I am using AQ KE-4 and Diamond Extreme, which are supposed to be very similar metals to Everest and Amazon.. They are very fast and detailed. I had some of the Nordost SPM reference, and whatever their megabuck cable is (valhalla?) and they were also nice. I chose the AQ because the price was so much better since I found AQ cables used. Nordost was very nice if you have the $$
