I concur with this thought.  I've known several techs who would put in
better opamps, bigger caps, etc in the analog output chain, and beef up the
power supply.  In a couple of particular products, they'd add some ferrites
and what not, trying to get the digital clock hash out of the analog chain.
It's probably more work diagnosing why it's got problems than figuring out a
fix.
