Cable recommendation for Krell & Vandersteen

I have some Studio Cables 4S Interconnects and Bi-wire Speakers cables for my Vandy's

I also have some Studio Cables 4S cables for my 2CE's. Check them out:

I've been happy with Anticables (bi-wired) and Anticables ICs for my 2Cs using both Krell and Vincent amps

Currently using mogami 3082 for speaker cable and mogami 2534 for balanced connection between krell components. Sound is good, but seems maybe slightly veiled and slightly boomy in the mid bass. This of course fluctuates a little depending on what type of music you are listening to, and quality and mix of the recording. Not sure if I should be looking at all copper stuff, all silver or a silver coated copper? Since posting this query, I had emailed The Cable Company for some input. Based ob my budget of $500 or less, they recommended Kimber Hero XLR and Kimber 4VS/8VS. I assume they mean 4VS for the upper and 8VS for lower on the Vandys. The didn’t recommend AQ as they are warmer sounding. Another thing to mention (and I’m sure this will generate some responses) is that I’m using the Vandys in single cable mode, no biwire. I have tried biwire in the past and I feel there is something missing in the range of sound. Almost like there is a gap somewhere. However, this was a long time ago, and perhaps I should give biwire another try. I do have a hefty supply of MIT in-wall speaker cable I could use to see of bi-wiring does anything for me. As for Kimber, i used to have 4TC at one time and though it was a very open and full sounding cable that didn’t enhance bass, but rather kept it punchy. Of course, I cannot recall what gear I was using at the time, but I still had the Vandys at that time. I just wish I could try cables out before buying anything since there are so many factors involved.
