1) Depends on the app. Voltage drop etc. But it is designed to do 1.5A or so under the right conditions. Its just a prototype right now, so we still need to test the limits, but that is what it is designed to do provided adequate heat sinking etc.

2) About ~200ma each rail idle. You will want to add to that your anticipated headphone (with 2VRMS) load to get your CCS cuurent plus say 25% headroom. I would say 300-400ma from CCS would be a pretty good place to start.

That is yet to be determined.

Yes quite likely, but Placid is actually a different circuit then Placid BP and really more suited for high current than PlacidBP.

Legato 3 - Look ma! No caps!
Russ and Brian,
Do I understand correctly that when using the L3 with balanced output only the circuit is identical to that of L2 (except for the missing caps and different fets)?
Cheers,
Nic

Yes, essentially identical.

I mean...with a PlacidBP is possible to obtain +-12V and 300 mA...isn't it? Is that sufficient?

Maybe you want to supply anything different than a Legato or a BII.

Nothing to explain, just that if you want to supply a different diy device that needs higher currents, like a preamp, or even a little poweramp, you can do so.
