I am about to take the plunge into a new AV system. I have somewhat decided to buy a panny 6 plasma, but am unsure whether there is a need to have the 600 tuner as well, since the only advantage that I can see is that it will allow a single cable connection. My intention is to mount the panny on the wall above my fireplace, since I do not think there is a heat issue (thermometer checked), so having 1 single cable would be an distinct advantage. The panny will replace my current CRT TV, and also intend to get a DVD either recorder or player and new speakers, but the remaining equipment that I have I would like to keep and integrate into the new system. I have a Panasonic sky digibox, a Sony SLV-SF90 Video, and a Sony MHC-NX3AV hifi. I am a bit baffled by the use of amps and receivers, and integrating my existing equipment into the system. My existing hifi only has an output for the 5.1 speakers, and no output for connection to a separate amp. The hifi can accept inputs from DVD, and also TV tuner, which I think would allow me to connect these through my existing hifi. However, I do not want the home cinema experience to be reduced through using my existing hifi. Similarly, I do not want to have two sets of speaker (1 for home cinema and 1 for hifi). Anyone got any advice on how to integrate or whether I should ditch the existing hifi into another room and play the cds through a DVD ??
