Daniel at the NY meet one of the headfi members put a balanced HD800 into the WA5 XLR jack and man was I surprised . The HD800 jumped up another notch. I was afraid to try it with mine but after listening I will use the balance doable and even Jack Wu was surprised how good it sounded. The HD800 scale higher. LOL
I should of done that w/ mine it has a balanced cable :/
I never had tried it until the NY meet but it suorised me and Jack Wu as well . It really sounded excellent.. I am waiting for a nee moon balanced cable to play with it. i do have a Norse cable that I will use this weekend balanced.
