Will a Power Conditioner Help?


I am setting up a new home theatre system and need some advice. When I was remodeling my apartment I ran a heavy power line under the hardwood and put an outlet in the floor (don't ask - my TV works as a room divider), and have been using this outlet for: TV, DVD player, computer, and the A/V receiver. This may seem like a lot, but now I think I may be having a real problem - I decided to go to separates, so will have a pre/pro and a 200W*7 amp instead of the receiver. Something makes me think that one power outlet to run all these devices is not enough. Will a power conditioner help? Thanks!

the big furman units ref 15 or 20IT are great for all --least expensive for front end stuff is powervar
Alrau1, thanks for adding details about mode of operation of the LC-1800. What I like about it (and many similar units) is the noise rejection by means of a toroidal transformer. It works wonders for digital!
You'll also notice that I specifically said to NOT connect a power amplifier through this gadget. It does limit current which is an issue with high power units.
I guess I don't encounter large voltage fluctuations, so I haven't noticed erratic behavior. Like I said, there are other units and i'm sure that some of these do not switch taps but just filter the noise through a magnetic circuit. These are much more effective than some pathetic implementations with lots of LEDs and a digital display on the front panel...
Serus,

Just one correction: unless Tripplite redesigned the LC-1800 since I bought mine over 10 years ago, the tranny is NOT toroidal. It is a true transformer, with separate primary and secondary windings, though, not an autoformer (a single winding and no isolation).
Stupid question. I understand why an amp shouldn't be plugged into line conditioner, but how do you protect it from storms. Don't say unplug, I'm not home 24/7. Thanks.
