If you really want to drive the Dunlavy's right, I would stretch your budget a little bit and get the VTL MB-450 monoblock amps. (Used they go for around $4,500, but you can sometimes talk the sellers down a little, closer to $4K.) They have lots of power to really get the most out of those speakers. (The bass response of the MB-450s is about as good as it gets for tube amps, unless you can spend double or triple the amount.) These amps sound really good, and have a nice touch of tube bloom in the mid-range. Not so much as to be considered bloated by any means, but just a nice touch. The treble is nicely extended and refined. Soundstaging and imaging is excellent as well. A true top notch tube amp in my book.
Cavaet time:
One, They run HOT. They will raise the temperature in your room several degrees, unless it is air conditioned.
Two, While they have very good bass response, (I consider it to be great bass for a tube amp), it can be bettered by equal quality solid state monoblock amps. (But then said solid state monoblocks don't have that nice mid-range either!)
Three, they have 10 tubes per monoblock amp, so retubing them can get a bit expensive, as can tube rolling. (But hey, that is what tube amps are all about, right?!)
Good Luck in your search!
