Now this is going from laptop to oppo. If you're connecting hdmi from another source beside a laptop then I do not know. I just know that coming from a laptop using hdmi out to oppo sounds like shieet. USB DAC from laptop to oppo sounds amazing. It sounds even better than playing files directly from oppo front USB port. Playing FLAC files ripped directly from original retail CDs.


To give you guys my audio setup, here it is:

Sony Vaio SVS131290X, to USB DAC on Oppo 105, to McIntosh MC402, to Klipsch La Scala (no subwoofer needed, nothing in this world can match the quality of La Scala)


Windows 7, Oppo Drivers, Foobar, KS (kernel streaming) drivers output to Oppo USB DAC.

Something is wrong in your setup. There is no inherent reason for the audio on the HDMI inputs to sound bad. The most likely problem is in the way the Vaio is generating the HDMI output. That will take some detective work to sort out.

Also keep in mind that using the Asynchronous USB DAC Input bypasses the audio processing in the 105. For example, no Crossover processing. But when using the HDMI Inputs (or playing files from an attached drive) that audio processing is in effect. So if you have your audio processing settings poorly chosen in the OPPO that could make the audio on the HDMI Inputs sound bad. For example, make sure you have DTS Neo:6 Mode OFF unless you really want to use it at the moment.

There are plenty of people posting here using the HDMI Inputs for multi-channel audio (which the DAC input can not handle), and so far no complaints.

I have a similar reaction to your report that playing files from an attached USB drive produces poor sound. Again, something is wrong in your setup. It's great that the USB DAC Input is working so well for you, but it really is worth the time to figure out what's up with the other playback methods, because there is likely a simple error of some sort.

Wow 3 la scala in front. Must be real nice. Even if I want to I don't think I will have the room for a 3rd one.

For a long time I did not have room for three. Went with a projector and Seymore AT screen, all three are behind the screen. Screen's only effect on the sound is lower above 10,000 hertz down half to a dB, which for me was not possible to hear differnce doing A B A testing.

Beta firmware with 0 on delay resolves Lipsync issues with Uverse Motorola and does not affect Bluray. But twice in two days video stops and starts until a reset. Do not know if Beta firmware or Uverse is the root cause. Uverse wireless did lockup last night.

If I were you, I'll be looking into dumping the marantz and find a used dedicated amplifier. Then I would connect the oppo directly to the amp. I use my oppo as a pre-amp. You can probably get about $250 to $300 for your nr1602 on craigslist. Dump the marantz asap.


Thanks for your reply but I disagree with you.

I think PQ is important, speed of the user interface is very important and the Oppo seems to shine in these areas. I have been having a few minor audio issues with the BDP-105 + Sennheiser RS180 wireless headphone + band of brothers bluray combination. Audio seems to come in and out.. sort of unpredictable and sometimes I hear background audio but not that of the foreground.

I love the Marantz 1602. I got rid of the Denon 4806 CI recently and switched to the Marantz mainly because of its much smaller foot print, apple airplay and network features. I hated the Denon as it was looking like a beast in the living room. I also seriously downsized my home audio video equipment and the Marantz helped. I have this connected to NHT VT1.4 speakers and a VS2A center channel speaker and the AQ is pretty good.

What I need to figure out is.. how to connect the Marantz NR1602, Oppo BDP 105, LG 1080P plasma TV properly. I currently have the Marantz taking in the HDMI output from the Oppo but I think I should probably connect the Oppo directly to the TV and use the Marantz just for audio. Since I would be using the Marantz primarily for audio only, I also think (After reading some posts here and there) that I should connect the Oppo to the Marantz not via HDMI but some other means.. how?

Thanks for the reply.

Here is a picture of the chip I bought:
Processed By eBay with ImageMagick, R1.1.1.M2b

The picture shows it in a 103 but it is supposed to work in the 105 as well.
After removal of the top cover of my 105 I did not find a place to plug it in so I remove the board at the top left corner and still did not encounter an open plug.
That was as far as I felt comfortable taking it apart.

Was your chip easier to install and if so where did you obtain it?

post #4657 of 10065
I'm not sure which "top left corner" board you mean. It would depend on the orientation of the player. With the player's front facing you, you would need to remove the top board on the back right side of the player. This is the board that has jack inputs on the back of it. You don't really have to totally remove it, but only move it aside. I was able to do this without trouble. Others have found it easier to remove the entire board. Just be sure you remember how it is connected via the short cables to the boards below. Once you have this board out of the way, the board directly below it is identical to the one in the BDP-103 (since the video sections of both players are the same). That is where the connector should be that you connect to. Apparently some recent builds of the the BDP-10X models have changed this board and the connector the mod requires is no longer on the board and therefore this kit can't be used. It is possible you may have such a unit. In that case you would need the mod that connects externally. Do a search in the BDP-103 forum and you will find references to that kit.

Be careful when putting the (re)moved board back. One of the screw holes is a bit hard to get at and it is quite easy to drop the screw into the player and have it disappear under a board at the bottom. I know about this, because I did it. I was fortunately able to gently turn the player upside down and shake it lightly until the screw came loose and fell out. There was apparently no damage but I wouldn't want to chance it again.

Thank you Bob for your response. I tried this on another laptop the HP Probook 4730 and with same result. I don't know if it's in fact my HDMI inputs are defective but I highly doubt it because the chance both front and back ports are defective is shocking and very rare. Also, I do not want any additional or unnecessary audio processing to be done on the digital signal coming from the laptop. I want a pure digital signal going straight into the ESS DAC on the oppo and then spits it out and go straight to the amp. I dumped the Integra 80.2 that used to sit between the oppo bdp-95 and the amp when I bought the bdp-105 after I learned that there are digital inputs and also they fixed/improved the digital volume. I have 2 years for warranty so no rush with the repair if in fact both hdmi inputs are defective which I doubt. Bob, if you can, would you be able to test your hdmi inputs for me? Hook up just 2 channel into the dedicated stereo output (xlr or rca, don't matter) and test the hdmi inputs compare to the usb dac for 2 channel music only. You can just play a few songs and see if you can detect the thin sound like what I am experiencing? TIA.

Update: Bob, I think there's another possibility that your processor sits between the oppo and the amp could be doing some processing as well? That could be the reason why you cannot detect the difference the hdmi inputs and the usb dac. About the front usb port on the oppo, I did more testing and it sounds fine but on certain songs it is more harsh and more bright compares to the usb dac or the original CD playing from the tray of oppo. I really like the USB DAC output quality, crisp, pristine, clean sound.

Good news on the beta firmware and audiosync. I no longer have issues with audiosync using hdmi straight to TV and USB DAC to the oppo. Before this was almost un-watchable. Thank you oppo for getting this issue resolved. Watching movies on laptop like x264, xvid and youtube is a real pleasure with no audiosync issues. smile.gif

Some suggestions:

1. Get the special real time linux kernel for your Squeezebox touch and connect the touch to the USB input for the Oppo. This will be superior to using the analog outputs of the Squeezebox, which are rather mediocre.

2. How big a deal is room correction for you? If you don't use room correction:

Connect the FIOS box and Apple TV to the Oppo HDMI inputs

Connect the Oppo directly to the amp via the analog outputs. Use this for your zone 1. Connect the Oppo HDMI directly to the TV and the S/PDIF or other HDMI to the Marantz and use the Marantz for your zone 2 stuff.

-OR-

If you do you want room correction keep the AVR for zone 1 and connect the Oppo, FIOS box and Apple TV HDMI to the AVR.

With my brief time with the Cambridge unit (zero nanoseconds) it's difficult to form a solid opinion. But based on the specs and one review it seems to be close in caliber to the Oppo 105 with less features.

My guess is that the operational "guts" of the system are very similar to the 105 - Mytek, Qdeo, etc. And I wouldn't doubt that an open forum of posts regarding the unit would show similar problem issues as the 105 since the "guts" are provided mostly by the same third parties. As well as resolutions around the same time frame with firmware upgrades.

Main difference is the lack of certain features and their choice of DAC chips. I think the whole Anagram thing is a bit strange - why would you need an upsampler when your DAC chip does upsampling? Maybe the Wolfson chip has less features than the ESS chip. Even a modern $100 (or less) player does upsampling these days - it's standard technology. Can't say they all do 32bit@192kHz but I'm guessing even the least expensive toys upsample a CD to 24bit@96kHz. Heck, it's cheaper, sounds better, and is less expensive then building a proper analog filter.

If one had the time, and the access, a double blind listening experience between the two and some unknown universally accepted "reference" player might provide two pieces of information:
  1. which sounds closer to "reference"
  2. which one you like better

Just as someone might prefer a bit of EQ vs flat response so then may one or the other be more pleasing to a specific ear.

I haven't taken the time to adequately characterize the HDMI output of my Mac. (Apple has a long history of doing odd things on HDMI.)

But I *DO* know the characteristics of the OPPO BDP-93 player, and what my Anthem Statement D2v does with Analog audio input.

So what I did was compare two Sources:

1) OPPO BDP-93 HDMI 1 output, to Rear HDMI Input of the OPPO BDP-105, to Stereo Analog output.

2) Mac computer USB, to Asynchronous USB DAC Input of the OPPO BDP-105, to Stereo Analog output.

My Analog output of the 105 is set to use no audio processing in the 105, and thus I can directly compare the two inputs without having to account for the fact that the DAC input bypasses such processing.

My D2v is set to take the Analog input and produce 2.1 output (my speakers are intended to be supported by a Sub). No additional processing.

I compared one of my standard, evaluation CDs.

The two Source methods, played this way, sounded identically excellent. There was no deficit using the HDMI Input.

Now obviously this is just one disc, but still, there is no patent difference in quality of the type I think you are suggesting.

Perhaps you were exaggerating the difference, but if you were REALLY hearing a difference that dramatic then, again, there is something wrong in your setup. Since you've heard it from two different computers now, the next step is to double check the audio settings in your 105. I doubt your HDMI inputs are defective (hardware problems in those would not produce the type of difference you are reporting).

You have to understand that the LPCM from the HDMI Input (when playing the CD) *ALSO* goes straight to the DAC from the point where the HDMI input is buffered and re-clocked -- unless you've got something else enabled such as Crossover processing, speaker distance adjustment, speaker volume trims, or DTS Neo:6.

I also suggest you toggle the Audio Processing > Stereo Signal setting to the alternate setting and back to make sure you are not being bitten by that bug. The bug wouldn't affect the DAC input since it bypasses what that setting does.

I also posted this in the 105 Sound Quality thread.
I currently have a Oppo 103 connected via HDMI2 to an Integra DHC80.3. Do you think I will get any gains going to the 105 and feeding it analog, and if so, how much. FWIW I do not use Audyssey for music so no worry about another A to D and D to A conversion, it will stay analog. The 80.3 has Burr Brown 192/32 DACs.

Thanks ehlarson,
1) that seems logical and I understand that connection.

Also I'm not familiar with " room correction" if some could give me a brief explanation that would be great.
B) going this route, will the Apple TV also utilize the DAC in the oppo? Or do I need to make a additional connection?

One newbie question. If all my music is ripped from CD's(80%) ,iTunes (20%) will I still have significant improvement in SQ with the 105 vs the 103? ( after installing EDO).

Improvement over the 103 is all about using the analog outputs of the 105 directly to an amp or preamp. If you use a digital connection to your AVR you might as well buy the 103.

The USB output on the Squeezebox touch with the EDO kernel is a very nice transport. It really has a lot going for it. Nice user interface and stable data stream. Probably better than any computer USB output because it is dedicated to a single task.

I think you could use the AVR to power your multiroom.

Room correction is Audyssey.

By connecting the Apple TV to the Oppo, and the Oppo directly to your amp you would be using the Oppo DAC for the Apple TV sound.

YMMV, Many hear no difference but I do.

I use the BDP-105 connected to the Marantz AV8801 and I have setup my remote toggle between the HDMI, COAX, XLR, and 7.1 analog outs.
Only the 7.1 are not redigitized by the Marantz and I prefer the sound.

Perhaps the difference in experience has to do with the processors handling of LPCM over HDMI or related to your system or speakers.
Since I do not user room correction, I use the 7.1 excusively.

I do not think anyone can get you a definitive answer.
If it is not a financial burden and you must know, try one smile.gif

If you do exactly what I do that would be great. Just remove the anthem processor completely out of the picture. Connect the 105 directly into the amp. My audio chain is as clean as it can be. laptop to 105 to amp. I guarantee you will hear the difference when you listen to your stereo out dedicated. Hell, I think I can record it and show it to you. You probably have to listen to it via headphone because the microphone recording will be done via a canon digital camera. Probably won't be best. I will try on a samsung note 2. Probably better recording. Just do exactly how my audio chain is setup. I am 100% guaranteeeeeeee you will hear the difference. Just remove the anthem completely out of the picture.

This is how I test. Very simple too. Play the same track over and over for about 6 to 7 times until the track is imprinted into our mind and can't be forgotten. Switch over to USB DAC. The difference is not subtle. It is huge.

What software are you using on your laptop to play the audio? It's possible that when using the HDMI output it's changing the sample rate or doing some other nasty tricks to it. While I think any of us can accept that there may be subtle differences, there's absolutely no reason there should be what you're describing as huge differences unless the source is screwing up the output (as I suggest).

That is a good place to look.

With J River or Foobar there are many sound drivers available.
I prefer Kernel Streaming whe using the Oppo USB DAC.
I have not tried the HDMI but it can be difficult to get music out of a PC unscathed.

thanks dear sir.

do you have tried new DSD update?

So what I did was compare two Sources:

1) OPPO BDP-93 HDMI 1 output, to Rear HDMI Input of the OPPO BDP-105, to Stereo Analog output.

2) Mac computer USB, to Asynchronous USB DAC Input of the OPPO BDP-105, to Stereo Analog output.

My Analog output of the 105 is set to use no audio processing in the 105, and thus I can directly compare the two inputs without having to account for the fact that the DAC input bypasses such processing.

My D2v is set to take the Analog input and produce 2.1 output (my speakers are intended to be supported by a Sub). No additional processing.

I compared one of my standard, evaluation CDs.

The two Source methods, played this way, sounded identically excellent. There was no deficit using the HDMI Input.

Now obviously this is just one disc, but still, there is no patent difference in quality of the type I think you are suggesting.

Perhaps you were exaggerating the difference, but if you were REALLY hearing a difference that dramatic then, again, there is something wrong in your setup. Since you've heard it from two different computers now, the next step is to double check the audio settings in your 105. I doubt your HDMI inputs are defective (hardware problems in those would not produce the type of difference you are reporting).

You have to understand that the LPCM from the HDMI Input (when playing the CD) *ALSO* goes straight to the DAC from the point where the HDMI input is buffered and re-clocked -- unless you've got something else enabled such as Crossover processing, speaker distance adjustment, speaker volume trims, or DTS Neo:6.

I also suggest you toggle the Audio Processing > Stereo Signal setting to the alternate setting and back to make sure you are not being bitten by that bug. The bug wouldn't affect the DAC input since it bypasses what that setting does.

Bob, shouldn't the async USB DAC input sound better than the HDMI input due to re-clocking?

The USB output on the Squeezebox touch with the EDO kernel is a very nice transport. It really has a lot going for it. Nice user interface and stable data stream. Probably better than any computer USB output because it is dedicated to a single task.

I think you could use the AVR to power your multiroom.

Room correction is Audyssey.

By connecting the Apple TV to the Oppo, and the Oppo directly to your amp you would be using the Oppo DAC for the Apple TV sound.

Thanks again. I do have my marantz calibrated with Audyssey. However I usually use Pure Direct when listening to SBT and CD's

Please bear with me since i'm little new to this:
Are you suggesting that i hook the Oppo into my Adcom GFA-555ms? If so then I would have to disconnect my F L/R KEF LS50's from my Marantz into the Adcom?
IF this is correct, How would I be able to utilize the center,sub and surrounds when watching movies/TV?
Thanks again!

Not necessarily.

The firmware I'm using has that update, but if you asking with respect to the Asynchronous USB DAC Input, there is no DSD support on that Input in the 0323B Public Beta firmware. The new, DSD media files support applies to files accessed from directly attached hard drives, SMB network shares, and, possibly DLNA shares (although I'm not sure that has been confirmed yet with any specific DLNA server).

OPPO says "not with streaming" in the release notes, which I believe means no DLNA for DSD files. Yet? As you say, local storage and SMB work.
