Now I have made further steps:
- my electrician moved the Furutech wall socket from the living room and installed dedicated mains. The power supply now runs separately from the main distribution board to the sub-distribution board (fuse box) with separate grounding. He installed a Doepke DFS 2 audio RCCB Type F. Unfortunately a Gigawatt G16A was not possible because I need 13A. So a good standard circuit breaker was installed.
- also my electrician installed an Ethernet wall outlet in the listening room and a Cat6a U/UFTP cable to the Cisco 3560 in the garage.
- I bought a used Naim Fraim Lite. Unfortunately, no used Full Fraim was available within acceptable distance. However, I installed a tempered glass plate with silicone nitride ball bearings and brass chips on the top level (following @Xanthe approach here on the forum). I still plan to buy Fraim Chips under the floor spikes.
- The system was moved from the living room to the new listening room yesterday. Everything is still provisional. I still need to optimize the speaker position and determine the frist reflection points. After the summer vacations (in 3 weeks) I plan to order room acoustics elements from GIK. The cabling is also still provisional (the Ethernet cable from the wall socket is too short, the power cable a bit too long…).
But overall it already sounds quite good. However, the reverberation time is still too high at 1.2 seconds.
Thanks to all who have supported me so far, especially to @feeling_zen @Mr.M @Simon-in-Suffolk @PeterR @HappyListener, for your technical input.
