Ohhhhhh baby.... To anyone that has a Stellaris on order, you are in for a treat with your new amp. I know it is a lot of money, but Donald delivers. Mine took 60 - 100 hours (maybe it was the tubes?) to really hit its stride but once it did, wow. The Stellaris is exceptional. It's smooth without glossing over anything. The dynamics are incredible - it doesn't lose pace with anything I throw at it. I have to admit, at first I was not overwhelmed with my new amp but given some time with it (finally) and some burn in... I don't mean to sound like a blubbering idiot but I feel like it combines the best of all the worlds. Right out of my source I get silly good detail and resolution and the Stellaris preserves all of that. With a big iron amp I get the separation, 3 dimensionality and impact and the Stellaris brings that. With a tube amp you get that sexy 3rd order distortion that we all love so very, very much and the Stellaris is right there with it to grab you. I've had this moment before, where I question the HD800's. After all, why on earth would I have such expensive kit behind such modestly priced headphones. Turns out they still deliver with the best of the best. Sorry for the rambling.
