I found the best results from putting Machina Dynamica small gem bottles on the cable inputs, with the other three sized bottles (M,L,XL) one each on top of three Mpingo Disks in a forward triangle. They're both resonance control devices but do extra special together, but very sensitive on placement: best tweak I found. Haven't tried the Resonators. The Machina guy says the gems do better in a small plastic baggie instead of bottle, but haven't tried that either.
