I have owned a lot of equipment over the years and have listened to even more.
I am not going to list it all here because a lot of it was/is fantastic and I would be doing it a disservice to pair it with the next comment.
The Shindo equipment does not do everything sonically necessarily any better than a lot of other equipment.
What it does do, for me, is, almost every time I listen to it, shift my focus to the music. I do not mean it is more transparent, dynamic, PRATty, or any other adjective you can come up with. I mean it somehow allows my mind to more easily grok the music. Any kind of music. I don’t know why. But it does.
