Dedicated lines IMO do not impose greater quieting, than do power cond/filter.... with or without dedicated power lines. Dedicated power lines are good ideas, and they do improve things. Dedicated power cond/filters just do more to allow a system to achieve a higher level of performance. Albeit, som will say otherwise.
IMO, the one aspect of power conditioning I feel is always accurate is this... "With a power cond in place, you will hear less of what you are not hearing now." it's simple increase by subtraction.
If it in fact improves the sound itself too, then you are doubly blessed. For me, they took/take off the edgyness and gave greater apparent resolution from providing a darker back drop to the sound stage and thereby illuminating the images within it.
Can there be limitations? Sure. Limitations to the bandwidth being served, and current being passed. Noticeing these diffs is easy too... just plug right into the wall now and then when demoing conds or filters. this action is what recently prompted me to find a more free flowing power conditioner to replace the one I was using for my power train. I settled on trying a RSA haley. that was a good move IMO and I posted a short review of it here on the 'gone.
I find plugging directly to the power line allows greater dynamic thrust, speed and impact versus going through a conditioner. I don't care for the edge to the highs and mids which accompany that move. So a power cond/filter for me is a given. Which one however remains an ongoing pursuit, though right now things are quite acceptable.
