New silversmith fidelium cable

Looking at the pictures on web page I would think these cables would be a complete pain-in-the-rear when trying to attach them to binding posts.

I doubt I’ll get them to fit the binding posts on my amps given how close the binding posts are to one another and how close they are to the input.

Pauly,

I think the majority of Amps can accommodate this cable with a little effort.
They do have adaptors for those hard to fit Amp outputs.
Why don't you post a picture of your Amp's outputs to get our suggestions.

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.
