... overall , I be very impress by the quality and value of this product . the system provide plenty of power for anyone with a small to mid-size room , and the clarity be better than one might expect from small home theater in a box speaker .  the heart of the system be a 500 watt receiver build by Marantz -lrb- although sell under the Philips brand name -rrb- . the receiver have all the bell and whistle one would associate with any upper-end receiver . it have a wide array of input , and feature interactive menu that allow you to enter distance between speaker to properly adjust the volume level between the speaker component . all buyer should be aware however that this system do not decode DTS . you can only get Dolby Digital out of this machine . in my humble opinion though , it be virtually impossible to tell the two format apart unless you be use high-end equipment .  the only realy drawback I see be that the reciever only have one digital optical input . if you be like I and have a dvd player and digital cable , that create a dilemna . it do have two coaxial digital input , but I personally do not like coax input as well as digital optical .  the speaker be far better than those include with similar system by other manufacturer . the three array design of the center channel speaker be a nice touch and the front and surround channel be well compliment by the 100 watt subwoofer . when you turn it up , this system can really kick .  if you want solid quality at a low price , this system be for you . it provide plenty of power for the average user and will add a whole new world to you home theater experience .
