John

John,

did you do the Multimedia update? I just bought a Lexar 4GB USB memory stick and tried with both my iMac and a Windows laptop to copy the file, which I did successfully, and then to try the update but my receiver fails to identify any USB device?????? It is formatted as a FAT32 removable drive and automatically loads on my desktop (iMac) or in the Windows Explorer folder. File I copied is "Mrx_700_500_fw_upd.bin" and is 10.5MB in size. Have powered it down, then on... set it to media/USB but it makes no difference. Front or back USB input --- neither recognises the Memory Stick.

Any ideas?

Thanks in advance.

Cheers.

Using MRX dacs with or without ARC is all about digital concept (DSP).

Two completely different approaches. This is why some people with say the OPPO SE might lament their MRX purchase for music. You can always buy a cheap yet quality preamp such as Emotiva USP with HT bypass and have the best of both worlds.

Yes, but what I'm saying is that there probably is not a big difference between a signal using the MRX dacs without ARC and using Stereo mode (or something like that) and a signal going Direct pass through.

If the case is Purist vs ARC, I would believe that the room is too great a variable to ignore, and that having some sort of DSP, ARC being one of the best, to "correct" the room is far more important than a faithful signal in a "non-corrected" room, as your "faithful" signal will not be so faithful anymore once it gets to interact with your room!

Remember that it's not about the process, but about the end result!

Yes I have done it with no problem. Also use it for my oppo BD 83 updates. Try putting the bin file on the drive but not in a folder. Perhaps it will be recognized this way.

Okay, bizarre. It is in the root folder. H/W the output from Terminal on my Apple machine.

Note also that I was avocating a 'digital purist' line : if you must be in digital domain for ARC anyway, go with the digital out from your CD player, don't add DAC + ADC to the chain before the digital hits the ARC. You are adding noise and distorsion (however low it may be) to the digital stream unnecessarily. The only issue to worry about if you go digital is jitter, hence my question on the jitter rejection ability of the MRX DACs (with both SPDIF and HDMI sources). If you prefer using your CD's DAC, what that means is that it adds a coloration ('sound') that you are used to and you subjectively percieve it as 'better'. Objectively it cannot be better because DAC+ADC will change the bits - the result will not be 'bit perfect' compared to what is coming from your digital out.

Just re-did my Oppo BDP-83 firmware update with the same USB Memory Stick and it worked like a charm.

Something is definitely wrong with how I am putting the files on the memory stick or my MRX 500 is in need of repairs :-(

Cheers.

There is some truth in your statements. However, ARC is not a magic spell. I would be willing to bet a very respectable to high end 2 ch analog rig will outperform an mrx receiver with arc. This isn't a knock either. I want one. Lets just compare apples to apples.

This would be the case if your room was in no need of much correction, clearly not the case with most of the charts I've seen on this thread or the pre/pro one. I doubt any 2ch rig could compensate for bad acoustics, something ARC has been shown to do repeatedly.

64 bit windows vista OS and of course there is no serial port on my computer and of course I can't find a 64 bit serial usb adapter unless I go online and order one which will take a week here in Canada.

What a pain in the ass

What do you mean by 64 bit adapter? The Keyspan works with any version just the driver must be a 64 bit version. Keyspan website has those drivers.

Bring your reciever over to my place and you can use my adapter ! (I'm anxiously waiting for my reciever to come in)

I can't find a keyspan in a local store, they are only online and that takes days to order.

It would be nice if the damn receiver was USB

Noxdowne,

You can purchase the Keyspan locally at Memory Express. And, don't forget to get them to price match toners.ca. That will save you an extra 22 bucks.

Btw, ME is located in Edmonton, on the corner of Gateway Blvd and 34 Avenue. A short drive for you, but worth it I think.

I just listened to an MRX-700 today at my local shop. Sounded generally good, although they had just received it and didn't have it hooked up in a way where I could compare it directly to another receiver.

One interesting thing was that I was listening to CDs played via the new Arcam Blu Ray player, which was connected by both HDMI (BDP input), with the Anthem doing the decoding and D/A conversion, and analog RCAs (AUX input), with the Arcam doing the decoding and D/A conversion. I was surprised at how big a difference there was between the two when I switched back and forth. To my ears, the Arcam sounded much better - particularly in the low end. The Anthem processing sounded comparatively thin and bright to me. This wasn't so bad when hooked up to Paradigm speakers (which I found a bit boomy), but it was not desirable when hooked up to the type of Linn speakers that I own. This concerns me a bit because I just bought the new Oppo BDP-93 (no SE version yet) since I am counting on my receiver doing all of the D/A conversion. Is everyone else satisfied with the DACs?

I've been trying to add Anthem to the list of Keyspan distributors for a very long time and all the reasons that prevented it from happening are gone.

We just received a large quantity of the adapters and it's about to go in our catalog so Anthem dealers can order from us. I'm going on a bit of a limb here because it's not officially a product yet but if you'd like to order from tech@anthemav.com it's $30 plus shipping, and tax where applicable. The USD/CAD is at par these days so I suppose the price works for either currency, for now at least. If you can get it locally for the toners.ca price without shipping (and delivery time) then you might as well - regular shipping would be around $8 which negates the difference.

Pre-out frequency response is ruler flat (with ARC off of course) so was one louder than the other? I don't know what the player's frequency response is but can't imagine a CDP's not being flat, at least anywhere but at the highest frequencies.

If levels aren't matched to within 0.1 dB in a listening comparison the louder one always has an advantage. In the industry it's well known that an overall level difference of 0.3 dB, even 0.2 dB, is detectable by ear and can cause the louder one to sound "better", all else being equal.

Electronic volume controls in consumer products almost never have steps finer than 0.5 dB so analog trim is normally used to set up blind listening tests.

If your dealer had just received its' new MRX, it may be that ARC had not yet been run and uploaded, and/or that no separate Movie and Music settings were in place And/Or, that Dolby Volume was turned on for one setting and not the other. I have a Cambridge Audio 840C cd player and an Oppo BDP83 with Genesis Advanced Technology 6.1 speakers and I fine my listening results via analog and digital via HDMI and digital coax to be the exact opposite of yours. My preference is digital coax with the Anthem doing the D/A conversion.

I find the analog section of the Anthem to be lacking, but I purchased the MRX700 for its digital processing onlyl. Personally, I made the decision long ago to go to a completely separate analog setup in a different listening room. My analog room is always changing as finding true analog nirvana is and has been so much fun. That is what my loft listening room is for. Now, with the Anthem MRX700 in place in my HT room, I can leave the audio components in my HT/digital room alone (at least until the MRX900 comes out in a year or so).

Has anyone plugged an iPod into the front or back USB inputs? Using a standard Apple USB-line out dock cable? And got it to work?

I am trying to isolate my USB problems and I plugged in my iPod yesterday after I couldn't get the MRX 500 to acknowledge I had plugged in the USB memory stick to do the multimedia update. It didn't recognise the iPod either.

Any information/confirmation greatly appreciated.

Thanks in advance. Cheers.

Hey John,

So are you saying that the iPod Touch doesn't work with the MRX 500? Everything is leading me to believe my USB system on the MRX 500 is faulty given nothing seems to work with it? e.g. USB memory stick that is immediately identified by a Windows XP laptop or my Apple iMac or my Oppo BDP-83. I will borrow one of my kid's iPod Nanos and see if that works then. Can't try it til 5PM.

Appreciate the reply. Cheers.

Tony

How does one turn ARC processing on and off? I looked through every menu and option and could not find it anywhere. I could have sworn I saw it once, but I can't find it again.

My recollection is that you go into Setup and then into Advanced Source Setup and for each Source you can turn ARC on or off. And, if jayray were to respond before me, John would say: "why would you want to turn ARC off?"

Talking about comparing, now that I have my own MRX700 (& still have the Denon 4810), I do intend to do some more direct comparisons this weekend. Good thing that I have simplified my equipment rack.

Hey Folks,

Trying to get set up now... I see that the included disc has ARC v3.0, but the website shows v3.01 as the latest. Is there a difference?



EDIT:

Nevermind... It appears to be the same version.

Yes. From the change notes in the ARC V3.0.1 download:

Quote:
v3.0.1

1. Fix for quick measure crash caused by starting measurement then disconnecting mic then clicking "disconnect" or the "X".

2. When multiple cal files are present, popup that lists them goes to foreground instead of background.

I can't say for sure whether the levels were perfectly matched. My perception was that the volume was the same. The Anthem just sounded like it was emphasizing the top end much more and was thinner in the bass, giving a less rich sound overall. It's possible that this had to do with the different settings for AUX and BDP inputs. Like I said, they had just received the unit and hadn't finished tweaking it. That's why I'm interested in other people's opinions about the DACs.
