New silversmith fidelium cable

Or in the case of this website, a link.... (if possible)

Scratch built amps, no websites.

Post to post the binding post are 7/8" apart. Then I have my RCA input about 1 1/8" to the left of the binding posts. On the other side I have a grounding post and the gap there is about 1 1/4". No obstruction above or below.

Are these two mono Amps you're talking about?
If so, I think there's plenty of room to hook up the Fidelium Cables.
They are bendable across their 2" dimension.

The silversmith fidelium cable is 33% more conductive than any copper or silver foil out there.
