I have been lucky enough to have both the WA6SE and WA2 side-by-side for a while and have spent the past couple of weeks listening to both amps. I should be finished the review over the weekend and will post it when it's all done. I primarily wanted to know for myself if the WA2 was inherently better than the WA6SE for the Senn HD800. I will attempt to answer that and more. Like, what are the differences and similarities? At least to my ears anyway. It's been fun anyway and I hope it's an entertaining read either way. Thanks!
