I can't speak for the Dehavilland but everyone that's heard my Aurieges has loved it. Just keep in mind that the impedance on it is quite high, 5,000 Ohms, so you have to be careful about matching amps with it.
I believe the guideline is that the impedance of the amp should be at least 10X the pre, so at 45k its on the borderline.... I believe that my Bedini amp is about 45K Ohms, and it does work with my Aurieges but YMMV. Maybe one of the experts can chime in....
However, if you match with a tube amp, like what Jonathan said impedance matching is less of a concern.
