Is a high priced Line Conditioner needed

A power conditioner is not mandatory for good sound.

Unless, of course, you sell them.

I installed three dedicated lines with hot, neutral and ground for each dedicated line. My noise floor dropped dramatically, the sound is wonderful. low level electronics were originally all connected to Monster HTPS 7000 signature conditioner. Each amp had their own dedicated line. The I bought a Transparent audio Power isolator 8 conditioner which replaced the Monster and a noticeable improvement in the sound. Also, my house is the first house off the transformer and my house voltage is very stable. But, the Transparent definitely made a noticeable difference. I am a strong believer in connecting all low level electronics to the same outlet strip or power conditioner into a dedicated line, and the amps to their own dedicated line. You eliminate ground loops and the noise is significantly reduced.

Why waste money on a High priced Conditioner for a dedicated line?

Exactly

Precisely Minor1.

those Monster conditioner products steal the current from your system, more to the point, power amps.
