Harsh cable audio solution?

I have my TV stereo output routed through my 2 channel tubed preamp and Sonographe amp. The sound on most cable stations (regular analog basic cable) is terribly harsh, hashy, sibilant and distorted in the treble. Seems to be somewhat channel dependent - the audio quality of each channel seems to be hit or miss, levels and mix and distortion seems to be all over the place. Ie, most of the disortion seems beyond my control if its at the station engineering level. But maybe there is something that is system dependent on my end?

Anyone experience this problem or know of a solution? Maybe sheilding/filtering at the cable level? Have a low end Monster power sheild/strip - haven't used for the cable routing as of yet.

Are their "high end" sheilded coax jumpers? (need about 4-5 feet).

I have to agree with Elevick. I have Comcast digital cable with the Motorola HD box (digital coax hookup into a Sherwood 5.1 Surround receiver) and the sound quality is very good.

On the channels that broadcast in 5.1 surround, the HD picture is better quality than a standard DVD and the sound is every bit as good in every way. On other channels the sound quality is still very good and totally acceptable. Some channels sound slightly better than others, but I haven't found any that sound bad in the ways that you've described.
