Finally got the package in, and got a chance to review/use it. The micro SD cards sound wonderful when using it as a source to playback with the stereo or headphone setup. Blue Note did an excellent job re-mastering the recordings. The books are a nice touch, and are very informative. For those who are into vinyl, this has much the same enjoyment with using the book as reviewing the album cover (more,in fact, as there is a lot of information and pictures provided.
The AK 240 player is also a very good sounding unit. To me, it sounds somewhat better than the AK KANN.
Overall, very happy with this.
