Wireworld Silver or Gold Eclipse 8 - IC or Speaker Cable?

About 20 years ago, I owned some costly Wireworld interconnects, probably the Gold range. I then deviated from WW and tried other brands. Several years ago I tried the Electra 7 PC. Fast forward to today, I recently tried the Silver Electra 7 PC and Platinum Starlight 8 USB. I’ve only installed the Silver Electra 7 power cord and so far things are looking promising.

For people who say that Wireworld PCs are the weakest product in comparison to their interconnects and speaker cables, I partly agree. I find that the power cords don’t sound good when used on amplifiers, sounding dull and flat with reduced dynamics. I solely use the PCs on digital sources such as DACs and they perform well here.

Coming back to the question, I may be interested to try the higher range Wireworld interconnects (balanced XLR) or speaker cable in the near or distant future when I get the itch. Currently I have pretty good and costly cables in my system but am curious about the Silver and Gold Eclipse 8 range. Questions as follows.

1. What is the main difference in sound quality between the Silver Eclipse 8 and Gold Eclipse 8? Which is more dynamic, smoother, detailed and 3-dimensional?

2. Generally, which is considered to be better with Wireworld products, the interconnects or speaker cable? In other words, a cable that is capable of bringing a larger impact or improvement to the sound of the system.

Before anyone asks, the Platinum is left out as it is a little too rich for my blood. However, I wouldn't mind people posting their impressions on the Platinum vs Gold vs Silver Eclipse 8 if the comparison was made.
