Advice on 24V power supply

Hello fellow enthusiasts,

In the past few months I've built an ACA amp and ACP+ pre-amplifier. Great fun, great sound! (Hooked up with Klipsch R-51M speakers.)

As a future project I'm thinking about building a solid, clean and stable power supply, able to drive both devices at once. I guess it should be able to deliver 150VA (or more?) with 24V output or similar given 230V AC input.

Please share your ideas what would fit. A kit is convenient, if applicable.

Regards,
Kees
