Value of upgrading only 1 set of interconnects?

Thanks for the feedback, reinforces most of what I was thinking. 

Current have Cardas Sky for speaker and interconnects. 

Room is already treated. I already address dedicated power line and  regenerator

I have HF Reveal and Cerious Matrix PCs for main power and DAC, Pangea 14SE MKII for Pre. Each of these updates brought goodness, just chasing more of the same

Once the new cabinet is built I'll update PCs to the amp. I'll be able to go with 1M cables then. 

Lots of good feedback, Thanks to everyone

I really don't want to get into details about what I expect the cable to bring as those seem to derail into snake oil deals. Just went through that on another thread, interesting when I shared some measured changes it was still a love hate deal or just silence. Life is too short 

I will share that I got some huge improvements doing some PC upgrades and I want to hear more of the same sorts of improvements. If the interconnect doesn't do that for me its back in the box or I'll resell which ever doesn't float my boat 

BTW did try and reverse cable direction. Dead silence. Awesome quietest cable I've ever heard! Then again the XLR connectors don't fit so it just lays there being all quiet
