Bose is a name that signifies quality and that is exactly what you get with this system. It is a DVD/CD Player and Radio all in one. The GXSL model has preloaded music by Bose with room to add your own music, about 10 CDs worth. This UMusic system comes with an intelligent playback to suit your mood with a simple press of a button. Simply put, if you find a piece of music or song that you like, you press the button and it will then source all other pieces of music or songs within that genre. The radio has AM/FM and comes with both aerials. You are provided with a set -up CD which is very helpful and easy to follow. The unit comes with two small speakers that are capable of big sound. As with all Bose speakers no technical specs are ever given on output. These with the acoustimass module gives any movie the cinema effect when used with your television. The only drawback is that it obviously will not play Blu Ray discs, but this can be overcome by adding a Blu Ray player as another component through the Bose system. Most leads are supplied to connect your Bose system to your TV but other components may require additional leads. For sound clarity this system is second to none picking up on many background sounds you may not have heard on your movies before. As for the music it sounds as if you are sat in the room with the artist. It is quite expensive but you do get what you pay for. The Bose website will give locations of stores in your area with sound booths that enable you to hear before you buy.
