options?

Greetings all,

I have been using AKSA 55 with a lab power supply, but I now intend to build the AKSA as a pair of mono-blocks, perhaps eventually being built into a speaker enclosure.

I was wondering whether I should use linear powers supplies, i.e., rectifier, transformer, capacitor filters, or, given the advances in switched power supplies - efficiency - use these?

Any recommendation both regarding the different concepts, as well as specific parts would be appreciated.

Kindest regards,

M
