Marantz AV7005 - Page 102

Your reply is one of the exact reasons I hang out in a place like this :-)
I'd be very interested to know how you prioritized the network traffic and the subsets of which you determined work best.

Initially, I felt kind of good when I finally got Rhapsody to work after fighting with the wireless bridge to only then not be able to reconnect the rhapsody.

Thanks for your hard earned knowledge on this topic.

My internet router is a Cisco 871. So, it's a little more full featured than most Linksys, DLink, and Netgear hardware out there. You can pick them up on the big auction site pretty cheaply now, since they're a couple generations outdated.

With the help of this site, in one of the Denon receiver forums, I determined that Rhapsody has two parts. The front end portion with the authentication, search, and menu functionality is served directly by servers in Arizona (as you noted in your original message, this part works everytime) and the music stream itself is served by a company named Limelight in New Jersey (at least that's where the IP addresses trace back to). So, I prioritize any traffic coming through my router from the Limelight subnet ( 208.111.168.0 ) as a DSCP of ef (express forward). This made it a little better, it probably works 2 out of 4 times that I try Rhapsody. And, that's still worth it to me because I enjoy the availability of content on the Rhapsody service so much.

I don't want to overstate my results with Rhapsody, it still isn't worth anything more than an interesting networking experiment. When I got home from work today, my wife had tried to use Rhapsody on the AV7005 and it had locked up on her. She didn't know the full reset trick I mentioned in my last post. I'm here to tell you, nothing makes it harder to get wife support for ongoing A/V purchases than having it stop playing while she's on the treadmill. I've since shown her how to play Toby Keith from the Media Player on her laptop and she's back in my camp.

As I mentioned before uPNP media players and Airplay seem to work fine. You will ocassionally get a lockup and have to reset all of the zones in order to get the NET/USB source to respond again. But, the lock ups happen a fraction of the time compared to Rhapsody.

Good luck! Ben

Thanks!

I have the same issue with the network feature on the AV7005. Plus, when checking for the firmware update it gives me a "Connection Failed" message. When going into Maintenance Mode the "Web Access Port" is [10443] and I get a message saying "Port Open Error - Could not open port". Did you have similar experiences with this?

-Single circuit. Coax direct into cable box. No cable power connected. Nearly inaudible hum from center channel and even less audible from tweeters of L&R fronts.
-Single circuit. Coax direct into cable box. Cable power into power center.
Nearly inaudible hum from center channel and even less audible from tweeters of L&R fronts. No change.
-Single circuit. Coax into power center. Cable power into power center.
Nearly inaudible hum from center channel and even less audible from tweeters of L&R fronts.

Contrary to what I posted yesterday. The only thing that made a difference is the single circuit tonight.

BTW, in the single circuit cases the hum is so faint I need to put my ears right up against the tweeters. Less than a foot from the grills.




Single circuit.

dunno. falls into the "don't care" category for me.

2. Toroidal or EI core transformer - All Marantz documentation says EI core, Marantz customer service says it is EI core but perhaps they simply referred to the documentation. Existing pictures show toroidal so it was suggested that it was just a round shaped shield/cover, but one poster found that hard to believe.

dunno. again, falls underneath "don't care".

3. The issue of being unable to run Audyssey MultiEqXT when decoding HD codecs at >96 kHz. This apparently is confirmed to be true according to the manual of the manual on the Outlaw site.

yup, that would appear to be true, iirc

4. Some claimed that the AV7005 may be more prone to hum and buzz issues.

that would seem to be true. i've been fortunate enough to not run into this

5. The XLR balanced I/Os are just balanced I/Os but not the internal circuitry. This may be true but who has seen the circuit diagrams?

that would also appear to be true.

6. Some claimed that the SR7005 is based on the lower priced Denon AVR3311 that has fewer features, and that the AV7005 is based on the SR7005 less the amp section plus perhaps with some better quality components.

i would be completely shocked if this wasn't true, with enough "differences" (possibly "quality related", but likely "just different") to make the marketing people happy


The following are 100% clear to me:

7. The extra channels, height and wide cannot be on simultaneously, you have to choose one of them, or the surround back.

yes.

8. Audyssey MultiEQ XT only, not XT32 that is found on the Denon AVR4311.

yes.

9. Most, if not all users so far are happy with the AV7005's sound quality.

yes, in that it does nothing "bad" to the "sound", and doesn't sound any "different" from previous units i've owned

10. Some owners thought the AV7005 sounds better than their previously owned AV8003, Integra DTR 9.8, Denon AVR-4810 etc.

see #9

11. One user (at least one that I remember anyway) thought his Onkyo or Integra(not sure, forgot the model) was better sounding.

So it seems to me the AV7005 may not have the perceived higher end parts and components that some of the comparable Onkyo, Integra, Denon prepro/or AVR models have, but most users are impressed with its sound quality and the good look.

Haven't figured mine out yet (thankfully it's not bothersome after I removed the splitter from the coax cable but still want to try and nip it), though some are suggesting to eliminate the ground pin on the XLRs.

BTW, try unplugging all of your HDMI cables, let me know if the hum entirely disappears.

To be clear, my hum issue was, I've demonstrated, due to a poor power circuit implementation: multiple ground paths. Once I fixed that the hum issues are 99.99999% gone. (Note to self find out what a noise floor from an amp is.)


At present the only hum I'm getting is from the tweeter sections only and is so faint I have to put my ear up against the speaker and listen for it. Ya' know.... I can live with that.
