Anthem MRX 500 vs Denon AVR 2311CI

post #1 of 17
Thread Starter 
I am a newbie when it comes to home theater and hi-fi audio systems, so pardon me if I am missing some basic information. I have an 18 X 20 feet family room which is open to other areas of the house on 1 side. Last month I bought 2 Paradigm Studio 100 speakers with a CC 590 center channel. I am planning to get Paradigm Sub 12 or SVS PB-13 ultra sub and 2 Studio 10 speakers for surrounds, later next year. My end goal is to setup a home theater system to listen to music and watch movies and tv.

Since last 1 month, I only have front 3 speakers hooked up to the Denon AVR-2311CI. I really love the sound of Multi Channel Music from the AVR-2311CI, it’s not too bright and not too tame either

Yesterday I bought Anthem MRX 500 with very high hopes of getting even better quality based on recommendations from various sources but the predicament I am in is that both me and my wife didn’t like the music from MRX 500 better than the Denon AVR-2311CI. We thought the sound was less crisp and much warmer (being new to this I am not sure how to say it was good or bad). So far we have not watched any movies on either of the system as 65 to 70% of our need is music and I heard that if a system is good at music it should be equally good with movies (correct me if I am wrong). I really wanted to like the MRX 500 and even used ARC to perform room correction but still the out of box settings of Denon without any room correction or anything is impressing us much more than the Anthem receiver. So please advise upon what to expect from each receiver and why is one better than other and how to properly compare the 2 receivers to select one to keep.

Update:-
After talking to my dealer today, I switched off the Dolby feature of MRX 500 from the setup menu and wow, now I can see what real Anthem power is, the performance/power is amazing from Anthem MRX 500 now. Only issue still left which I didn't mention before is that, there is considerable static noise coming from all 3 speakers’ tweeters with MRX 500, when I connect it using HDMI 1.4a to my Sony vaio laptop, to listen music from ITunes. Same is the case when I connect PS3 to MRX 500, using HDMI. I have tried using different HDMI 1.4a to rule out if my HDMI has some problem.

Although a very minute static noise is also present in all 3 speakers’ tweeters, when I use Denon receiver instead of Anthem receiver but still the noise in Anthem's case is too much and really messing up the songs, whereas this noise in Denon's case is not messing up the songs at all. Also the noise is only coming from the Tweeters of all 3 speakers (i.e. Front Left, Right and Center Channel). Please let me know if you have any ideas what may be the reason and how to fix it?

Many thanks for your time.

Really in the end it comes down to what sound you prefer. Some like "warmer" sounding speakers/amps, while some prefer brighter. Whatever sounds best to you is what's important.

I have the MRX-500 and on all HDMI sources, internet radio (When it actually works with out freezing up or cutting out), I get a static low level noise almost sounds as if there is a cold solder joint in one of the circuit boards. It is only in the center channel speaker the other 5 speakers are fine! Doesn't matter if Dolby vol is on or off, ARC on or off. The volume control setting does not effect the static either. I even hear it when I turn the mute switch on !! I have already done all the upgrades to the software so that is not it either. Anybody have ANY ideas?? I emailed service at Anthem but they were no help either.....

One good thing was that I discovered how much better the music was with the Evil Dolby Volume OFF! Wow! Dolby Vol really sucks!

shenzhen dude,

Did you ever get a resolution to the noise problem in your MRX?

I was able to get a work around by resetting the MRX 500 to factory default settings. Although i still get the static noise but after reset its not messing up the music, i guess i ran the ARC incorrectly which caused it to mess up the music.

I talked to my dealer and he said i will have to live with the static as there is no solution to it. Plus i don't care much if the music is not being affected (atleast to my ears).

My first unit I got static in the surround left speaker. It actually got quite loud. A gurgling static noise.

Now with my second unit I started noticing a sizzling static noise in the left channel of my headphones. Well, you bet, without the headphones I'm getting a sizzling static noise out my left front speaker.

how can a dealer say that "static" is something you have to live with ?

it sounds like a hardware fault (that others have had as well I think) - and should be fixed ?

edit I see you got same with Denon as well as the Anthem static wise - so must be your source so I take back what I said about the Anthem

Not for me.

Only the Anthem MRX 700's.

I just tried everything.

Swapping speaker wires, unplugging...HDMI, ethernet, radio antenna, speaker wires (all of them), sub line out.

Plugging it into another outlet across the room.

Unplugging the TiVo, ethernet switch....

I had a gurgling noise in the left surround from my first Anthem MRX 700.

Now I have a growing "sizzling" static noise coming out my Left front on my second unit. It's gotten so loud I can hear it while watching/listening to TV with the headphones on. THAT'S how I first noticed it, noise coming from the left channel of my headphones.

NOT ready for prime time.

dean-I - I think some on uk AVF forums had similar - had unit replaced and has not returned

I can't fathom what would make static type noises - that that would go faulty to create that sort of fault mode

What makes me nervous, is that they don't do this when you first get them.

Then a week later ONE of the channels starts making noise.

I'm not sure what firmware you have but I have firmware 50.12 and there is absolutely no static in any of the speakers. Having static is definitely not normal. I've had my unit since Dec/11 and use it almost everyday.

It's highly unlikely that static in one channel would be a firmware issue.

Seems like Anthem has a batch of defective amplifier boards, either because the boards were assembled poorly (e.g. bad solder joints), or they have some marginal components (e.g. failing capacitors). Such static would absolutely be cause for warranty replacement.

Keep in mind DV has two parts: a "modeler" and a "leveler."

The "modeler" is a DSP loudness compensation, similar to Audyssey DynamicEQ. I find it very useful for music, because I often listen at lower levels.

The "leveler" is a compressor, similar to Audyssey Dynamic Volume. Best tossed aside, IMO. It sucks the life out of things.

Those with static I thought also had it with headphone out ? So perhaps before amp stage

It is odd though

OK, so it's probably not in the amp stage, but in the preamp stage. Still, it's highly unlikely that a firmware issue would cause static in just one channel.

Might be worth upgrading to eliminate the firmware as the cause?
