I am not familar with the gear you got now but I can say speakers typically give you the most bang when it comes to upgrading soundwise.
both those recievers have a lot of fans here although I do not own either. I myself have a HK 435 and I am very happy with it. Online from an authorized dealer its not much more than the 1015. You can even go refurb and save yourself a little more money.
The Panasonic for me didnt have enough optical inputs for me to invest in it. I didnt go any farther than the inputs when I was looking.
