Well, Here's the plan I have: I am thinking about getting the Onkyo TXD900. IT powers 230 watts by 7. IT has Thx Ultra Certification. And it has PC to MP3 playback support. MY worry is, that I heard the software included with the Onkyo is not very good when running MP3s. I also am concerned that I won't have the Logic 7 included with the Harmon Kardon AV8000, which I am also considering. Any input from you guys?
