I am going to be heading to the store for a first time purchase of a home theater system. The manager of CC was trying to sell me on the Onkyo TX-SR500 for an unbelievable personal friends price ($230.00). After looking at several post concerning this Onkyo model and have read that a lot of people are having trouble with the subwoofer not responding properly, I am now unsure of what I should do. The other option that I have explored is to purchase a Panasonic SA-HE100 at another unbelievable price for this system. I am asking if anyone has had any negative feedback on the Panasonic SA-HE100 that I should know about. I am also welcoming any suggestions about my up and coming purchase of my new home theater system! Thank to all how can contribute any wisdom and experience.
