Steve and crew:

I had no idea the Zen Head was going to sound this good!  What an amazing little amp you've created...  If I were standing in front of you right now talking -- I'd be speechless!  I haven't even broken the amp in yet and it is glorious!  My iPod has never sounded this good!  My Yuin PK-2s -- Great.  My Grado SR 60s -- Great!  My Audio Technica M-50s
-- Great! I honestly don't know what to say except thank you for selling me this wonderful little amp!

I LOVE IT!
