Rsjm80, I use Furman Elite 20 PFi. PF stands for power factor correction -
in short big inductor and big capacitor. On one hand it appear as load
closer to resistive but on the other can provide high current to the load
(because of mentioned capacitor). Most of electronic components have
linear power supplies and take current from the mains in short spikes of
high amplitude. That is the main reason for many power conditioners to
cause loss of dynamics (big volatge drops).
Also most of inexpensive surge protectors use MOVs that have limited life.
My Furman usue non-sacrifitial protection that last practically forever. It
consists of 12 outlets - 4 for amplifier, 4 for video and 4 for audio-video.
All outputs have specific noise filters. Believe it or not but my HDTV has
better colors plugged into Furman. There are better Furmans and better
conditioners (I don't want to sound like advertising for Furman), but I want
to stress the point that good filtering and non-sacrificial surge protection
without loss of dynamics is possible.
In addition I installed myself whole house surge protection in form of dual
20A circuit breaker (Siemens style panel) that I bought in Home Depot to
replace existing one (5 minute job). The only difference in shape is
additional wire that, cut short, connects to ground bar.
