4.5 quality at a budget price bhavjit | 12/05/2009 | See all bhavjit's reviews (7) ive had a few surround systems over the past 5 years from the original davs 300 to the is50 i installed and setup the Sony dz630 for a friend and was amazed at the clarity off the sound i wanted to test the 5.1 surround on this system so i put in saving private Ryan a good test for any system. I was amazed how the systems sound separation was so accurate you could hear every crackle bullet ricochet, explosion in detail the subwoofer was very intense and worked well althogh i would advise on setting it higher in the sound menu. dz630 auto calibration worked well and set all the speaker distances correctly i would still set the rear speakers at higher decibels in sound menu. inportantanly i was most impressed with the upscaled image to 1080p by the dz620 the picture quality was almost like hd. playing music through the system was average but can be improved by using the diffrent sound setting, the speakers look slim and sexy and you can wall mount them if you want, build quality is the usual high quality you expect from Sony. overall you wont be disappointed does everything you need upscales all your old DVD collection to 1080p and does it good. just 1 minor flaw is there is no optical input just analogue input.
