Strda3700es
The STR-DA3700ES receiver comes with a 3 year parts AND labor warranty. On top of that there appears to also be a special 90 day program where they will swap out an unsatisfactory unit and replace it with a new one should you have a problem.
I think there have been some great Sony receivers over the years. The hard part is knowing which one is going to be the good one. The 3700ES has a lot of features related to usability and programming. When you think about where the receiver concept got started, it sure seems like we've come a long long way from the days of those two channel Pioneers and Sansui's.
For the DA3700ES, I believe it sounds superb. I'm not concerned about it having twitchy hardware. It has a great warranty.
I am worried about its software. Out of the box I went ahead an upgraded the firmware on my unit to version 966 per the startup instructions. I must say that getting all of the pertinent networking applications enabled and running was a bit tedious. Even so, I have my doubts that a person lacking significant technical aptitude or experience would find this receiver to be at all easy to get fully operational. On the other hand, it does a lot more than play the radio. I think is one issue is that different applications (Pandora, Netflix, etc) have different ways that you must enter your account information or otherwise enable the application. To even see the available applications you first have to download them over the internet. There is just a lot of steps. Experience with networked appliances helps.
Once enabled, some applications do not boot up reliably (Pandora). Some (Slacker) do not run reliably. Some seem to work OK once setup (Netflix).
I expect that the software will become smoother over time. As Sony is a content provider of sorts, it is in their interest to make sure it does. As is, it certainly is acceptable even with the occasional glitches.
The DA3700ES is less of a receiver and more of a computer system albeit diskless. It runs on a Unix operating system, has advanced graphics, needs a monitor to run, is networked, and has significant non-volitile storage. Like I said, these units have come a long way since 1978

My next project with this one is to tie it to a DNLA server (preferably a movie box of some kind - not a PC). I like the promise of DNLA and would be curious to know what successes folks here have had with it.
