you didn't mention which ic's from sr and kimber you were thinking of. I only have experience from the higher end sr cables from years ago, and they excelled in inner detail and staging qualities, they conveyed all of the 'warm' very well, but were also what I would call neutral. they definitly did not add glare or hash. While it is true that cables from certain manufacteres often share a family resemblance, sr used to offer a free service were you tell them your system and they would recommend which of their line they would recommend.
The kimber lines I have found all have a tendancy to convey the detail in the upper end the very well and would tend to sound bright if the source was. While they are difinetly capable of great bass and harmonics and detail throughout the range, the copper can sound hashy at the top as well as a little nasally in the mids (the price for extreme detail I would say) and the silver, while beiig very smooth, will lean toward the bright.
however, I would be cautious spending too much on ic's for the tuner. I listen to a lot of radio lately, and what you desrcibe as distracting voices sounds like am I presume? That is simply the broadcast and the more fidelity you get from am, the more distracting it will become perhaps. (sansui's have a rep for good am I understand). Sansui's also have a rep for being very open sounding with good staging qualities, but in addition what you descibe as far as bass and 'chesty' is also what a lot of radio stations sound like. The more fidelity you get from your tuner the more 'odd' the broadcast may sound to you, as many stations compress and alter the sound of the broadcast. I would advise to use the fidelity of your system (and cables) to judge the sound of the radio and steer away from using your tuner to judge the sound of your system. I would use whatever cables you have as 'leftoners' and/or buy whatever cables you think you will like for the rest of your system before you buy cables for your tuners particular qualities, as you will more likely find the sounds and qualities of different tuners will vary more than trying to alleviate with cables.
