Switchmode supplies have a bad reputation in DIY audio for various reasons. One reason being people being stubborn and reluctant to change. But there are good technical reasons why one wouldn't use a switchmode supply in an audio amp. But that's not saying that you cannot use one.

If you can find a switchmode supply that can deliver the needed voltage and current, you're in business. If not, then I recommend that you start with a transformer, diode bridge, and reservoir caps like everybody else...

I do *not* recommend that you try to design or build the switchmode power supply yourself.
