Midrange heavy speaker cables, any recommendations?

Thanks for all the feedback, guys. In response to the issues you've raised; my current loudspeakers are Quad L22 towers and a Mirage BPS150i sub. And yes, the Quads are more transparent and more revealing than the Dynaudios were. Overall, they blend well quite with my system. I'm not looking for a dramatic suppression of the top end, just a slight decrease in output. I have over a 1000 hours on the Quads.

I'm currently using Wireworld Oasis 8 cables which replaced the Morrow bi-wires I ran for 500 hours. The Morrows' were a bit more open and transparent, but I found the to be overly revealing high frequency-wise somewhat at the expense of midrange presence.

My initial thought before I posted this query was that my next step was either Cardas or MIT cables. Having used both brands before my thoughts were that both brands would bring me closer to the midrange bloom and top end attenuation I was looking for.

I will consider all the options you have provided me and I thank you for your valued opinions. Other perspectives and opinions are more than welcome.

Except for convenience why terminate speaker wire?  Aren't you just adding two additional connections into the stream?

If your constantly swapping wire I can see it but for me speaker wire is set it and forget it. Do terminal ends improve sound quality? 

@danager I completely agree.  The best speaker wire termination is no termination.
