I'm not shure, but i believe plinius and ARC preamps are very different. M 16 is a very good preamp, i have compared it with an cello omega one preamp, and so the plinius is more realistic and true than the cello, but with the cello encore monopower blocks, it's different. But in using Quad ESL63 pro and plinius amp ( a SA 250 or a SA 102) and sonic frontier SFD1 mk2 and Audiomeca Lurné Mephisto, from our pointviews (me and two friends) the M16 is more true. But music is subjective.
