Taksil , your Pathos can be perfect for any of these speakers, 30 watt solid state output will have some nice slam to it vs. completly tube at that price.. so don't be afraid to try the solid state on them, and you have some tube flavor on the input anyway of that intergrated, could be a perfect combo for any of the speakers in this hi-efficiency you seek!
And I actually don't remember where I found it, but They did compare the Victorys to Duo's stating the Victorys to have a superior integrated Bass to the Duo's, but found the dynamics more explosive with the Duo's.. And They have compared the Duo's to the Def's basically the Def's won out by far in the bass as well, and many other catagories, but If you can't hear any of these speakers for yourself you could make a mistake taking a leap of faith on a used pair of any of them on audiogon if thats what you are asking.. Of course I see no Definitions up for sale ever, but there are a couple pairs of Victory's and several Duo's all the time.
