Monster HTS power conditioners, do they work?

Some of the less expensive Monster PLC's actually introduce noise into whatever is plugged into them. To avoid this problem, stick with the larger units that have at least eight outlets on them. Whether or not you can tell a difference in your system with any PLC hooked up is going to be system and location dependent. As to whether or not you like the results in your system if you can hear the difference will be a matter of personal preference. Sean

I agree they will improve the TV picture. While they do something, I do not think they do much for audio.
