Neutral Sounding Silver Cables?

In my experience, Ridge Street Audio Poiema 3s fit that bill very nicely.

There are no neutral cables.
Try some better Purist Audio cables too. I would also try DiMarzio M-path cables, $150 or so for a 1.0 M pair new. They may not have silver in them but they are very balanced. In direct comparizon in my SS system they were very close to Purist Maximus which cost $800 new, and highs were perhaps even a little better. Not bright at all, excellent bass. Great value.

I had used a number of cables between my BAT VK-D5 and pre, before settling on the Kimber KS-1130's(about 6 years ago). They simply let everything through(freq extension-both directions, without bloat, becoming sibilant or grainy/great sound stage-WxDxH/Precise imaging/ambience information/instrumental tonality and decay, etc). Every change, that I have made downstream, has just allowed more music to flow, from the CDP and Kimbers. Ditto, with the Kimber KS-1030's, at the output of my phono pre. If a system sounds overly bright with them connected, they are simply passing an overly bright signal, from elsewhere. That is the nature of any cable that is more neutral(passes more information/signal, without editing) than another.

I would second the Acoustic Zen Absolute.

I should have mentioned: Do yourself a favor and contact The Cable Company, to audition a pair of Kimber KS-1130's(or whatever else suits you) for yourself, via their Lending Library. There's a small fee, that will be applied to whatever you might purchase from them(new or used). Good people to work with! (http://www.thecableco.com/Catalog/Interconnects)
