ok i am seriously tired of all the people complaining about hdmi passthrough. fyi almost every receiver developed before august of this year will not be able to decode DTS. Second there is no fuking difference that your ears will hear between DTS and the uncompressed Dolby sound, so if you rate this system which is a great value and has quality for a family home theater, a 2 then you are an idiot that tunnel visions. Audio codecs will naturally change as the amount of data being traveled through cables increases but the amount of data ur empty head processes will not change. Onkyo is a great for the value and has great quality for any home that does not need the absolute best(sound can get expensive quickly).
