So, here it is how I listen to music..
Left rack, from top to bottom:
Audio Aero Capitol tube amp, 2x50W in class A (comes handy warming the room during winter) - connected to Topping D10 DAC via RCA
Audio Aero Prima DAC - connected to Capitol amp (with XLR cables for no reason)
Denon DVD-3910 CD/DVD player - connected to Prima DAC via SPDIF coax
Rotel RSP-1066 processor - not in use
Rotel RB-1075 amp - connected to Topping D10 DAC via RCA
Under the TV you can barely see Topping D10 DAC and Raspberry Pi 3+ lying on Media PC which I no longer use. Right to them (white box) is Synology DS216SE with 2*2TB mirrored. Next to them is networking equipment (5GHz WiFi AP, 2.4 WiFi router, switch, optical to Eth converter etc.)
On lower shelf is Arcam T61 tuner I also don't use anymore and Android box for video playout.
Speakers are Castle Harlech S2.
