How would you define better? Remember better includes different. You might change a component and hear differences that you will then say are better. Some will say better means more accurate sound but then have trouble defining accurate. My system has also reached a level of enjoyment that I have no intention of making any major changes to. I still have fun by playing around with tweeks and cables for not much money. I even found inexpensive cables that sound better than my expensive ones.
