Speakers selection

Hello, we have created a new SET Class A amplifier monoblocks giving 140W RMS, all in pure class A. We are thinking of commercially launch this, because they sound absolutely fantastic regarding atmosphere, musicality, dynamics, detail, bass extend, clarity, stage, voices reproduction. Nothing like we have ever heard before upto 30-40k amps. We have carefully design it to be the fastest amplifier possible. 
We are in the stage where we invite some shop owners and dealers to listen to the amplifiers.
The speakers that match the amplifiers currently are the Focal 948s and exist in a room 25 sq.m.

Now the issue and problem. One of the dealers was puzzled by the extend of the bass (it really moves the couch). He also noted that there is some air missing in high trebles. This dealer has the McIntoshes in my country (not US) but he admitted that our amps beat twice and more the price systems in all other aspects.

So we are thinking that 948s are not suitable for the room and maybe we could move to other type of speaker so it would give us less bess and better highs than 948. I have used the amplifiers with more than 88 db sens and did fine. However did not like much my Magnepans 3.6 (85db sensitivity). 
We put a budget of 8k euros for this, and thinking something like B&W 805 d3, or Focal Sopra 1 that are on stands.

What do you think? Would these give us less bass but really better highs? Please if you give a recommendation, have lived at least some time with the speaker you suggest.
