^ Using an SPL meter is not tough. Everyone uses the modestly priced digital readout meter sold by Radio Shack.

Set the meter to Slow response and "C" weighting. Hold the meter so that it is pointing straight up towards the ceiling, at seated ear height, at your center seating position. Hold it at arm's length and keep the mic tip away from reflective or blocking surfaces. If you recline your seats for viewing, use the reclined position for seated ear height. If you have high seat backs raise the meter a few inches to clear the seat back or position it a foot or so closer to your Display to get it away from the seat back. If your seating is flush to the rear wall, also move the meter forward like this to get it away from the wall.

Play the test tone track for the Left Front speaker and adjust main Volume to get a reasonable level for measurement -- usually 75dB. Leave main Volume at at level and test the other speakers and the Sub. The goal is to trim them to get the same level for all the speakers and the Sub. Note that you use the same positioning for the meter for all speakers -- i.e., you don't go put the meter in front of each speaker or even point it at each speaker. Do everything at center seating with the meter pointing straight up.

I have the Beyerdynamic DT880 600ohm headphone. Prior to my Oppo 105 I used them with a Little Dot MK III tube amp and the stereo out's on my Oppo 83.


I sold the amp once I ordered the 105 as I wanted to streamline the system (removing the AVR too).


I can't help but feel the standalone amp resulted in a more enjoyable listening experience with music. I wish I had kept the amp, at least temporary, for A - B purposes, but alas.


I mainly use the headphones for late night movies and from that perspective I really don't notice any difference.

I reject your reality and substitute my own.

Question first: What volumes are people using with the headphone output on their 105s?


Reason for the Question:




I just got a 105 and the PM-2 Oppo headphones, figuring these are bound to be optimally compatible. Before getting them, I had
read (surprising) comments online about people keeping the volume at 90+ levels. Then I read this[ http://wiki.oppodigital.com/index.ph..._Amplifier_FAQ ]:






"[A] volume setting of 80 is actually very good. ...When the volume is set to 100, the digital audio signal is not attenuated at all. The headphone amplifier gets the maximum input level and drives the headphones at the rated output (depending on the impedance of the headphones). If volume level 100 works for your headphones, that's the best. ...A digital volume control with access to the DAC internal data path will behave just like the analog one until it reaches the noise floor of the analog components of the DAC." The noise floor is at -135dB in the ESS Sabre DAC. It is nothing if you reduce the volume 20dB or so, which is volume level 60 on the OPPO BDP-105."








Oh okay, I thought, that makes sense and I expected the PM-2s to put out normal listening volumes somewhere between 60 and 80.
Well, maybe I'm getting too old and everything, but now that I'm set up, anything over the 105's volume setting of 50 is way too loud to listen to.
Is anybody out there actually listening at levels of 60--or 80 for that matter?
Is the implication here that the 105 is actually most suited to very hard-to-drive headphones, which the PM-2s are not?
I certainly find something unsettlingly vague (not to mention auto-translated-sounding) about the "It is nothing if you reduce the [to]volume level 60" that I cited above.
Does that necessarily imply it is "something" if I have to lower it to 45?

Picked up a 105d from the dealer today to audition over the weekend. I'm finding so far that I'm getting much better results out of my trusty Bel Canto DAC1.5. In fairness it's still burning in but the gap is quite significant which my wife notices easily too. Am I better with the 103D and using the coaxial out into the Bel Canto or should I be patient?

Give us more info on how you're auditioning your 105D. What settings and connections are you using on the player? Are you enabling any speaker configuration settings? Are you using the 105's volume, or do you have volume fixed at 100? What music formats are you playing? Stereo or multichannel? In all fairness, the 105D is much more than just a DAC for less than the price of the Bel Canto.

I'm using the coaxial out from the 105D into the Bel Canto and then into my Perreaux Eloquence. Then using the analogue outs straight into the amp. This allows me to switch between the two sources at a flick of a switch.

I'm only spinning CDs. The conundrum is I already own the 103D and was hoping the 105D might show up or be on par with the Bel Canto but my ears aren't telling me that yet.

Reading through the posts things seem to improve after a substantial break in however the gap is quite wide.

Oppo BDP-105 "Sound Quality" Check Thread for Audiophiles

So, are you controlling volume with your Perreaux amp, and have the 105's volume fixed on 100? I also assume you're using the dedicated stereo output section of the 105D (either its rca or xlr outputs). At fixed volume, the 105D is outputting 2.1 Vrms out its rca's, and 4.2 Vrms out its xlr's. The 105's xlr outs are 6 dB hotter than its rca outs. How does that compare with the Bel Canto's analog outs?

That's using it as a digital transport, which bypasses the 105D's DACs. A 103 would be the same for this use.

Oh, I get it. You're doing this to test the player's DACs. I'll let the audiophiles help with this.

Oppo BDP-105 "Sound Quality" Check Thread for Audiophiles

One other thing (some food for thought). If you are using your amp's preamp section(volume control), is that there may be an impedance mismatch between the 105 and your amp's preamp section. I noticed your Perreaux amp's preamp section has an input impedance of 12K ohms (rca) and 22 K Ohm (xlr). Oppo recommends at least a 47 K Ohm input impedance for proper matching of its players. The higher the better. If you bypass your preamp section of your amp, you gain a little more impedance, as your power amp section has a 33 K Ohm input impedance. With the low impedance of your preamp, you may be losing fidelity. The music may sound strained, not reaching its full potential. I have a Levinson amp with an input impedance of 100 K Ohms, and paired with the 105, it is pure magic.

Yes that would make some sense. I'm using XLR from the Bel Canto and RCA from the Oppo and notice a DB drop when switching between the two. I will try XLR out from the Oppo.

That's interesting, I'm using a Cambridge 752 directly into Emotiva XPA-1's which have 20kohms input impedance, and it sounds fantastic.

I've a question about this. Anthem Statement P5 which is one of the best multi channel amps has an input impedance of 18 K Ohm (RCA). Are you saying that if I connect Oppo 103 / 105 directly to Anthem P5, I'll lose fidelity?

Oppo BDP-105 "Sound Quality" Check Thread for Audiophiles

^ I think the pairing will pose no issues. Another factor to look at is the input sensitivity of the amp. For the Anthem P5, it is 1 Vrms. The 103/105 put out 2.1 Vrms out their rca's. 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.

Many thanks. Based on your explanation, my understanding is that the safest way is to use a surround processor between Oppo and amp (at least in my case with a P5).

Oppo BDP-105 "Sound Quality" Check Thread for Audiophiles

^ I would try both configurations (Oppo->amp and oppo->ssp->amp) and let your ears be the final decider. However, With a SSP, you will most likely be doing digital signal processing in that component, which would defeat the digital to analog conversion of the Sabre DAC's in the 105. No reason to purchase a 105 if you do that.

I think if you reverse your set up you will be shocked-and by that I mean use RCA with your DAC and XLR from the Oppo.

This type of volume difference will totally throw you-I know from experience.

Let us know how you get on.

Haven't read through all 57 pages, but hopefully someone can give me some advice.

I recently bought a Modwright Oppo 105D. The idea is to completely integrate my dedicated stereo and multi-channel/blu-ray systems into one without losing any audio quality; but I also have a Marantz AV8801 processor... perhaps you can sense my dilemma--I'm not entirely sure what the optimal setup is. I have several options:

1. Oppo direct to amp via stereo/multi-channel analog outputs. - This may be ideal for stereo, and it would allow me to sell the Marantz, but I wonder how well multi-channel music and movies will do without the Audyssey processing on the Marantz.

2. Oppo HDMI & stereo analog outputs to Marantz - With this I could use the digital processing on the Marantz for multi-channel/blu-ray, and (I presume?) set it to "pure direct" mode when listening to stereo audio.

3. Oppo HDMI & Stereo analog outputs & multi-channel analog outputs to Marantz - This would require cable overkill, but the advantage is that I could still use the Oppo DAC for stereo & multi-channel music, and use the Audessy processing for movies only.

Any thoughts on these options?

Also, would it hurt the sound quality at all to pass the analog signal through the Marantz before going to the amp? I assume the "Pure Direct" mode would essentially just allow the analog signal to pass through without using the Marantz's DAC or converting to digital, correct?

Given you have both the modded Oppo and Marantz, you can select the option you prefer based on your own judgement in your own room, an ideal way to go. If you like the sound with Option 1, that seems the obvious solution if you don't have other analog sources. You can judge for yourself if passing the signal through the Marantz impinges on sound quality. You might use borrowed cables for your observation until you settle on a setup.

^ If you buy direct from OPPO Digital, they have an easy, 30 day return policy. All you risk is the shipping cost. If a trial like that works for you, you can save a lot of time trying to research this.

Have been a week since I got my 105D and I love it. I have it plugged into my Parasound Halo P5 via balanced interconnects. With some tunes I can hear a little bit of distortion at some frequencies, more than distortion I think is clipping. I had the volume in the Oppo at 100 but yesterday I bring it down to 75 and even at 80 there is no more distortion or clipping, so I opted to set the max volume for the stereo out at 75. Does this sounds right?</div>

Also, just in case, make sure that in the OPPO's speaker setup, you do not have any volume trims set above 0.0. There should be no positive values. If for example the surrounds are 2 dB lower than the fronts, rather than up the surrounds +2, you should bring the mains down -2.<br><br>

I have a very similar issue with my 105d, it is also only some music. I have extreme distortion on some music, yet other music is phenomenal. I also find that I can turn down the volume on the oppo to 25 or 30 (100 is full) and the distortion is almost gone but never completely and now my amp is turned up really high. Other music I can play full volume without issue. My OPPO is connected to my Yamaha preamp with balance cables. I tried using HDMI but the volume cant be turned down on the OPPO and so distorted music was so bad I could not play it. The source does not matter, I have the same issue on CD's, network shares, USB. I can play the same music on my computer or on my old bluray player and there is no distortion. I also have the issue on my headphones plugged into the OPPO which to me says there is something wrong with the OPPO. I went back and forth forever with OPPO support and they could only recommend a firmware update, they are wanting to blame my preamp and clipping, I might agree if not for the fact I have the same issue with my headphones connected directly to the OPPO. It almost seems like the OPPO has some enhancement functionality going on, that on some music, goes crazy.
I have 100GB of CD's ripped to uncompressed wav files. The music that is distorted typically is an entire CD and every song has the distortion. At the same time, the music that plays clean, sounds better on the OPPO than anywhere else I play it. I really got a lot of denial from OPPO, but then I guess I am going to eventually replace the preamp anyway. I really think there is a bug in this thing.

Have you tried cutting out the pre-amp and going directly from the Oppo analogue out to analogue in on your main amp? (or any other direct connection direct from Oppo to Main, bypassing the pre-amp?) If not, and when you do that, remove ALL connections between Oppo and pre-amp.
Also is there any chance that the worst-sounding rips are your oldest, and were done with "suss" software, and the very good-sounding rips were done with a different - and perhaps bettter - ripper? Were the poor-sounding rips done on an older computer, and the better sounding rips done with a newer computer?
Just groping here, because normally Oppo only ever improves the sound of any source, unless the source itself is flawed. Or unless you are very unlucky and have an Oppo with one or two faulty components.

Let us all know if direct from Oppo to Mains works, or if you think you may have a whole batch of flawed rips which are only now showing up their flaws with the better detail output from Oppo.

j-man54,
You wrote that you have also disortion through HDMI connection, right? then it suggest to me that you file are somehow corrupted and that the volume has nothing to do with it. Did you try the 'bad' files on another system, your computer for instance?

sorry jman54, i wanted to say: did you try to convert your file in another system, like wav or flac, in your computer. it would be helpful to know which kind of file you are using, bitdepth, samplrate, bitrate, ... all details that mediainfo will give. The only time I got distortion was with a badly ripped cd (within cdda ripper) . my 2 cents.

Very interesting discussion with the impedances!

Any idea how the oppo 105 preamp should work with an Jadis orchestra Blacksilver tube amp connected to its preamps section or otherwise going directly in an rotel rmb 1066 transistor poweramp?

"Does both setups fit"?
