Well, I would buy the newer HD800 S myself, only because I prefer flat treble. Regular HD800 (not the S model) and T1 are both bright. I think technically HD800 is superior, T1 has more bass. You should audition them. Sadly I don't know much about receivers. That said, if the receiver's dac has line-out, you should be able to connect it. You should check the manual, I think.
