High end bookshelf speakers for Small room

I presently am rocking a pair of PS Audio F5’s. These are some of the best bookshelf I have heard in my room. I own 10 different pair of bookshelf speakers and none of them sound to my ears as good as these. Some are Dynaudio Heritage, special 40, ATC 11, Buchardts SE, kef ls50, and R3 meta to name a few. The F5 sounds like a floor standing speaker in my room.  Very full and transparent. Bass goes very low, even at low volume bass is not wanting. You can tell lot of engineering went into these speakers. I

@deep_333 , reading your posts is probably the same as what cutting one’s self is like. There is nothing to be gained or any other redeeming value to it, but I do it anyway without really knowing why.

Without a doubt, PMC Twenty5.22i's.  I have them and run them through the same integrated you have.  They have a large sound stage and one that is fully rounded.  

I believe that Dutch & Dutch 8c speakers stand apart and above the competition as a small/bookshelf-sized loudspeakers. 

Having to deal with a small room after a move I pretty much have the same size as yours. I’ve had really good luck with the Reference 3a Reflector. It’s not a small speaker for a book shelf but I still run it with a pair of rel subs. I do turn the subs off sometimes for the hell of it. Sounds good with or without. 
 

I’m using a 50 watt class A amp switching between kt120’s and 150’s. If you’re looking for an extra warm slow fuzzy slippers speaker this isn’t it. There is something special about a speaker with no crossover. The 3a is not bright it’s very natural with a big wide deep layered soundstage that goes beyond the outside boundaries of the speaker. It can make bad thin recordings sound better than they should. The best part it plays all types of music very well.
 

I rotate other speakers in but always crave that ref 3a sound, I tend to use these more than the other bookshelf’s.
