Inter Connects - What I know and don't know

I've been researching Balanced Cables in anticipation of adding a new pair of mono-blocks (Atma Sphere Class - D) to my system. I'm hoping some of you who know a thing or two about cables might help me (us) clarify or demystify certain assumptions.   

My assumptions:

- You get what you pay for ($300 Brand X will produce more detail than say $60 Mogami Gold).

- The larger the gauge the better.

- Crimped and soldered connectors are better than screw tightened.

- Two or more large braided strands are better than several smaller gauge braided strands (all things being equal).

- Silver conductors are better sounding and measuring than Copper conductors.  

- Rhodium, Gold, Silver, Copper, & Brass, connectors objectively sound different. (as opposed to in your system).  

Remember, the more objective your responses are the more helpful they'll be to a majority of readers. 

Thanks in advance for your "feedback"
