Acceptable Aleph Ripple?

[dshortt9]

What is acceptable ripple in a power supply for an Aleph ( 2 ) assuming medium sensitivity speakers? I do appreciate quiet electronics and a "black" background.

Without a pi filter or a regulator, you'll see about a volt
or so. Use a pi filter and get it down to millivolts, and you'll
be happy.
