I know that in the end it won’t really matter seeing as how they’re probably so similar but i really do wonder which to purchase. On one hand, the HD600 has more details in the audio. On the other, the HD650 has a warmer tone which I’ve heard makes it more fun to listen to, and a wider soundstage (not sure if this is true or not but it is what i heard). I’d like to hear your thoughts on this. I know how often it’s been talked about but this I’m left with the question
