Jadis DPL2 preamp: is it Good?

This reply is more of an opinion. Of the pre's mentioned I would guess the Jadis would be the better choice. Yes,they make more/better/expensive pre's than DLP2. Having owned one of their amps; hope that you don't need service and have to contact the distributor for anything.

If you could get a Jadis preamp for a nice price, you do not have to think twice.
I have been using a Jadis JPL for the past 10 years. I finally settled on Jadis after going through some top solid state preamps like Klyne and Spectral, and tube preamps like Matisse and old Marantz 7. This Jadis gave me utmost satisfaction without any breakdowns which many people fear for tube amp, as it is of a very simple and reliable design.
It scores full marks on air, warmed, musicality, soundstage and sweetness. The only weakness is a bit light on bass. It is superb for classical and jazz but obviously not the best choice for hard rock or digital sound.
To make a Jadis sound best you got to have some vintage tubes made as early as the 50-60s. Tubes made in Russia and China nowadays simply are not of the same class.

Yes, I can get a new one (in France) for about 1500 US$.
