Hi BlueRanger,
Based on my personal experience, I would vote for the Purist Audio Venustas; if you wish to spend that much money. My second choice would be the Silver Audio - Silver Breeze (which I now have for sale here after upgrading to the Venustas). The Silver Breeze is very detailed and accurate. You will notice much inner detail that you have been missing, and more dynamics in both the treble and bass. You will also notice greater interplay in the harmonics of the music. It will seem more musical. Compared to the Silver Breeze, the Venustas seems to have a "darker background" - lower noise floor from which the music emerges, while every other quality is similar to the Silver Breeze.
I have not heard better cables than these two.
I believe that the Hovland and Ayre cables are better than the Ic-70, but have not heard them.
I presume that you are looking for a DIN to RCA connection. There are generaly several cables configured that way for sale on Audiogon at any time.
Best of Luck,
DuffyDawg
