Hello all! I recently picked up a Sony Bravia 46". I would like to add some addition speakers to it to enhance the sound of both TV and digital music channels (which I will son be subscribing to). I already have a DVD player and several good speakers, so I really don't need a HTIB system. What's the best, most cost effective way to do this? Can I just buy an inexpensive receiver? My old TV had inputs for extra speakers. Thanks. I appreciate it.
