You have spent a lot of money exactly..
Does it also make sense to choke the system with the following choice web jockey type cables in your system?
YOUR PRICE: $399.00/ Pair
Easy Pay: 3 payments of $133.00

85 k system with a pr of 399 speaker cables WTF ?
As I told you before if you put a double shotgun Bi wire of AQ Meteor w/ DBS you will have not only have height but hear how good the ARC/Vandersteen combo is.

Audioconnection,
That's an interesting observation and implies you're familiar with this system.If better quality cables resolve this problem it's certainly cheaper than replacing the speakers. Or perhaps the OP just simply wants new speakers.

The OP has been very clear, he wants big sound.

Well it seems according to JohnnyR big sound is possible with his suggested speaker cables.

Furthermore OP has absorption everywhere front wall,side walls and absorption at rear walls behind listening chair.

It should be Diffusion at least w/side walls for best performance or nothing is even better that absorption.

Test by removing all absorption front side and back remove out of the room insert AQ DBW and listen,and see how you like it.
Replacing absorption with diffusion will get the joy and magic back in the system.
With too much Absorption we are killing the music's leading edge attack,overtones,harmonics even/perception on Height.
This is why OP also found that band aiding the system with a ringy wire kinda helped.
Try the experiment of Absorption removal and In-cert AQ
add Diffusion
