It is so true that the sound is coming out of the system which contains a lot of things.
I try to replace my 4tc speaker cable with 12tc speaker cable, which is much heavy. I think it will be better sound, you know what? The sound is more tube like,but slow.
I can not stand with the slow sound and I changed back and found the original feeling. What feeling? Once I have the time, I won't stop listening.That is really magic things to me.
