WOW, I guess I am an old and boring man in this forum since all my life, I have been in search for the most NEUTRAL sounding pre-amp/ amp/ speakers and they do not come with a small ticket. I don't find NEUTRAL to be BORING . On the other hand, I do not understand while people want to listen to colored sound.
I love my HD 650 even though they do carry some Senn signature as a bit colored but vocals or small piece of jazz , they are preciously designed not BORING. The AKG 702s are not BORING either but they could be if you think NEUTRAL is BORING. The AKG 702s have an immense wide soundstage and they are a heavenly pair of cans for acoustics, blues, jazz. Yet, the AKGs are very NEUTRAL. They more neutral than the HD650 and there is no doubt about that but that is why the AKGs and the HD650 are appreciated among the audiophiles.
