Yes, had the opportunity to listen both extensively. The DPL is a bit too slow and dark sounding for my taste. Yes its lush but it lacks details that the M2 can flesh out very well. The M2 is a modern sounding preamp comparable to a fast, detailed, transparent s/s pre-amp yet never fatiguing, harsh. The M2 matched also well to a wide variety of gears, the DPL matched well to jadis gears, plinius, krells. Overall, I'd take the M2 over the Jadis.
