do i still need a pre-amp

time to upgrade my older pioneer elite rear projection tv to a plasma. everything now requires HDMI so my old rotel pre-amp cannot be used.

i have aerial speakers, martin logan sub, rotel amp and a panasonic blue-ray player.

i only use this setup for tv and movie watching so i was thinking to save some money just using the source switching on the tv as a pre-amp.

any thoughts if this would cause a loss i sound quality or ??

thanks

What LoomisJohnson suggested will work provided that you have cable and that your cable box has analog outputs. If you are receiving your signal over the air and your TV is doing the decoding then the suggestion will not work.

Very few if any TVs today have analog audio outputs, only optical. The signal being output by the TV will be Dolby Digital stereo or surround depending on the broadcast. If this is your case, then you are going to need a processor with an optical input to convert the Dolby Digital Signal to analog stereo.

It sounds right to me. I guess that answers your question, you still need a preamp.
