Thanks a lot for the responses. I'll have to look into some of the suggestions, but at least it looks like a decently powered tube amp should be able to drive them. I'm not sure how it works in the audiophile world, since I'm just starting to get into it, but I've been playing guitar for a few years and the 2 amps that I have are both tube based (KT-88 and 6L6). I've tried solid state in the past and they just don't compare to the tube amps, so this is one of the reasons why I'd like to pick up a tube amp. Also, I'm used to letting my amps warm up so that won't be an issue with me.
