That sound is right for me.

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.

You are absolutely right! When I listen through headphones, I enjoy it very much, this guy is truely making the  amazing sound. It will be a lot  better if listen in his room, I believe.

Limited in hifi record is really becoming a issue for us now. We need break through of hifi idea. Thanks.

There are lots of aspects with the sounds.you are right with the fidelity of the sound@cleeds but I still can judge out that is sound I  am asking. The whole structure of sound is revived even through YouTube. 

@baylinor  it's meaningless to say my English good or bad here. If you are not clear for whatever reason, you can just ask me.

Does that work for you? Let's go into the topic.

@clearthinker ​​​​​​ He is not doing business, and  does not sell me anything.

He said he made the preamplifier and amplifier by himself and I believe. That's it.

@henry53 I am not going to headphones listen for myself. I talk about preamplifier and amplifier. If you use your amplifier to play the music and post on the YouTube, and let others listen through headphones, it will be another story.

If that happened, you can compare with this guy. I know cayin make some good amplifier, but not that good.

@baylinor ​​​​​​I write it flat clear, and what is unclear to you?

Let me know.

@uncledemp  you are definitely go into the core. He replaced the original crossover of the speakers and redesign a new tube crossover for the speakers and he said his crossover is much better. So now I have some clue, it is not just preamplifier and amplifier. 

I have several time listening Altec speakers at site and felt extra  well each time. These are all old equipments and some one can handle it if there is small problem, and I am not sure I can handle it.

In another topic, we are discussing when is the best time to make the best hifi device. And some professional guys said it is now.  So I am wondering if I can buy the current model  with such good sound?

 Thanks very much @jasonbourne52 ​​​​​​, we are  in the  almost same position to understand the sound.

I just can't handle old equipments by myself.

@clearthinker As I said before, some one might not agree, if we can do assessments the hifi system via headphones listen on YouTube, you are one of them. I respect that opinion and we do not argue about it. Let us keep the difference between us. I said we could do that in rough idea, not very precise way. Someone agree with me,some one not agree with me.

Let's not argue about it.
