Bookshelf Speakers?

Downgrading so I need some advise or opinions on a good pair of high efficient speakers, 90 and higher db. Looking to pair it with a Primaluna Integrated amp.

Second the Triangles. You could also explore some floor standers like Triangle Antal and Celius... 92 db sensitivity and easier to drive than the Cometes.

Reference 3a or Coincident Triumph.90db + and a nice high impedance will serve the PL2 best.When taxed hard the PL@ can start to sound flustered,untaxed it is a sheer delight.
I have not yet heard the De capo's (reference 3A) but they are on my list. I saw a nice pair of Zu Audio Tones on here and gave it a thought. What kind of sound do they have? I heard the Zu Essence in town and was impressed but $$$$.
I love triumphs but sorry Celtic66, they are 2 way speakers. I'm looking at mine right now. Originally, Coincident had played with a concentric/coax single driver way before the triumph. I also have Conquests and Mini Triumphs. If you don't need much bass, the mini's are amazing. (my theater is coincident).

My second choice would be PSB stratus mini's.
