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.

Thanks, Mesch. I look forward to reading your impressions. I have different speakers now and I may demo the Columbias again. They are smooth and lively and might work better with the speakers I a using now.
Received and placed the Columbia cables into my system. I did not care to A-B then against the KCs, simply replaced and sold them. The result seems to be better imaging within soundstage and more 'air' around upper midrange/treble notes. I am happy. This represents the last piece to be exchanged in my system which took 3+ years to put together. Thanks all!
They are better in every single part compared to the KC's. Time for them to improve there cables.....
Thanks for the update, Mesch. It's great when a system comes together. Enjoy!
