Rebuilt crossovers in multi $K speakers a few months back with good quality, not expensive, parts. Immediately after, the speakers had more dynamics and life. Good recordings really stood out as much better than average recordings. A very disappointing experience was AC/DC Live CD. A very thin and irritating sound. OK, chalk it up to a poorly mixed live recording. My favorite music and artists were very pleasing, so AC/DC goes back on the shelf.
Yesterday, in the mood for some pin your ears back rock and roll. Gave AC/DC Live a try that had not seen the light of day in months Did somebody replace my CD in the dark of night? The difference was too great to ignore. Sounded Great! Is it possible burn in made the difference?
