APC on Sale

Well, I couldn't think of where else to post this since there is no "Other" category under Audio Hardware (hint) and I want to stay away from General Rants n Raves

Anyway, came across this -

Seems like very attractive pricing. What do you all think of the H10 and H15 products? Good buy at these prices?

Re: APC on Sale

Those are good prices but APC products use metal oxide varistors (or MOVs as they are more commonly known) which do not react as quickly as Avalanche Diodes. Below is a some stuff that I wrote comparing Monster to Panamax. Since the comparison was really MOV vs. Avalanche Diode substitute APC for Monster and everything will still be relevant and accurate.

Monster power conditioners use MOVs, which have a relatively limited lifespan. After the MOVs are gone MANY times the units continue to pass current to the equipment meaning that the next surge could destroy the connected gear. The Monster units do have a light to indicate that they are no longer protecting the equipment but who wants to depend on a light that they can forget to check?

Panamax uses an avalanche diode that acts almost like a flood gate. It opens when voltage is above or below a safe area, then starts testing the voltage. After the voltage is back within the normal range for 7 seconds Panamax units allow the equipment to receive electricity again. When an avalanche diodes fails they are stuck in the "open" position 99.9% of the time. Meaning that the equipment receives NO electricity so the user knows that the power conditioner needs to be replaced.

Panamax specifies that MOVs are 1000 times slower then their avalanche diodes. At trainings Panamax regularly does a demonstration where they hook up a Panamax and a Monster into a device that can create spikes, then into each unit they plug an illuminated lamp. Both units are then hit with a 150 volt spike. In the 10 or so demos that I
