this be a excellent entry-level system -- and you can not beat the price for the performance . if you want a solid 5.1 surround sound system for less than $ 200 , you will not find a better one than the Sony ht-ddw660 . my friend with a Onkyo super-system be amaze at the clarity and depth I get out of this simple Sony -- he say it be every bit as good as he $ 1,000 + system , albeit with fewer bell and whistle . I install this with my Panasonic HD tv and Hughes DirectTV\/TiVo HD receiver use a optical cable -lrb- which you must buy separately -rrb- , and the Sony system automatically switch to the optimal sound configuration on the fly . excellent for the rest of my family who do not want to fiddle with the remote . the digital coax connection make hook up a dvd a breeze , too . I recommend that you also buy the optional speaker stand -lrb- Sony ws-fv11 -rrb- which will cost you another $ 200 for two pair -- odd that four speaker stand cost as much as the actual system -- but they be worth it . my only -lrb- all minor -rrb- complaint be : - the power be a bit low -- you really have to crank it up to get some strong volume . if you have a big room for you home theater , get a bigger sound system than this . - beware switching to FM radio before turn the sound down ; for some reason , the volume level on the radio receiver be MUCH higher than for the tv\/surround sound , so you get blast if you just switch over withor readjust the volume -- weird . - wire into the subwoofer be permanent , unlike the connection for the other five speaker . not a big deal , but you 'll have to cut and splice if you want to use you own speaker cable . - optical cable should have be include . they give you a digital coax , but why not the optical cord ? - pay special attention to the part number on the back of the five speaker -- they determine the proper left\/right\/front \/ back placement -- I miss this when I first set up the system - I be have some trouble configure my Hughes TiVo remote to control the ht-ddw660 -- the recommend TiVo code do not work . Time to get a $ 200 universal remote , I guess ... as I say , all of these be minor complaint -- in general , I be extremely pleased with the sound quality . I keep have to remind myself that I spend less than $ 200 for this great system . highly recommend .
