Upgrade from AQ King Cobra to Columbia DBS


I'm currently connecting my Jolida Fusion Pre to my BEL 1001 MK5 using AQ King Cobra, 2M. Would it be worth while to upgrade to AQ columbia with DBS, buying used? Thanks in advance for opinions.

Want to thank Bo and Zd as I bought my first pair of Columbia. Looking for another.
Always nice to know that there are people happy with my thoughts. Some people don't like me because they think that I bash there beloved audio stuff. Being critical is something else than bashing. I am also critical to the stuff I own myself.
Don't be so hard on yourself Bo. I don't know anyone that doesn't like your thoughts. Maybe your words, but definitely not your thoughts! It is that simple!!

"what does one gain between the different V factors?"

A headache. Just enjoy the cables and don't worry about it.
Bought my second pair of Columbia. Run .5 m pair between DAC and Pre, and 1M pair from Pre to Amp. Thanks Bo and Zd.
@Mesch, could you talk a bit about how the Columbia improved you music over the KC. I demoed a new pair of Columbia a couple of weeks ago. I had it my system for 7 days so it had settled in and I got a decent handle on its sound. I did like it. It was detailed, quiet dynamic and smooth. In my system I need a bit more fullness/weight in the mids.

I'm trying to figure out if I should try the Yukon just below the Columbia and save some cash or try the Colorados. Thanks for any thoughts.
