Looking to Develop A Short List For An Interconnect

I have two amplifiers here, they sound a bit different. Pre-amplifier is a Trinnov Amethyst. 

First amp is a Matrix Audio MA-1 and its quite interesting. Reminds me a lot of my Classe Omega I have owned. A bit lean in the mids and a bit vibrant in the top end. I enjoy listening to them, my JBL 4367 sound like electrostats. But the mid band is lean. I use a pair of Wireworld Silver Eclipse 10 XLR interconnects between amp and pre.  Problem is I do not own this amp. 

The second amp is a Constellation Audio Inspiration 1.0, which I have recently acquired. This is supposed to be my long term amplifier, so the one I need to work with. I find it quite a bit darker and richer than the Matrix amplifier. From what I had read of the Constellation amplifier, this rich tube like presentation is not expected. So far the best sound I have gotten with it is with a pair of Wireworld Gold Eclipse 8 I have. 

So I am looking to develop a short list of interconnects to explore. I want something that is a degree or two more upfront and energetic than the Wireworld. Ideally I will go to the used market so that I can buy and sell if needed. But new is not out of the question. 

I have wondered about Nordost, maybe some of the upper level Kimber. But any suggestions or insights would be greatly appreciated.
