Default Best Sounding Power Supply for D-class amp

Hey there,

I just ordered an Class-D AMP6, and I was wondering what type of power supply sounds best?

- SMPS
- Conventional (Transformer, rectifier, caps) - unstabilized
- Conventional (Transformer, rectifier, caps) - stabilized


Thanks, Tom

What's your application?

SMPS = lighter weight.

Any power supply if well designed it would have no negative effect on the sound.

Not sure what u mean by application: It's a small system in a bedroom, two mini-monitors (Seas based), digital source, and the AMP.

Was wondering if someone has compared different types of PSU, that are readily available to / easily built by a DIYer.

I understand that if done right/perfect/ideal, there is no difference.

thanks, Thomas

I am seriously considering buying the amp6 myself and have contemplated the same question..
I will be interested to hear from anybody who has built one. Are they happy with the onboard smps and which transformer is considered best?

I found a Mean Well SMPS (SP-145), looksok so far. Does anyone know if 100 mV p-p ripple is acceptable for audio?

Thanks, Tom

Did you get the AMP6 Basic? Because if you got the regular AMP6, it has a power supply onnoard. Just supply AC. Works great. It's a simple regulated linear supply.

You sould use something similar for the Basic, or a good SMPS. Extra filtering always seems to help.
