Do power conditioners help with unwanted hum/noise

Thanks Sean, the iso transformer would be an easier upgrade. I used it on the CDP for the biggest improvement but always wondered how it compared to choke regulated p-s.

I had the same exact problem on my system. I was able to do it by simply puting a 2 prong to 3 prong adaptor onto all of my power cords. This eliminates the ground loop on your house's circuit and if that is the source of the hum (which it most likely is) it will cure it completely. I went from almost unbearable hum to quiet as a desert.

You want bang for the buck. Go to Home Depot and purchase a Belkin AV Master for $75...that right...$75. I am using one with my Naim CDX...only Power Conditioner that totally gets out of the way...lets the dynamics come through...along with the detail. I stumbled into this when I tried it with a Roted 965LE, with miraculous results...I was all set to go for the HYDRA. The Belkin offers amazing bang for the buck...I now own two of them...an amazing product providing you don't believe you have to pay $1,000 for this kind of result.
