Honestly, the DeHavilland UltraVerve III is at the top of my wish list. However, as you know, these only rarely pop up for sale, and the vast majority seem to be units without remote control.
I'd like to push back very politely about this a little (totally friendly-like!).
First, I set an alert for the DeHavilland in USAM. I was surprised they came up somewhat regularly. To test my claim, click HERE (HiFi Shark) and search Used/Expired and look at the dates.
As for remote control -- someone might be able to add one.
Second, the Cary preamp has SIX 6SN7 tubes. That's a lot of tubes. The Dehavilland has one.
Third, I had the Quicksilver Preamp. It comes up used often. It is quiet and sounds good but a bit dry, clinical. No tube changes made that better. I think the 6SN7 is a better preamp tube.
