Is a high priced Line Conditioner needed


I have 2 dedicated power lines coming in to my wall for my stereo.Do I need a high priced Line Conditioner to make my system sound better and or safe or will a small priced Monster do the trick?Why waste money on a High priced Conditioner for a dedicated line?Thanks for your help!

I use PS Audio PPP for tuner, CDP and preamp but not for amplifiers. I find it to be a good thing.
Rsa,

1st stay away from Monster products (so-called conditioners).

2nd consider some kind of line conditioning if you live 'on the grid' as in one of our major U.S. cities.

Let me know the other gear in your system and I will point you in a direction to get started!
I am quite happy with my Shunyata Alpha 4. Can you something to demo in home? Let you ears tell you.

Plato 9-20-13 said it best.Go with an Environmental Potentials 2050 and 2750 at the panel to begin with,first things first.Then acoustic treatments for the room.
A power conditioner is not mandatory for good sound.

Unless, of course, you sell them.
