The Puritan does not limit current. This has been my actual experience with large SS, pure class A amps which are very high current designs.I have a 2 x 400watt (8ohms) power amplifier with all my digital front end plugged in, with no loss of dynamics.
It seems to me that both the hot (active) and neutral for each outlet are individually high pass shunt to ground of the electrical hash (noise) to ground. There is another ground connector on the chassis, which would offer a different potential for the bonded neutral, which is claimed to do more even again.
Yes the Puritan is a solid performer, and represents excellent and functional value for money. I’ve been told there are better, but from the same reports, do expect to pay at the very least triple the money. **With the exception perhaps of the Niagara for less than triple the dough. And of course there are always emerging products that we here are probably not even aware of.
