There are some tubes that light up quite brightly with a white rather than orange glow. I think they are 845s(?) - someone help me out here. I don't know if there are any amps that use lots of these, I did see an ART audio amp that used 2 per side (I think it was a Carissa, not sure), and it looked stunning. Maybe more than you want to spend, but there mustbe some inexpensive Chinese amps that use these tubes.
I also second the Atma-Sphere Novacrons - fabulous looking. Also the M60 owuld fit your requirements, but you should have efficient and high impedance 8ohm or more) speakers. MA1a would be great, but used around 4000 - 5000$.
