I have two of these . one be a model that be no longer availible and the other be the current model . I boughtthe first to replace a sony rack system that i have for about ten year . I would still be usee it if lighting have not burn it beyond repair . I try many through a rental company and find that thy do not meet the quality that i have become acustome to . when I find this system , it once again make I ask the question , be that dog bark outside or on the tv ? the only thing that i have a complant about be that I have a dvd and sit PVR and both have digital audio out . the older version only have the one in with the choice of either optical or coaxial . this one have they seperate between video 2 and video 3 . I love it now . I still use they both .
