I am a big fan of the Purist Audio Design "System Enhancer Ultimate" CD..It assists with burn-in and it demagnetizes the system. Play it at moderate volume on repeat. You will notice a difference in your system after burn-in. Be patient and enjoy hearing your system come to life!
Value of burn/break in?
I have my first hi end audio system. I fired it up, popped in a cd, and it doesn't have the vibrant sound that I thought it might have. I have a slightly used demo power amp from a dealer, slightly used demo speakers from a dealer, but a brand new tube preamp. A friend of mine told me that I will see a huge difference in sound quality once the tube preamp breaks in. I was wondering if I should get a break in cd or just wait till normal listening does the job
