It is common to build regulated power supplies for 120 volts that work well
when the power line is 90 or 100 volts. For example a power transformer for
a power supply that puts out 12 volts might be based on a 16 or 18 volt
transformer. The voltage regulator will take up the slack most of the
time.

When modders get in and change the internal circuitry about, say trying
upgraded opamps, then the power supply is the next natural target for
the upgrade.

You mean downgrade of course !


The following document, for my dac-in-the-box is one approach of said
improvements (I've not tried this - I'm happy as the item is) where the
proposer has also had to upgrade the voltage regulators and then find a
better PSU. And suffer more regulator heat dissipation.

They don't call it AUDIOASYLUM for nothing. I hope your straitjacket is a good
fit.

MORON !
