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

The signal being output by the TV will be Dolby Digital stereo or surround depending on the broadcast

It depends on TV. Panasonics output Dolby with digital and PCM with NTSC automatically. Since NTSC is gone you would be stuck with Dolby. There is no menu to switch it (unless newest TVs have it). Samsungs have it selectable in the menu. Better check it before you buy. I have Samsung LED connected to two channel DAC.

Does your cable box have a digital audio out?

Yes .. the current comcast box i have has a digital out.

seems like the good news is there no need to purchase a new pre-amp since my old one should work

thanks for the help
now just need to come up with the money for a new panasonic plasma
