In this whole discussion I miss one thing: Output Impedance!
I think the HD800, like all the other Sennheiser phones, are designed to work best with very low output impedance of the amp. That's also the important factor, besides sheer power, to make the 'Veil' vanish on HD600/650.
On the other hand, AFAIK the Beyer A1 got a output impedance of >100 Ohm and so the Senns won't sing on them.
The impression of the sound by mOgwai backs my theory, because I experienced similar behaviour with some cans on high ohmic amps.
