A bit over a decade ago I constructed a power amp based on an SDS-258 modules from Class D Audio. The kit I purchased included a linear power supply. Presently I'm contemplating replacing that PS with a switching-mode one. The current linear supply puts out +/- 62 VDC.
I would like advice on a proper SMPS to replace the linear.
Incidentally the SDS module is/was Class D Audio's audiophile offering whereas the CDC model testing by Amir is not considered by them to be a good.
My reasons for this swap are essentially two:

My reasons for this swap are essentially two:
- This amp is a backup amp for my main amp, (Purifi), and others so gets move around fairly often; it's excessively heavy thanks to the large transformer; hence I would like a much lighter SMPS supply,
- Secondly, more on principle more than practical consideration, I would like a efficient, less power-hungry supply
