Today I noticed that connecting a monitor to the 105 HDMI 2 Output negatively affects the fidelity of my 5.1 Analog signal.

My 105 is in the 5.1 Down Mix mode. All 5 speakers are set to Large and the subwoofer is set to Off in the Speaker Configuration screen. I have the Stereo Signal setting configured to utilize the dedicated stereo outputs for the Front Left and Front Right signals. I use the Analog outputs to feed 3 identical stereo tube amplifiers. The HDMI 1 output is connected to my main TV. The HDMI 2 output is connected to a small monitor so that I can view the 105 Setup Menu.

Today I was poking around my system and at some point I removed the monitor from the HDMI 2 connection. Then playing a 5.1 music disc; I felt that it sounded clearer. So I sampled several discs, connecting and disconnecting my monitor to and from the HDMI 2 output. When the monitor was disconnected the music sounded clearer and because of this the surround field improved as well. I am convinced that there is a degradation of the audio signal when the HDMI 2 output is utilized. I couldn't recognize any degradation when performing the same sampling with the monitor connected to the HDMI 1 output.

At a guess, your tiny monitor is accepting a limited form of HDMI audio, and that's screwing up what can get sent to the Analog output path. This would be more likely if you have Dual Display set instead of Split A/V. I'd need to go into more details of exactly what hardware you are using and how you have things configured to really figure this out, but if turning HDMI Audio OFF fixes the problem then there's no need to dig into the particulars.

---------------------------

ETA: It's also possible you were actually HEARING audio coming out of that small monitor -- without realizing that was happening. And that unexpected, down-mixed, and likely low quality audio was screwing up your perception of audio coming from the regular speakers.

I do have Dual Display selected. The monitor is an older HP LCD monitor with DVI inputs and I use a HDMI-to-DVI adapter. But like you said, no point in analyzing this any further. Thanks for your help Bob!

SOUND CHECK!<br>
With 94+ pages of hardware, firmware, and software tech-talk growing on the other BDP-105 owners thread, this thread is intended for "sound" only feedback, audio related discussion for the audiophile people and their new 105 players. Your sound related comments would be greatly appreciated about your experience and comparisons so far with your new BDP-105 player. Thanks in advance for your replies. Happy listening. <img alt="smile.gif" class="bbcode_smiley" src="http://files.avsforum.com/images/smilies/smile.gif"><br><br><br><ul class="bbcode_list"><li>How does your new Oppo BDP-105 player <b>SOUND</b> to you?

<li>Comparisons to <b>other players</b> or other <b>DACs</b> you've tried before? Same/Better/Worse?</li>
<li>Sound quality when using the <b>RCA</b> analog stereo output?</li>

<li>Sound quality when using <b>5.1 or 7.1 analog</b> output <span style="text-decoration:underline;">instead of HDMI</span>?</li>

<li>When connecting an <b>HDMI input</b> source, Cable box, etc?</li>
<li>When <b>streaming</b> through Airplay or other methods?</li>
</ul>
Just compared:

a) Standard stereo CD played by 105D (Natalie Merchant - self-titled) analogue out via balanced XLR to pair of Geithain RL906 active speakers,
b) Same CD played by 105D digital out via coaxial to Dangerous Music Convert-2 dac then out via same balanced XLR cables to same speakers, same position in same room.

Using a) the recordings lacked resolution with voices and instruments melding in to each other.
Using b) the recordings were quite the opposite with each instrument and voice having its own very individual sound character (apart from the massed strings). Much easier and more enjoyable to listen to and less soporific.

The difference in sound quality was massive - like listening to two entirely different CDs.

From this, and the fact that a sound file of the same CD played via the 105's dac is much more resolving than a), I've concluded that for primarily 2 channel CD-spinning music listening the 105D is a dud.

Next step is to compare:
b),
c) a lossless file of same CD played using the 105's dac, and
d) the same file using the DM dac.

It seems as though you reached a universal conclusion from a very particular set of premises. I think few would agree with your conclusion. The Oppo 105D may not be the finest sounding analog stereo player, but it's certainly no dud.

I agree the Oppo is in no way a dud. I've never heard it described that way. I'm wondering how many hours he has on it. My Oppo sounded harsh with a two dimensional sound stage at first. But after about 200 hours the harshness went away and it opened up beautifully with pretty awesome instrument separation.

Preliminary results following from my previous post - stereo SQ in ascending order of goodness:

1. Oppo 105 CDP > balanced XLR > Geithain RL906 speakers

2. Lossless file from ipad2 > Oppo DAC asynchronous USB > balanced XLR > Geithains

3. Oppo 105 CDP > coaxial >Dangerous Music Convert-2 > balanced XLR > Geithains

4. Lossless file from ipad2 > DM Convert-2 asynchronous USB > balanced XLR > Geithains

Dramatic respective improvements in SQ from 1 to 2, and 2 to 3.

3. and 4. equally enjoyable:

Using the ipad into the DM converter is somewhat unnerving as the musicians seem to be more in the room with me - hopefully something I'll get used to in time.

By contrast playing the CD with the Oppo into the DM converter is a more relaxing listen as the music has a softer, less sharply rendered quality.

(BTW the calibration setting on the DM converter was set to -18dBFS for all tests.)

Next test: Oppo 83 via coaxial into Oppo 105 DAC vs 1.,2.,3., and 4. - awaiting RCA to RCA coaxial cable.

Hi pibroch,

I am following the thread and enjoy it. I may do some serious listening comparison when I get enough time (and upgraditis again...)
Nevetheless, you mention that you connect your Ipad 2 to the Oppo via USB. How is that feasible? Direct connection? adapter? I dropped any IPhone a while back, but may return following company decision to allow only iPhone devices for mail... thank you in advance.

Hi Arrius,

..... you're welcome

Two connected cables:

1. The small end of an Apple "Lightning to USB Camera Adapter" patch cable to plug into the Ipad2.

2. Type A to Type B USB cable which came with my new Oppo 105D.

The USB socket end of the camera adapter accepts the USB Type A plug of the main cable whose Type B plug goes into the back of the Oppo.

Thank you pibroch! Good to know that way of connecting Ipad to Oppo. I'll keep this in mind in case I go the all Apple route.

I'm having a hard time finding the answer to this question and was hoping someone could help. Can the OPPO 105 output stereo via the XLR balanced outputs and also a movie soundtrack via the HDMI cable? I'm not trying to listen to stereo at the same time I'm watching a movie, I just want to feed the HDMI to a soundbar for movie watching, but when I playback a CD or music, I want to feed a dedicated 2 channel amp.

The reason I'm confused is the OPPO 105D manual states "If your audio system offers only stereo audio inputs, or if you would like to connect a dedicated stereo audio system in addition to the surround audio system which is already connected to the HDMI or S/PDIF outputs, you can connect the dedicated stereo audio system to the FL (Front Left) and FR (Front Right) terminals of the player."

Why is there NO perfect equipment, only compromises?

Yes, all ouputs are live simultaneously. The exception is when using the headphone jack: other audio is muted then.

That's about configuring the player to provide yet another set of stereo outputs; it doesn't turn off anything.

Question - I've not been around for a while, and I've been dealing with this issue for a while - thought I might ping the crowd and see if anyone else has seen this.

I have the Oppo BDP-105 - working beautifully for everything, latest Firmware etc.

When I run the HDMI into my Denon X4000 receiver (Latest Firmware), I get distortion on the Main L and R channels whenever the soundtrack swells during a movie. The Center, and all Rears are perfectly clear, it's only Main R and Main L - and I believe it's only when using the OPPO. I don't notice it when I watch any other HDMI input, and it doesn't seem to matter what surround sound mode I use on the receiver.

As I said, I've had this issue for a while now, and the warranty on both are up - so I'm hoping it's a setting issue and not something I need to pay for repair on. Any thoughts or suggestions?

The HDMI levels can't clip because there's a fixed definition of full scale for the digital audio signal, so this is likely a problem in the settings in the Denon. Try lowering all of your speaker volume trims in the Denon by the same amount.

Yeah, I knew that, I was just wondering if this might have been a common issue. I'm honestly afraid that the receiver might be distorting the information as it's being sent to the channels. I've already checked the levels and none of them are bumped up at all. I even shut off the Audyssey and reset and re-ran the Audyssey to see if that fixes it.

I'll spend more time with it - maybe it's not just the Oppo as it seems.

I have been wanting to upgrade my cheapie old denon CD player for years. I recently learned about SACDs (yes, I am very out of the loop). Since I already have a Marantz power amp and pre / pro I thought I would continue along those lines and get a Marantz SACD player. During all of this time, I kept seeing a great deal of fantastic reviews for Oppo gear. I changed my mind about the Marantz SACD player and ordered the 105 Darby.

I am excited to listen to my old CDs with hopefully much more clarity and musicality. I also have been buying a few SACDs and DVD-A discs of my old favorites so I will have some cool stuff to listen to when the Oppo gets here (should be two days).

I am sure I will have some questions when I start setup. My first is that this will be primarily for 2 Ch. audio at first (I will address video later). Should both the HDMI as well as the RCA interconnects be hooked up at the same time? I want to try to do a little testing to see which might be better between the digital output and analog output. If both types of cables are hooked up, can the output type be selected between the 2 HDMI and RCA output?

The HDMI outputs are identical for audio, so you would need HDMI2 only if you want to try video output that is Mediatek only, without Darbee or VRS. Both of those can be turned off, but the circuitry is different, so you never know...

All outputs from the player are live at the same time, so switching would be done at the receiver.

I'm sure you're aware that digital audio output means you're using the audio DACs of your pre/pro, and that you need to use the analog/RCA outs to use the DACs of the 105D. If you prefer digital, you wasted your money and should have bought the 103D (video is the same with both players; the main difference is the audio DACs).

How is it possible that bass management is not possible in JRiver? There is an entire suite of tools in JRMC. In fact there are many recommendations that BM be accomplished in JRiver prior to Dirac which is prior to Oppo. All done in the digital domain which is ideal.
I think.
I use the Oppo solely as a DAC (and a disk spinner). HDMI or USB in . Then the analog is passed to the Emotiva XMC for volume control and on to Wyred4Sound MC amp.
I'm not sure what the exact meaning of "renderer" is. I think of that as the Oppo pulling content directly from a hard drive somewhere. Again I admit I might have it wrong. That's not my method.
I have an i5 Broadwell NUC solely used as a JRiver platform which reads content from a Synology NAS.
My main objective is to determine if there is a performance difference between HDMI 2CH in vs. USB DAC in on the Oppo 105D.
Thanks Bob, and everybody.
It is possible to do bass management/DSP in JRiver and into an Oppo and out to analog or HDMI. BUT ONLY IF it is an X.1 signal via HDMI.
As I understand JRiver does not support HD lossless audio encoding, so this would likely only work in X.1 PCM.
I'm not sure it JRiver has HD lossless decoding or if it is ONLY pass-through. If it does, then you will be happy.

Technically you could do EQ and filtering/DSP in 2Ch mode via USB or HDMI to analog as well. Such as a HPF or low-shelf boost. Which may or may-not cause a problem for your mains (extra bass or absence of bass etc...)

Just be careful not to clip the DAC, otherwise SQ will be compromised. If in doubt, apply only EQ cutting, no boosting.

I know it works in PCM because I've tried it (I haven't tried DD/DTS HD though...)

As for pre-proessing DLNA stuff, I highly doubt JRiver has that ability. But that is a limitation of JRiver not Oppo.
So if you are using DLNA, then you are likely out of luck most probably.
