HighEnd Novum PMR Premium MK III (Passive Multi-Vocal Resonator)

Novum PMR Mk2

What it does for sound is obviously beneficial for my set up. There is a slight gain in loudness at any given knob position, but the gain is not unpleasant. The treble is somehow restrained but gains in detail. Decay is extended but not unnaturally - there is no adverse "feedback" or "ringing." The mids and bass seem somehow boosted but with no distortion which was an apprehension I initially had when first unboxing it and just looking at it. Notes "seem" to linger longer but there is no sense of undue embellishment. A lot of the music I favor such as Deuter already has echo in spades, but the Novum does not just tack on extra echo - it seems to simply grab what is there and stabilizes it so that it "behaves" with more composure. Very strange and delightfully so.
