Have you auditioned both and arrived at these two brands as your final choice? Of the two at your price point I would choose AQ. If you have not auditioned, add WyWires Platinum. I preferred them over similarly priced AQ. Very neutral, spacious and detailed SQ without being cool and analytical (like how I find Nordost). Personal preference. Read pro reviews and add to your audition list. The designer, Alex, is a pleasure to work with.
