Received my cd8x just a few days ago and I am in the process of playing and repalying all my favourite cd's. I own a heavyweight 70's amp and speakers and I was worried as to the compatibility of including the cd8x into such a system. Over all, I am very pleased with the sound quality. The bass is solid and the detail is quite excellent. Yes, there is a little brightness in the trebble, which sometimes, depending on the recording, can sound a little harsh. However, for most well produced recordings, of all genres, the sound quality is excellent. The cd drawer is not particularly smooth in operation, but that can be forgiven in view of the generally good build quality and very good performance of this quality cd player. I may decide to invest in the external regulated power supply, but not for a while.
