Rick,
the E3610A is really clean.
If that isn't good enough, there are some audio-related circuits like
the ALWSR.
http://www.andrewweekes.talktalk.net/Manuals/ALWSR_rev2.9_Iss005s.pdf
It's based on a Walt Jung design (Analog Devices).
Here's the man himself with tons of valuable information about ultra low
PS design:

I know this topic has been discussed in the past on the list, but
a colleague is asking if there are any off the shelf low
noise power supplies for testing oscillators. Something
a cut above an HP "brick" lab power supply etc. They are hoping
to avoid having to homebrew a power conditioning circuit.
Did we ever arrive at a concensus as to the state of the art
in homebrew power conditioning circuits?
Any help would be appreciated.
