This Sony CDP X1ES Single CD Player is the perfect addition to your home audio setup. It's a rare find for audiophiles who appreciate high-quality sound. It has a very good bass response and has an Advanced Pulse D/A Converter. The unit works great and is in good cosmetic condition. It has a small mark under the shuffle button and a few light scratches on top as shown in last four photos. They are more visible in the photos than in person but I thought that I would point them out.
