Silver Speaker Cables

I am using Albedo GEO silver speaker cables and I'm very pleased

The Clear Day Double Shotgun mentioned above by @dill are the lowest priced silver speaker cables I remember ever hearing of ($500 for an 8 foot pair). They are no longer in production (the designer/builder died a few years back), and rarely come up for sale (they're good).

You can try Vogue Audio. I'm using their speaker and power cables and currently have 50% off speaker cable for this month of September. The speaker cable and all their products are 7n silver.

Thanks for all the feedback thus far! Appreciate your input.

Having used and experienced both I found that silver provided more detail and an improved soundstage.  They can, however, brighten your music a bit too much.  I am not sure of your amp and speaker combo but that also plays a big role.  Amps I demoed and heard were Boulder, Luxman, McIntosh with Martin Logan, Wilson, Focal among others.  I thought silver was too bright with Focals, but the best combo was Luxman and McIntosh with Martin Logan's. 

Good Luck and let us know how you make out.
