Thanks for the review.  I'm right with you on the dimensionality of the Alpha Dog.  It was never really there with the semi-open stock T50RP and Dan's closed version is not worse but improves upon the soundstage.  A limitation of the driver?  I miss my ASG-2 which did do a better job in regards to depth.  I also agree that the Alpha Dog probably won't be one's only headphone.  Is that even possible in this hobby        

Thanks!
 
At the end of the day it's definitely different from the MD, but I'm not sure someone who loves the MD will find the AD a direct improvement rather than a sidegrade.

I'm also wondering if it's a driver issue. It's almost like it can't make images "materialize" like they would in real life. Still, a great job by Dan, given what he had to work with.
