Hi Tholt
I have my SCs and PCs in my system elevated either with Myrtlewood blocks that raise the cords approx 3 inches above the ground or I've just tied the cords in such a fashion that they are off the ground entirely by more than a ft. It is an ugly mess but they are off the ground. Now I never had any loss in bass response but then my system is not as nice as yours.
FWIW I did lose some bass boomminess when I changed out my subwoofer isolation platform. I have a Velodyne subwoofer that is facing downwards and I was using an Auralex SubDude that raised my subwoofer 2.5" from the ground. I changed it out for limestone tiles that now have the sub raised 4.5"-5" above the ground.
Good luck in tracking down the issue.
