@ghdprentice is correct. do the lending lib rary at thecablecompany.com the best way to go. I upgraded once from a set of AQ Yukons to AQ Water, it was a good step up, but I was not in love with them. Have since moved from AQ back to Nordost. I would say get a set of Water and a set of Nordost Heimdall 2's they are both in the same price range. it should be great fun. Moved my entire system to Nordost Heimdall 2.
