The best sound came from the Analog-Direct, 2-channel with no processing. The second best was the re-digitized analog set up (Bob's choice #3 ). Last came the mode using HDMI in which the music felt shallow compared to the deeper sound of the other two analog-fed modes.

So my conclusion is that it is best to listen to the DSD analog outputs of the Oppo when listening to SACDs even if I plan to use ARC (which requires re-digitizing).
A suggestion: For the best comparison of the processed, Stereo Analog (and HDMI) choices here you should set the Audio Surround mode in the D2 to STEREO, not to Anthem Logic - Music. That will produce sound on the Left Front / Right Front and Subwoofer only. Press Mode and use the Arrow keys to cycle through the choices -- or set Stereo as the default choice for 2 channel input in Setup > Mode Presets for that Source line.

I.e., engage ARC processing but do NOT also engage Anthem Logic - Music surround sound processing (which converts Stereo input to more speakers output).

For the processed Analog case (Stereo Analog input re-digitized so as to allow ARC processing), also be sure to check your setting for how the D2 does that re-digitizing. See Section 3.9 of the Manual. By default, the D2 re-digitizes Stereo Analog input at 44.1KHz. Raise that to 96KHz. This is particularly important when the Source material is recorded at a higher sample rate to begin with -- as with SACD. (The Multi-channel Analog input already re-digitizes at 96KHz by default.)

Thank you for reporting your testing. I have been espousing this for a long time and now another forum member has confirmed what I hear. Though this does not hold true for videos played on a home theater.In that case HDMI to the Anthem with multichannel DTS HD Master or Dolby True HD lossless formats using ARC are the best formats.

Thanks Bob! Following up on your suggestions, I have confirmed that the D2 was already set to process all 2.0 signals at 96 kHz.

I listened to an SACD (DSD) orchestral recording using the following four settings:

A) PCM Stereo (HDMI input, Stereo 2.1 channels output)

B) 2-channel Analog Direct (Analog-Direct input, Stereo 2.0 channels output, no ARC)

C) 2.1 channel from Analog source (AnlDSP input, Stereo 2.1 channels output, ARC Processing of analog 2-channel signal coming from Oppo 105D), and, just to relate to my previous listening test,

D) 4.1 channel derived from analog source (AnlDSP input, 4.1 channels output, AnthemLogic-Music mode, ARC Processing of analog 2-channel signal coming from Oppo 105D).

Here is how I ranked them:

1st. 2-Channel Analog Direct, no processing. The sound was much more engaging and musical than any of the other settings.

2nd 4.1 Channel Analog (AnthemLogic-Music, AnlDSP coming from Oppo 105D’s 2-channel analog). This setting was closer to the 2-channel set up than any of the others.

3rd 2.1 channel Analog (Stereo 2.1 channels, AnlDSP, coming from Oppo 105D’s 2-channel analog).

4th PCM Stereo (Stereo 2.1 channels, HDMI input). This setting lacked bass, not a deep or wide soundstage, in fact, the music was not very engaging.

My conclusions from this test are the following:
· The analog output from DSD sources provides better sound than digital PCM even though the analog DSD requires reconverting to digital (i.e., double processing).
· The quality of the DACs in the Oppo is superior to those in the D2. That should be expected though, because the DACs in the D2 are already aging technology, meanwhile, the Oppo uses some of the best DAC technology of today.
· ARC is doing its job, but it cannot make up for the aging DAC technology inside the D2. The 4.1 AnthemLogic-Music mode sounded better and fuller than the 2.1 Stereo when using the same analog source. With 2 extra speakers to work with, ARC is able to do a better job.

I love my D2, but it is obvious that it has not kept up with the times. The D2V is also an old by A/V processor by the standards of the times. I am still hoping that Anthem has a strong replacement of their flagship unit coming VERY soon (hint: a good showing at CES this January for example). Hope is the last thing that dies…

Anthem D2/D2v/AVM50/AVM50v/ARC1 tweaking guide

I don't think the DACs are entirely to blame. The D2v and 50v have better digital input clocking circuits, and they sound quite a bit better. I believe final DAC stage is the same as their earlier versions (50v lacks up-sampling).

With your 2nd favourite choice, the DACs are in use but not the digital input.

Is there a pre-pro out there that would be an excellent or even superior alternative to the D2v in sound and video?

Almost a dead area for manufacturers I believe.
The closet thing out there would be an OPPO 105D except it does not have multi port HDMI switching or 4K.
There are some really high end pre pros but they lack also 4k and 3D such as Datasat and McIntosh

^ "Two" is still, technically, "multi".

The main disadvantage of the OPPO 105D as a pre-pro is that neither of those two HDMI inputs can accept 3D (or 4K), or Bitstreams for Dolby TrueHD or DTS-HD MA, or DSD. Of course you can play shiny discs or play media files on an attached drive -- or over your house network.

So you have to deprecate HDMI input as the fundamental -- must do "everything" -- input.

Wait, maybe that's a GOOD THING!

^ All audio processing other than Volume is done in the digital domain. So yes, no Tone control if you are using Analog-Direct to avoid re-digitizing an Analog input.

Right, I'm not about to jump ship, but it could be an option for some with well behaved rooms. As you can see from the review (Secrets Best of 2014) and reader comments there are different schools of thought on the merits of RC / room EQ.

Excellent Anthem D2v 3D review at secrets http://www.hometheaterhifi.com/proce...or-review.html


It was bench tested like crazy and here is part of the technical summary...




1. Anthem Direct is the cleanest lowest possible distortion path, especially using XLR inputs and outputs with distortions much less than 0.001% .


2. HDMI inputs to XLR outputs had distortions of 0.002% or so regardless of sampling rate (44.1kHz to 192kHz)


3. The audio platform is 10 years old(same as Anthem D1 that came out in 2004) yet still kicking and producing excellent sound and technical specs.


4. Frequency response in Analog Direct is about 90kHz. With Analog-DSP, with ARC engaged, the frequency response is 48kHz and it crazy drops like a stone after that value.


5. Frequency response in HDMI (ARC or no ARC) was not measured, unfortunately.


Review summary... "The sound is reference quality with excellent detail and a wonderfully silent noise floor."






David.

Any word on when Anthem will be able to address the desire for Atmos capability?

You have to hand it to Venus de Milo..., otherwise she would starve.

Computers have abundant memory, but no imagination.

I am playing an Atoms Movie on my D2 - The Movie is
Expendables 3 - my Sony S790 is converting the Atoms
to LPCM for my D2.

It is the BEST SOUND I HAVE EVER HEARD for a Movie.

For many years with my D2, I used your #3 (2-ch analog with ARC) with paradigm Ref sub and my system sounded really good. In the past 8 months when I got my S8V3, I decided to compare #1 (analog direct, no sub, no ARC) with #3 , and never went back to #3 . My CD player is a Marantz SA11S2. Like you said, sound was much more musical and engaging. Now, I only use ARC for movies which seamlessly integrates my Ref sub to my speakers.
