I highly suspect the sound is straight out of the speakers / system. In order to achieve soundstange width / depth and the instrument separation in recording of this quality, you will need to place highly sensitive microphones (shot gun preferrably) 2-3 feet in front of the speakers, which we do not see at all... On a flip side, the YT music SQ is getting better and better. Several credible youtubers have commented similar. The titles are even more available than some music servers like Tidal.
Name this wonderful system
Just took a listen to system on YT now. My oh my, this one is quite special. For bookshelf speakers the results are even more impressive given their size. The creator of the video on YT did not provide any details on the system specifics.
From looking at the snapshot of the pic taken from YT, what do you all reckon are the speakers , the preamp/amp and DAC/streamer?
I have reached out to the person who uploaded the video for info, however they seem pretty close lipped and mentioned they have many systems so hard to know for certain.
