I don't think tubes would be the way to go in this situation. If you are going to use a single 5 channel amp, I would recommend an amp with quality solid state power and beefy transformers.
Krell, Plinius and BAT are a few brands that come to mind and are great matches with Eggleston's.
What's your budget?
