The most important component of an audio system is...balance. You need to balance the room, the components, and clean and plentiful POWER.
For example, put bookshelf speakers with 5 inch drivers and a 30 watt tube amp in a 5000 square foot room and I doubt you would be pleased. Have a beautifully decorated and acoustically treated listening room with cheap components and they will still sound cheap. Power runs through all of your components and a grungy power line will make things sound bad regardless of the room and the components. Balance is the key.
