That sound is right for me.

I don't understand the question, or how you could now that it is the sound for you over headphones from a youtube video.

sorry! I miss a word " level" ,I mean that high level of sound. Yes! I got to know it through headphone, May not everyone agree with me that people can listen to know through headphone, but I do.

I will not talk of a lot of that point, but if you are experience enough you can get the rough idea of that sound through headphone.

Please listen through headphone of that youtube video, before you comment here.

Thanks!

and I am always go to the tube pre and tube amplifier same as the video shows. so do not suggest SS ampifier as there are a lot difference here. Again,I will NOT talk of a lot of that points,as some one might not agree.

What I ask is to buy such machine in the market to have that level of sound, I do not want to argue with anyone for any points.

The issue here isn't that you're listening using headphones but that you're using YouTube. It's difficult to judge fidelity from such a lo-res source.
