dedicated electrical line

So, if you cannot install a dedicated line, is the next best thing a power conditioner?

It is supposed to filter out all of the noise from appliances - isn't it?

I know power re-generation is probably the ultimate alternative, but it's BIG$$$

What are the drawbacks of conditioners?

Thanks

From Rf_gumby: I've only heard a few times that conditioners made the sound better

When I added my power conditioner to my AV setup I noticed an amazing difference to the picture quality and the bass tightend up considerably

When I added one to my hi-fi I noticed much better all around sound - but - I'm still not sure if it is the effect of the conditioning - or the fact that the outlets on the conditioner make a much tighter contact with the plug than than what I had previously been using

I did compare:
1. the amp plugged into the conditioner as opposed to
2. the amp plugged into the wall outlet

and could not detect any audible difference - in both cases Furutech power cable was used

The biggest difference I have found is replacing the wall outlet with hospital/Lab Grade outlets
