I can see where you're coming from.
The Monster unit also has a 15A power rating as well.
As far as the Isolated filters on each bank, I can only say that it's a good/bad thing.
From my experience in dealing with EMI/RFI interference in power lines, I've had to dissect several devices to inspect their workings before my company made a purchase.
What a power filter does (at the AC level), is it creates an "impedance mismatch" at high frequencies causing incoming unwanted frequencies to be reflected back to the AC power network. Likewise if the equipment itself is generating noise (Receiver, Amp) some filters are designed to create high impedance to the equipment and so control outgoing interference. So knowing the input impedance of the equipment is very important to what type of filter should be placed on that specific circuit.
That is why I suggested the Monster unit again over the Tripp Lite, because it uses special application filters which would more closely match the impedance of the device it's powering.
I didn't know you could get the Tripp Lite for so cheap though, so there is a $100 price difference. I guess in the end, just go with what your instinct tells you
