Have had the 105d for 6 months or more- replacing denon 3800bdci for video. still not entirely sure about effects of darbee with my flat panels. Sometimes it seems to be useful.


Regarding Audio, Using the 105d direct via nordost Valhalla xlr into dartzeel 2-ch amp into Aerial Acoustics 20Ts via nordost Valhalla and using Aerial's sw12 subs- comparing it with mark levinson 390s cd processor (same set up)- mark levinson player sounds better but not by a huge margin- almost sounds good enough to get rid of the levinson player.


Regarding hometheater, the 105d has replaced a enlightened audio designs theatermaster signature 8 (5 channel processor) and it is amazing how good it sounds running the audio from a TiVo roamio through it. It really is unbelievable how this one box can do so much and do it well enough to satisfy both audiophiles and videophiles.

Thinking about getting the 105. Is it alright to feed the analog outputs of the 105 into my Denon X4000 AVR CD inputs or will the Denon mess with the sound quality? Want to use my sub woofer that's controlled by the Denon.

Anthem P5 Amplifier

Those players will put out 1 Vrms at around a 6 dB reduction of their max volume (100). This equates to about 12 volume steps/clicks of the 103/105's volume control. So, the voltage divider (voltage attenuation) created from the output impedance of the 103/105 (100 Ohms) and input impedance of the Anthem P5 (18 K Ohms) is fairly small, which means you should be able to reach the Anthem amp's max output (if you so desire) near a 103/105 volume just shy of 90, with room to spare.

Reports from owners who have connected their Oppo players direct to amps have been mixed. A few say they have maxed out the Oppo volume control and wish they could increase vol a little more for quieter passages of classical music or a low output audio disc, while most say they have more than enough reserve volume, and typically listen with volume in the 40-80 range.

I've read that Oppo recommends a 47K input impedance for a load, so just about anything at or over 47K will pose no issues. That's not to say a load of a little under 47K won't work...it's just not ideal.

There's other factors that I will not discuss that can affect fidelity between player/amp (i.e. load on the output amp stage of the 105). If you want more details, read Official OPPO BDP-105 Owner's Thread post 8287 in the 105 owner's thread by Laird Wiiliams.

I was catching up on my reading on AVS and came across your post on the Anthem P5. I'm afraid you explanation concerning the gain structure of the P5 isn't quite correct. The P5 outputs 28.3 volts with an input of 1 volt. This equates to a 100 watt output into an 8 ohm load and 200 watt output into 4 ohms. A 100 watt output with a 1 volt input is also given the specifications section in the P5 manual. Just shy of 90 on the OPPO volume control will give a reduction of about 5 dB in voltage output, let's say 6 dB to avoid much math. That amounts to 1/2 the voltage output or about .5 volt. That drive into an Anthem P5 will result in an output of about 25 watts into 8 ohms.

The required input potential to obtain the full output from the Anthem P5 into an 8 ohm load is about 1.8 volts. Stretching my math skills puts this output level down about 1.3 dB from the 2.1 volt full scale output of the RCA's in the OPPO unit. This level is around 3 units, or a setting of 97 on the volume control.


I own a BDP-105, but I don't directly drive power amplifiers with the unit. I didn't realize that the 105 wanted to see a 47k Ohm or higher input impedance. That input impedance is quite high, higher than many solid state amplifiers including the Anthem P5 as you note. It seems odd that OPPO gives that high figure because the op amps it appears that OPPO uses (TI LME4562) in the 105 could drive loads down to 600 ohms with little degradation. Driving 600 ohm loads is the first claim on the datasheet for the LME4562.

I guess I'm a little confused with your math in your text I highlighted above. Half the max voltage output of a 103's/105's rca outputs is .5 * 2.1 V = 1.05 Volts, which is a 6dB reduction (12 volume clicks, just shy of 90).

I agree with your math. The point I was trying to make was that a 1 volt input (due to a setting of 90 on the OPPO volume control) to the Anthem P5 would result in a 100 watt output into 8 ohms, not full output (max output) as was, at least to me, implied by your text. To get full output would require something like 1.8 volts which is around 97 on the OPPO volume control.

Such a match between the OPPO and P5 seems like a good result. It optimizes the S/N ratio of the OPPO and yet doesn't overdrive the P5. Many people aren't comfortable with high volume settings on a preamp (the OPPO in this case) but actually such settings often optimize the S/N of the system.

Ahhh, yes. I see now. The P5's max power output is 325 watt rms into 8 Ohms per ch. So, square root (325*8) = 50.99 V. With the P5 having a voltage gain of 28.3 V(29dB), that would compute to an input sensitivity of 50.99/28.3 = 1.8 Volts to reach max P5 power output into 8 Ohm. Yeah, high 90's 105 vol driving the P5 would produce ear piercing audio!

Pure stereo settings

Hi everyone... I've had by 105 for a year now... is there a way to bypass all the speaker config settings so I get as pure a stereo signal as possible? (e.g. bypass speaker size, crossover, distance, dB, etc).

Thanks.

Ooops.... I had also posted this in the main 105 owners thread... and it has been answered there.

Bigguyca I'm awaiting delivery of a Parasound A23 which I intend to run directly balanced from my BP 105 into B&W 685's. i'd love an evaluation of this "system" and your opinion / necessity of the addition of an Emotive XSP-1. I've just started trying to evaluate the impedance match of these components. Right now the math is beyond my ability to analyze.

A digital file is a digital file. What is the Oppo BDP-103D doing differently to the digital file that the Oppo BD-P 5100 is not if the pre amp is processing the file? What is the Oppo BDP-103D doing that creates better sound quality over HDMI?

^Nothing. The difference between the 103(D) and 105(D) is that the 105 unit has a high end DAC.
The way they both process files is exactly the same.

You're talking about the "Sony" Blu ray player, right? (bdp-s5100). That's not an Oppo player...

This thread is dedicated to the sound quality of the Oppo 105, which has 2 audiophile quality ESS Sabre 32-bit DACS. The sound quality of that unit would be measured via the 105's analog outputs (rca and xlr). If you choose to simply bitstream audio out of your Oppo player (i.e. use it only as a digital transport) to your pre/pro, then the Oppo players are really doing nothing more than serving the digital file/stream to your pre/pro for processing. So, strictly speaking from an "audio/sound" viewpoint, as you're asking, there theoretically should be no difference, until that digital audio is converted to analog by the downstream device. You will get faster loading times of shiny disks and probably more stability with an Oppo player over a cheaper player, however.

^ Lol, sorry I was assuming the comment saying "Oppo BD-P 5100" was a typo and that you meant to say "Oppo BDP-105".
I have no experience at all with the SONY (BDP-S5100) player.

can you simultaneously use xlr analog outs for right and left speakers and rca outs for subs? my levinson cdp lets me do this which is fantastic

Both outputs are always active, but without a proper crossover on both the speakers and the subs, you're probably going to end up with a lot of extra bass.

Edit: Which RCA outputs are you thinking of using for the subs? Since you mentioned subs in the plural, I was assuming you were talking about using the dedicated left/right analog outputs for subs rather than using the subwoofer output that's one of the 7.1 analog outputs. If you're thinking of using the 7.1 channel subwoofer output, then Bob's advice is spot on, as usual.

Yes. Set Stereo Signal to FRONT LEFT/RIGHT and the Dedicated Stereo Analog outputs (both the RCA and the XLR pairs) will respond to all the speaker configuration settings that normally affect the Left Front / Right Front speakers of the multi-channel Analog set.

Then set your Speaker Configuration as if you were wiring a 2.1 system entirely from the RCA jacks of the multi-channel set. For example, if you want bass steering to happen when playing stereo content, set LF/RF to SMALL, Sub to ON, and pick a Crossover frequency.

The XLR outputs are, by design, +6dB hotter than the RCA outputs. (Your amp may already compensate for this -- perhaps by a switch setting.) So be sure to check the volume balance with a calibration test track and an SPL meter. I.e., you'll need +6dB more Sub boost to get the RCA Sub output matched to the XLR outputs. (Do this with the volume knob on the Sub itself.)

I was planning on using the rca analog outputs sending the same signal as the xlr to subs with built in crossovers- so both xlr and rca analog outs are always active?

Yes. Think carefully about what content is present on each. That depends on the Stereo Signal setting and the Speaker Configuration settings. This is particularly important if you are listening to multi-channel content. For example a down-mix on the independent stereo outs will have down-mix attenuation but no LFE. Meanwhile the multi-channel outs may have no, or a different, down-mix.
