I am trying to decide between these units, and I really need the help of members of this forum. Here is what I would like to know. 1-Is either one more powerful than the other. Do these receivers have powerful amps? 2-What is the sound like? Is it warm, bright, or neutral? 3-I currently have a Sony HT-DDW840 HTIB would this be a big jump in power and sound? P.S. I will be getting new speakers. Medium Size not Large. 4-Is the music that bad on the Pioneer. I am happy with the sound on my current system will it at least be as good? 5-I know the VR-6060 is the same as the VR-6070 does the THX features make that big of a difference in sound quality. Note I do not have any THX certified Cables, Equipment, or a room that meets specs. I just want to say thank you for your help in this matter. I am really caught up and need some good advice. Very tough decision to make.
