I'm with doorman, if you pass these up you'll kick yourself later. I quick glance over the review on SoundStage and the speaker review in Abso!ute Sound would have one thinking this may just be a very synergistic pairing.
Speaking from experience I would then recommend you search out a Wytech preamp as generally you'll get that synergy in spades with electronics from a single mfr. My current setup of a VAC CPA-1 (with VAC updates) and pair of VAC PA-160 amps has without a doubt been the best combo I've owned. I've owned pairings from Quicksilver, Audionics (tube pre, SS power), and Audio Research. I always had either the pre or the power amp first and then acquired the other later and always the synergy was obvious. The same has been true with most of the solid-state gear I have had. And, yes, I've stumbled across some pairings that just didn't sound good.
Just my .02
