VDH cumulus 3T speaker cables

Hi, I currently use Burmester Blu speaker cables. My system comprises Burmester mono amps driving Rockport Aviors. I am looking for a cable upgrade without breaking the bank! I have been contemplating either the Van Den Hul cumulus 3T or the Tellurium Q Silver Diamond.

i will really appreciate some insight and feedback on these cables. While the Tellurium is well reviewed, the VDH has very sparse reviews. Where I am based, I cannot try different cables before buying unfortunately. So user insights on system compatibility etc will be very helpful indeed.

As to the other cables in he system, I am using a combination of Acrolink power cords and Burmester silver interconnects.

thanks
