I am pretty amazed to see that in all the posts regarding wires, parts, and so on, there is not a single clue that anyone here has considered the most important sonic accessory of all, namely their listening room.
Run, don't walk, to your nearest high end wallpaper and paint store and ask for the sample books on acoustical fabric. It goes up like wallpaper, comes in many patterns and colors, and will make your listening room so much better you won't believe it.
The object, of course, is to make your listening room "go away" as it is not supposed to be part of the musical performance at all. All the sound spattering off of your floors and walls is dead wrong, and painfully obvious to me. All the wires and cables in the world won't help this a bit. Well, if you had soft fuzzy wires and you wound them completely around and around the room till the walls were completely covered, that might help.
Any acoustical output or reinforcement from your room is wrong, it was not part of the recorded acoustical enviornment. And you can do something about this inexpensively and usefully. Acoustical fabric, heavy drapes, cork tile, even rough surfaced brick -- anything to kill and reduce room reflections.
The next time you are temped to spend another $500 on wires, spend it on acoustical fabric instead and achieve some real results.
