Need Help Choosing a Tube Preamp for a Classe Amp


I have Thiel CS3.7 speakers and a Delta 2200 Classe amp. I'd like some suggestions for what tube preamps to audition to match with this amp/speaker combo. The Thiels are wonderful but unforgiving of things like tube rush and I have little interest in tube rolling or high maintenance. The Classe Delta is a fairly neutral SS amp. I'd rather not spend more than $3000 used...or is that unreasonably low? I've listened to the VTL 5.5 and was impressed.

For many years the "synergistic" combo was Audio Reasearch pre, Classe amp, Thiel speakers and all MIT cabling. I have followed this guide line with great success with Thiel 2 2s and 5is. Pre's were LS15 and Ref1. Amps CA100 and CA400. Cabling MIT 350 Ref and 850 Ref.
the VTL 5.5 is supposed to be excellent. I have a Cary SLP98 that I love--extremely quiet, "neutral", looks gorgeous. ARC & C-J worth checking out of course.....
Samhar beat me to it. You can move the jumpers by hand. You just need to unplug it for a half hour to let the capacitors discharge.
Phono stage is NOT a necessity. Thanks to everyone who's posted so far. All of the information is highly useful. This is why I love a'gon.
