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.

How about the First Sound Presence or Wyetech Opal? Is a phono stage a necessity?
The top of the Calypso is held in place with Velcro, for easy access, replacing the tubes and changing the gain setting are simple. Amperex 6922 PQ are $200 a set or Mullard 6922's are $280 a set and Mullard CV 4004 are $180 a set.
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.
