^^^Ableza, a big +1, your advice led me to the Alpha Dogs. I have had mine all of 4 hours now and I agree (though I have put a in one Dog Treat per side). I am fairly new to HeadFi, not to Audiophilia, but these AD's are the best I have ever heard. I really didn't understand when others referred to the HD650's as "grainy", now I know what they were referring too. With the Alpha Dogs the music rises out of a deep, silent "blackness". Sound staging and imaging are excellent, closed-back, no problem. With the Wyrd>Modi>Lyr 2, these baby's rock, it's early, but I don't see why anyone would want to mess with the bass adjustment.
MrSpeakers/Dan, well done, these are exceptional headphones, more to come after some serious listening.
As I told you in PM, the Alpha Dogs caused me to relegate my HD650's to a closet in storage.
