Don't feel confused if you don't know what 'high-end' is. That term is something that hardly exists these days because of places like BB or CC. The world of HiFi is nearly non-existent in popular culture. Sometimes you don't know good sound until you actually hear it and that is where we can help, because the people here are the last of a dying breed and we are trying to keep the world of HiFi alive, although it will probably remain for the minority, and some of us are OK with that too.

I would also echo someone else's comment about searching around and seeing what else is out there, but also it's about what you want to accomplish...do you have any audio goals?

It's easy to hit a target when you have an idea what the target looks like and that will come by going around and testing some stuff out. Your eyes and most of all EARS will be surprised what is out there... good luck.
