Thanks for all the responses. It's good to have a wealth of knowledge to draw upon but let me clarify this, I'm not doing this in an effort to save money. I want to hear what titanium, molybdenum, and niobium offer as speaker cables. As slugs, the titanium and moly destroyed the copper in every way important to me. I also have solid silver slugs, which are very good and also leagues better than the copper. However, I find the titanium to be quite obviously more detailed than the silver and the images are so clearly delineated, it makes the other metals seem somewhat indistinct. Titanium tracks sounds better as well, moving across the soundfield. Pink Floyd tracks are a joy to listen to with titanium. And the moly sounds like the best of silver but smoother and sweeter. As far as I know, no one is making cables with these metals. A few have used tungsten, and the reviews are generally quite favorable. I read that the niobium resistors are top notch so why not experiment with the wire and see where it goes?
So, I'm not interested in copper wire, either Home Depot or the best Furutech/Neotech have to offer, which I'm sure sound incredible. I really want to hear what these other metals offer as speaker cables and even though the convenience of spades/bananas are undeniable, I feel they would likely compromise the sound. How could they improve the sound? Less is more! I just want to make sure I didn't wire the system up in a way that could cause probelems
