So I have a pretty basic entry level setup with an Audio Technica 120, a Sony Stereo receiver, and some Klipsch bookshelf speakers. To me my setup sounds pretty impressive but I would definitely like more power and depth to the sound. I'm already looking at getting some nice floorstanding speakers but I ultimately would like to invest in some standalone components like pre amps and power amps IF they really make that much of a difference. I really don't have anywhere local to go and listen to such a setup but what do you guys think? Does it sound that much better and what are the key differences? I assume there will be cleaner sound due to less interference which would be great...
