A small overview of the modest system.

Are those DIY speakers?

Yes. Before that, there were other excellent speakers Acoustic Vienna Grand Hyden
 

Good choice on Yarbo. The best system I have heard uses the 9000... Can't source it cheaply for my system though.

I have a simpler version of the YARBO SP-1100PW, but in comparison, even with very expensive cables, this option is not bad either on the amplifier or on the power supply.
 

The main thing was turning off the local APIC, which at once solved a lot of problems. And the main thing aligned the upper frequencies, the voice became as close to human :-) and the sound scene ceased to change in the process of composition.

If memory servies that is the setting that will disable virtual IRQs. And that is a revelation. Funnily enough some motherboards will not boot with this setting, and it's the reason why virtual IRQs are enabled by default.
 

and ... I apologize in advance for my English ...

Your English is fine.. And it's better than mine . 

It is for this reason that I chose a very simple motherboard from Intel with an Atom processor.
For any tasks related to sound enough for even one core? no need to think about cooling and power consumption, fast and reliable network controller, the ability to use different Wi-Fi cards, it's a pity there is no way to install m-sata SSD in mini-pcie slots.

P.S. By the way I'm waiting for instructions on loading Snakeoil through PXE! I want to try to get rid of one more device - SSD.
