The Viva Egoista is stellar with the HD800-first tube amp I don't nor will I roll tubes. If you get a chance to listen to this amp it is magnificent for all headphone but excellent with the HD800,
I bet thats a KILLER combo Frank!!
I've been basking in this HD800 system this weekend:
Those new Double Helix Cables Complement4 dual XLR have also become my #1 choice for the HD800 and my LAu!!
The sound is lush, dynamic, wide-open/airy - and there's more soul in the music than I've heard before through my 800s.
I've always loved them technically, but not always with regard to connecting me to the emotive power of music.
But, in this system - they're a real treasure!
And those NuForce HA-200s in monoblock configuration do a FINE job w/ the 800s too.
