Need suggestions on efficient book shelf speakers for a Pass Labs XA3.5


*sorry amp is XA30.5 -will not let me edit headline.
My current speakers are KEF 201/2 which have a low sensitivity of 85. Amp is only 30 watts class A. Sounds good but the volume is limited. Hoping more efficient speakers will provide greater volume? Looking for suggestions in the $2k -4k used or $3k- 8k new.

Hoffman’s Iron Law:  For a given cabinet volume, sensitivity and bass extension are interdependent variables…no amount of money will change that. If you define your bookshelf speaker by size, increased sensitivity will necessarily mean reducing bass extension. Is that what you want?  

I would look into Tannoy Autograph Mini's...I am exceptionally impressed with mine, driven by a Manley Stingray...in a 17x25 ft room with cathedral ceilings

I recently bought a pair of Goldenear Technology BRX monitors. They are 91 db efficiency & $1598 per pair. They are excellent with a great soundstage & especially good on vocals. I love them.Â
