Default SMPS with split rail output for Class D?

If an SMPS was being designed to supply a Class D amplifier……..would it make no sense to have a split rail output, since an SMPS can be designed to have a high voltage output without resorting to split rails (unlike a 50hz mains transformer)?

It would depend on the amplifier that is intended to work with the SMPS being designed. Some Class D amps run off split rails (e.g. UcD), some use single rail (e.g. TI's PurePath).

BTW, it would make sense to ask all your questions in a single thread, not in three separate thread. That way, you'd get more coherent response.
