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.

Much Thanks! Bo and Zd.

what does one gain between the different V factors?
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.
