Dunlavy SC-VI

I use the SigTech (and have a Tact) on VI's. SigTech is better and Tact cost less. If you can afford the best (which, given your speaker choice appears you can) go for the SigTech.

I use Dunlavy cables

I still own the SC-V's as well as SC-VI's. I don't currently use any name-brand room correction aids. If you read through the Dunlavy Owners Manual or go to the "listening room" link at the Dunlavy site, John has some very good recommendations. You obviously like his speaker design, so why not try some of his suggestions for room treatments.

As far as cables go, you probably need to provide more info on your total system(including your room dimensions) if you want informed feedback. I myself use Dunlavy cables. I have discussed this choice with other Dunlavy owners, and we agree that the Dunlavy cables seem to work well with Dunlavy speakers, regardless of the electronics.
Hope this helps and happy listening.

I agree with Listener's response. John Dunlavy gives some great suggestions on room treatments. I followed them with excellent results. I also own both the Dunlavy Vs and the VIs. Best hifi purchases I ever made. After the speakers were drop shipped, I tried several speaker cables but could not audition Dunlavy cables. (I have no Dunlavy dealer in my area. I hear they are outstanding though.) After many trials, I chose Nordost SPM. I highly recommend them. Smooth, silky, great detail.
