Default Thoughts on this phono stage?

Hi,

I often check vinyl rips on youtube. There is a guy who has the best quality rips of my favorite songs I ever heard on youtube . Ability of resolving background details and separation amazes me. He states that he doesn't use external preamp, only Technics Su-8011's phono section. He also states that using an external equalizer.

I grabbed service manual of Su-8011 and I found that a pretty simple phono stage. I wonder if the sound signature that he got is the result of phono stage or external equalizer stage. Have any opinion on this regard? I'm attaching schematic.

Here is one of his rips:

Thanks.

Seems unlikely that he's' using no post processing, IF he has better quality than others - he may also be aware of the max level that Youtube can take as input, and keeps his levels proper. But somewhere in there he has to go from analog to digital, and that requires software and a computer - if he is not saying what he is using there, then he's not telling the whole story.

There is nothing special about that preamp.
The cartridge would likely make more of a difference.

It looks like a fairly standard sort of design. I would say that the sound is mostly due to his EQ settings.

there's no surface noise evident... no needle drop... seems highly processed, or else faked and that is a CD transfer and an LP video. Anyone hear surface noise?

I heard pops at 3:29-3:31, so it seems its vinyl all right. Can't judge sound quality because I listened on my laptop. In any case for youtube any preamp will do OK I guess.

Actually his rips way better than CD releases that I have. Probably due to poor and clumsy digital mastering process of CD's.

Here are two versions (CD & Vinyl) of same recording:

My listening on youtube is meaningless...

there are inherent differences in the masters uses for LP vs. CD in the first place. There is lower S/N on LP... mono bass, etc...
