It really depends on your mains condition and the load.

My current home has very good wiring and little need for that. So I don't use one right now.

In the past I have used a 1000VA transformer to isolate my gear from the mains. But that size was based the size of the highest current draw I anticipated at that time. You would need to calculate the size that would work for you if need it.

Well a 250W unit should be adequate and a 500-1000W unit would be even better.

You could go totally ott and use the same as me - 5Kva... bit big and heavy mind.
No I'm not joking either - it sits outside my office humming nicely to create silence inside from any traffos used after it.

Just finished my Buffalo III Legato this afternoon. Not near broken in yet and this DAC sounds amazing. The soundstage is huge and images in precise locations. I have never put something together and had it sound this good right off the bat, I can't wait till it breaks in.

Thanks Russ, Brian, and LeonvB

Can you show a schematic how to connect such stuff? The benefit will be no hum (not mechanical one) from traffos in afterwards circuits?

That would be better for a different thread. You actually might get more info on the power supplies forum.

Cheers!
