Diffusers are old styled kind of divider for the dressing room, not really sure, spotted them in some store. I actually repositioned them and will update the photo after holidays. There is some more damping material on the inside. I also moved motor from turntable further away from platter and added more silent phono Accuphase c27.
Wow what a set up - Love it. Looks like you have 2 Turntables. If you have issues with dust resting on the platter check out Dust-o-disc great for keeping the platter clean !!
As I have bought them with slightly chipped base I have drilled m8 holes added some threaded elements and screw in finite elemente ceraballs. Now I can also control angle in a very easy way. In the future I'm planning to order custom made probably basalt bases. Lyra Delos - i like it a lot. I have it on Reed arm and like it - best sound i got in my setup so far but still a lot of cartridges I would like to try. Listening remastered Callas live at the moment. I think this is best combination of detail and imaging. I'm still unsure if this is my go to cartridge. Tracks very well, midrange is very liquid and real and it is very extended but without being fatigue. I still have zyx that need to mount - for a long time i thought it was broken but after close inspection looks like body is not glued to the base properly (misaligned) so all my attempts to align cartridge failed due to this fact.
