Speaker day! KEF R7 MAT walnut

Greatings, this is my new speakers, to complete my 5.1.2 system driven by an only Cinema 40, the room correction is OCA A1 Neuron 2.5. For the first time, All of the speakers are the same MAT series and a KC92. You can see minor QC issues, I rob a nut on it but still visible when you get closer BUT I can say the soundstage is phenomenal, the R7M have for precise bass, imaging, specialisation is out of my expectations. Next steps would be : acoustic traitement, another Atmos pair, a screen and a projector. I listen music at mid level in general and I push a bit on films. I wonder if I have to go with cinema 30 or adding a buckeyes power amp.. Well, it is a bedroom and I don’t have so much choice for surround placement but the unis do an amazing job. If you have advices, please tell me! Thanks
