i would consider a WA5 if it actually drives the HE-6 better than gsx mk2. i've heard different opinions. some saying a speaker amp would still be better. like one of the first watt amps or something.
i find the HE-6 slightly bright, and could have better mids on the GSX MK2, but the transparency is a step up over HE-500, and the bass, oh the bass is much much better than HE-500, my favorite bass presentation right now. i do see room for improvement on the HE-6 with the GSX MK2, the good thing is that it does drive it, and it gets to good loud volumes, but its slightly shy of perfection.
