Audio/Video Room Integrated Setup And Listening (L20D, B&W CM9, SMSL Sanskritt, REW, Daphile)

This is my audio room, I'll re-upload in 720 or 1080p. In the 19" bay in the backroom there is : - a 1U server running Daphile with 3x USB ES9023 DACs (one for the bathroom, one for the office, one for the living room), and one Sanskritt DAC for the audio room. - a MacMini for Plex (video playback to the 720p video projector mounted on the ceiling), connected to the Sanskritt in S/PDIF - a 1U HPA D604 4x150W 4 Ohms class D amplifier for the living room and the office (the living room has two Focal Electra 1008 Be) - a SMSL SA50 2x50W 8Ohms class D amplifier for the bathroom (the bathroom as 2x Focal IC-108 in ceiling speakers) - a 3U home made dual mono class D amplifier with linear power supply (2x300 VA, 80 000 uF), outputting 2x200W @ Ohms within 1% THD. For the audio room (the audio room has B&W CM9 speakers) - some cat7 and cat6 cables and speakers cables coming from different rooms thru the walls. The bathroom has impulse filers loaded into Daphile to correct the frequency response. The audio room also has impulse filers loaded into Daphile, but much less aggressive (shown in the video) to reduce the peak of bass at 30Hz mostly (causes by the length of the room). Only the audioroom has decent acoustics, so I'm thinking of selling both the CM9 and Electra 1008 Be for better speakers to put in the audio room.
