does your Bose have m-ch analog ins? Even if it did, I highly doubt you will gain any improvement with lossless thru a Bose system.
if it only has SPDIF/optical, no mch analogs, then the 35 version is all you need. you will enjoy legacy dolby and core dts tracks. you will not enjoy mch uncompressed pcm track, but 2.0 pcm via optical. panny is good because it can translate pcm into dolby/dts, so you will always have some sort of surround.
My question is which of the above listed Blu- Ray players would best fit into my current home theater system? I have a Mitsubishi 46" TV (Model # WT-46809), which is about 7 years old, and a Bose Lifestyle 12-Series II home audio system, also about 7 years old, both of which I'm very happy with; I subscribe to Dish Network and have their newest HD-DVR model VP722DVR satellite reciever.The HD video that I get from the TV is in 1080i format for satellite TV viewing and 480p for any DVD's that I view with my existing DVD player. I plan to either replace my current JVC combo VCR/DVD recorder (Model DR-MV1S) with one of the above listed Panasonic models, or, I might decide to add on whichever one would you would deem to be the best addition to my home theater system. FYI- neither the TV nor the Bose system have HDMI inputs. I thank you in advance for any suggestions you may have.
