I had the 5000ES for about a month before it died. Managed to return it to the dealer who let me get the Pioneer Elite 56TXi. Immediately, I missed the sound quality of the Sony, which sounded closer to my old AKSA amps, very good detail. The 56TXi lacked emotion, detail, wonderful setup features, very easy to use. I sent it back and managed to get a full cash refund. Luckly, I was able to snag the new STR-DA7100ES for the same price as the 56TXi. I have been happy ever since. In fact, I sold my Hypex UcD400 amps (had 6 channels) to buy the Sony XBR 40" Bravia LCD. Perhaps, having the receiver is not as sexy but my kids all know how to use the system and we use it regularly.
The STR-DA7100ES is worth the upgrade and you can get very good deals now. I chose not to get the DVP-NS9100ES although the iLINK would provide the best connection (low noise floor and all that good stuff) but my darn Oppo DVD player works so well (even without mods). The video quality of the Oppo is hard to beat. And I end up using the Squeezebox to listen to music most of the time.
Keep it simple,
