Well... the posts are about the 105's processing. Certainly not unrelated.

However, maybe we should also remove posts about how to use the forums:

And posts about tongue in cheek sales of imaginary equipment:

All, of course, much more beneficial and more closely related to the Oppo-105 than anything technical the geeks on the forum might write :-)

^ Chris, we've long tried to keep discussions of audio or video theory from taking these OPPO threads down the rabbit hole, as there are whole other Forums here devoted to various types of theory discussions. There's a fine line between discussions of features/capabilities of the player itself, and general discussion of the theoretical value of such stuff. And of course it's no big deal if a post or two crosses the line. But if the discussion starts to go off on a general theory tangent, then that's when folks should rethink and perhaps take the discussion to a more appropriate thread. (Suggestion: Pick up the discussion in another thread, and post a link here for folks who'd like to follow over to the other thread.)

Random posts off topic are also typically not a problem, unless a bunch of back and forth reply posts follow. It's not the single, off topic post that's the problem (e.g., how to better use the features of the forum), it's when a tangent of off topic debate follows (e.g., why on earth did they design the forum to work that way, anyway?).

Or as I like to say, we are good at "What does this OPPO do?", "How do I make it do that?", and "Where can I find out more about that?"

We are not good at "Why on Earth did they do it that way?", or "When will they do it differently?"

It's rarely a problem. Every now and again we run into a user whose Receiver automatically disables Analog input if it detects Digital input is happening at the same time, but that's usually something you can tell the Receiver not to do.

The reason many players DON'T keep all their outputs live simultaneously is simply that they don't have the horsepower or smarts to do the right thing for each of them at the same time. The walking while chewing gum problem.

The headphone amplifier is connected directly to the ESS Sabre32 Reference DAC and offers a unique performance advantage over standalone headphone amplifiers.

There's been discussion in here of the good results people have achieved with various headphones, but it is pretty scattered. A Search in the thread might be worth a try.

In addition, there was a recent Review article which compared results achieved with various headphones compared to one, specific external DAC:

http://noblehifi.blogspot.co.uk/2013/04/oppo-bdp-105eu-review.html

That poster was using the European model of the player (BDP-105EU), but in this regard the EU and US players are the same.

The headphone output of the 105 is derived from the same Stereo audio board that drives the Dedicated Stereo Outputs of the 105.

Recent firmware changes have improved the volume of the headphone output when playing a down-mix of multi-channel content -- i.e., less "down mix attenuation".

When the headphones are plugged in, all other audio output from the player is Muted, and the Volume controls on the remote affect the Headphones only. You can also set Headphone volume in the Setup menu.

In my experience the headphone amplifier is OK. It can sound rather intimate and pleasing with high-impedance headphones, such as the HD600/650 or the HD800 (300 ohms), but it has difficulties driving really high impedance headphones (Beyer DT880 600ohm, for example). It also exhibits audible noise with really low impedance IEMs like my Westone 4. I prefer my M-cubed amp (similar to a lower-end Beta22) and my Schiit Mjolnir destroys the built-in headphone amp (of course it is a fully balanced amplifier). That said, the built in headphone amp is great for sealed monitoring headphone like the AKG K271 55ohms, Beyer DT250 250ohm and Audio-Technica ATH-M50 38ohms. The main differences I hear when using a quality headphone amp is an improved bass response (impact and texture) as well as a slightly more open sound. The effect was the most noticeable on the HD600 and LCD-2. The built in amp cannot drive the AKG K1000 and HiHiMAN HE-6 to any acceptable level, but the HE-500 works OK. In summary, the built-in amp is enjoyable, but serious headphone nerds should try a quality amp if they have mid-fi or better cans (Q702, DT880-600, HD600 and up). The improved bass performance and soundstage will be noticeable. Sorry for the long post.

No problem. I've hopefully now deleted all of my technical posts to prevent lowering the average quality and focus of the remaining posts and to prevent any confusion. If anyone comes across any I may have missed please PM me the post number so I can delete them as well in order not to offend anyone with my off-topic nonsense.

There's no need to over react or to be rude (the bolded part in the above quote). People were simply suggesting that an ongoing discussion that was straying into OT land be continued in a more appropriate place so it could be continued without disrupting the more player centric discussion here.

Sure there is. When is the operation of the 105's DAC's not on topic in a 105 forum? The 105 is a highly advanced technical piece, not your average consumer plug'n'pray $50 blu-ray player POS, and there are clearly some that want to discuss it on other levels, to know why it might be better than another device. If technical details of the 105 are not wanted here then clearly they are of low value. At this point I'm almost surprised my posts weren't summarily deleted without my knowledge. There's all kinds of garbage in this forum (I know, I've read every single post), and yes, many rabbit holes way off topic, but somehow someone calls out posts that are both generally and specifically relevant to the operation to the 105 as too much information, and apparently the forum (or at least the master of ceremonies) seems to agree. Therefore, I repeat: my posts have clearly made the forum less valuable to its mainstream readers and many have now been deleted at least to the degree that is under my control. I'll let you guys get back to the proper capitalization of the "son of god" (as apparently religion is more on point than the 105's DAC's).

Chris, as best I can see nobody asked you to delete your posts. What was requested by Jim was that the discussion of upsampling theory be CONTINUED in, for example, the Audio Theory forum here. Heck, glancing back at the last few pages, I'm not even sure your posts were the ones that caused him to ask that.

It's a common enough situation here; discussion of player details evolves into discussion of theory and someone pipes up with the reminder that general theory stuff would probably be better posted in a theory forum. That's not saying the discussion started off out of line at all. Just a suggestion that it's starting to go off on a tangent.

post #5441 of 10185
I suspect a lot of people nowadays are using the 105 as a pre-processor.

I've just emailed Oppo requesting that in the next firmware update they have the Oppo "remember" the last selected input after it is turned off, like a typical AV receiver does.
In my case when the player is turned back on I want it to automatically selected HDMI-back (my PVR). I watch my PVR far more than I do blurays (the current default on power up).

Does anyone else think this is a good idea?

I think it's a great idea. But, we were told that the OPPO is a Blu-ray player first and it will default to that setting upon power-up.

Yep, they said the same thing to me, but then followed with "we are looking into a possible inclusion through a future firmware release."
Lets hope so!

Perhaps an option for the user to set the default input on power up is all that is required ?

Your posts contributes relevant technical value, no need to over react. A forum is about discussions with discussion information is shared. I hope you reconsider your stance. Opinions are individualised, not a voice for all.

Received this email from Oppo

When sending a signal through the HDMI port into the player, there is still a change the audio will go out of sync when there is a change in the audio from the cable box from 5.1 to stereo. The solution to this error is to simply go to a SD channel then back to a HD channel. This will resolve the audio and video synchronization errors until we can resolve them through a future firmware release

Really? Okay, thanks for providing that information. I was fully aware what was causing the lip sync/vid anomaly (a transition of 5.1 audio programming to 2 channel programming), but was unaware of a method to resolve it. I haven't even tried hooking my fios dvr into the Oppo in over a month. IMHO, it's futile to implement the suggested interim fix because many local commercials are 2 channel audio broadcasts, so the lip sync/vid issues will be incessant while watching normal tv programming, aside from dedicated non-commercial programming channels (i.e. pay cable movie channels).

post #5448 of 10185
^ The difference is that in the prior firmware it was happening at every transition, as you describe. Now it is relatively rare (enough so that it originally looked like OPPO had completely fixed the issue with this firmware), so the workaround may not be as bad as you think.

Exactly. I suggested moving it because as a past participant in a couple of these death spirals, it was obvious that oversampling-adds-useful-info vs. oversampling-just-removes-the-need-for-brick-wall-filters was going to lead nowhere good.
post #5450 of 10185
^ Thanks, Bob, for that info. I'll have to give it another try.
post #5451 of 10185
I've got a 4.1 setup - L and R fronts, L and R surround (actually mounted behind me but I've always used them as "side" surrounds) and sub:

Would there be any audible advantage/disadvantage to setting the downmix to 5.1 or leaving it at 7.1?

The graphical "channel diagrams" seem to indicate I should set the downmix to 5.1, but I suspect it's all moot. biggrin.gif

post #5452 of 10185
^ It may help to realize the ACTUAL down-mix is the lesser of what you select for the down-mix setting and the speakers you have enabled.

So with LF/RF/LS/RS/Sub enabled, a setting of down-mix = 5.1 or 7.1 will produce the same result -- i.e., a 4.1 result. The exception to this rule is that with Stereo or LT/RT down-mix (i.e., 2.0), you can RE-enable the Sub (selecting that down-mix will default the Sub to OFF) to get a 2.1 result.

Note that if you have only 2 Surround speakers, they should be wired to the SIDE Surround outputs, regardless of how far back you have them physically placed.

Bob, your reply makes me wonder if I should reset my rear surrounds to off. I rarely turn on the amps that drive the rear surrounds, because there is rarely any 7.1 program material. I did turn the amps on for Life of Pi, and found the 7.1 quite effective for that movie. I suppose I could reset to rear surrounds to on for those rare occasions if the down mix is impaired by leaving those speakers on. I'm using the LT/RT down mix scheme with the stereo output for front LR of 7.1. The mains are set to large, because I use balanced output for stereo.

That's the point where I'm at. I hook my STB to my TV and get audio to my system through ARC. The video resolution takes a hit (my box outputs up to 1080i), but I don't have to deal with A/V Sync issues.
post #5455 of 10185
Hello, I received my Oppo BDP-105 recently and gave a few tries using my old headphone amp HeadRoom Ultra Micro Amp and Sennheiser HD800 headphones. Unfortunately I found out that build-in headphone amp suffers in mid-range frequency, so I had to use a separate amp. Now I'd like to use the player in its full capacity (i.e. with video). I have Yamaha RX-V 1900 receiver with I plan to use with the Oppo player for both headphone and speaker listening (setting HDMI directly to TV set). Do you think this Yamaha receiver will match (at least somehow) this palyer, or I should immediately buy another amp? Thanks, I'd appreciate any advice.

Most folks with a 7.1 speaker configuration leave all 7.1 speakers enabled and set 7.1 down-mix regardless of the content they are playing. If you play 5.1 content or 2.0 content (with DTS Neo:6 Mode OFF), then of course the unused channels are silent, but that's no problem.

I don't understand your last two sentences. Why are you setting Down-mix to LT/RT? Are you sure you don't have the Down-mix setting and the Stereo Signal setting confused?

The down mix is set to LT/RT so I can substitute the unbalanced stereo output for the front LR 7.1 output of the 105. I set the mains to large, because with the LT/RT the crossover setting to the subs is applied to stereo even though there is no output to the subs. If the mains were set to small, LF would be cut off to the mains without any compensatory LF to the subs. I think I followed some combination of advice from you and Oppo in setting this up. It seems to work. The front two channels of surround sound benefit from the special analog processing Oppo devotes to stereo, and the KEF Reference 107/2s with their 107/2 KUBE reach down to 20 Hz quite effectively for those low pipe organ pedal notes. Separate .1 goes to the subs.

There are TWO DIFFERENT settings. It may be you've simply confused them in your mind while posting here, and actually have things set up correctly.

The first setting is Setup > Audio Processing > Stereo Signal. Setting Stereo Signal = FRONT LEFT/RIGHT configures the Dedicated Stereo Analog outputs (both the RCA pair and the XLR pair) to respond to all the settings that normally affect the LF and RF outputs of the multi-channel Analog set -- so you can use, for example, the Balanced (XLR) Stereo pair in lieu of the normal LF/RF RCA jacks when wiring the multi-channel set.

The second setting is Setup > Audio Processing > Speaker Configuration > Down-mix. *THAT's* the setting that offers "LT/RT" as one of its choices. You should have that set to Down-mix = 7.1 and not to Down-mix = LT/RT. Down-mix = LT/RT is a variant form of reducing the output to Stereo only, which you certainly don't want to do in your 7.1 speaker configuration.

I also hook up my STB directly to my display (Panny VT30), but I output native resolution from the STB (720p or 1080i, depending on the channel) so that my display does the upscaling rather than the STB. IMO, PQ is fantastic (I'm sure the display does better processing than the STB - you should give it a try).

Just got my 105 today.

I have searched but I can't find a simple answer to my question. Maybe there isn't one smile.gif

Can iTunes be streamed wirelessly from my IMAC directly to the OPPO?

Thanks.
