I have spent a day with the QLN P1s. Quick summary is that are good monitors and probably warrant the cost. The midrange is very solid and natural sounding, soundstage and image are good, and they excel at laid back music like Bill Evans, Diana Krall, Laura Marling, etc. However, they are VERY “laid back” and lack IMO sufficient detail, air and punch to be considered a great all around speaker.
They do not generate excitement so much as a relaxed satisfaction. Case in point. On the BS&T song God Bless the Child, when the horns first come in I am used to feeling their impact and “punch”, and it puts a smile on my face. On the QLNs they had no impact. It was as if something was missing compared to other speakers I have had in my system.
Dealer says the P3s will have a similar sound profile, which is good, and will add more detail and punch due to a better crossover and larger cabinets, plus better foundation (the P1s are sitting on stools, not optimal). I am undecided. If the P3 substantially improved on the P1 weak points, I think I would be happy with them. But if the improvement is only minor I am not sure.
I think I may try a pair of Zu Soul VI before I make a decision.
