The Alpha Dog is, to my ears, the best sounding fully closed headphone I have here--and I have a lot of headphones here.
When we attribute a sense of openness to a fully closed headphone, it's almost always with the for a closed headphone qualifier thrown in. To me, the Alpha Dog presents with openness, period.
And, again, this is essentially a fully closed headphone, not a semi-closed one. The qualities this headphone possesses--speed, neutrality, openness--are, in my experience, not common traits (especially all together) to expect from a fully closed headphone.
So if you sensed enthusiasm from me in the video, it's only because I'm enthusiastic.
Thanks for the Scoop Jude. I am in the market for a HD700 after concluding the HD800 would be too expensive to drive properly. Used prices on the 700 compare to what the Alpha Dog would retail for. Can you comment on upsides of either choice, especially in regards to amping? My thought was hd 700 with an ALO pan am.
