Oppo BDP-105 "Sound Quality" Check Thread for Audiophiles - Page 42

post #1231 of 1448
I just got my 105 and have sone setup questions for the experts. My pre/pro is a Marantz AV8801. I will use XLR for 2 channel music (no subs for this mode, pure direct.) HDMI for movies and 7.1 in for sacd. Will be running my Sonos play and htpc through the dac's (when I can get the damn driver to work!) Should I use the down mix? Any other tips or tricks? Thanks in advance. I run an 11 channel system with 4 subs if that matters.

I, too, am having a problem with my 105/Marantz 8801 combo--sorry, but I can't help with yours! Anyway, I'm using the multi-channel analog outs (the main LT/RT, not the dedicated m-ch LT/RT) with the Sound Processing Stereo Signal set to Front Left/Right on the Oppo. It sounds great in multi-channel, but when I select the Stereo layer on SACDs (a few have too much direct sound in the rear channels for my taste), the sound is terrible! It collapses into the middle, sounds hollow...just nasty! When I select the Stereo layer and use the HDMI output, it sound fine (with the obvious loss of rear channel info and slightly less width but essentially the same tonal balance.) Is there some setting that I'm missing on either the Oppo or Marantz? I should add that standard RBCDs sound fine either way, with just a bit more warmth via analog.

When using stereo analog out from the oppo to the marantz, select "pure direct" and/or "source direct " from the marantz.

i suspect the 8801 is performing an a/d/a conversion with your actual setup.

That didn't help, besides, the analog inputs bypass all ADA conversion.

I am using the dedicated rca stereo out for the left ,right , 7.1 input to my Marantz AV 7005 . Can I still use the dedicated XLR stereo out to the CD input of the Marantz as well.

When playing cds I will get "double bass" if I have speakers set to small, a 60hz crossover, and the downmixed stereo setting ? Meaning that my mains will get a full single so the material below 60hz will go to both the sub and mains. If that is true, would I also get double bass on 5.1 material?

I suspect you are not going to get a handle on this until you actually try playing with the settings using a Calibration disc -- such as the LPCM tracks from AIX Audio Calibration, Blu-ray.

First off, you still seem to be confusing what happens on the Dedicated Stereo Analog outputs with what happens on the multi-channel Analog outputs.

A suggestion: Start by ONLY wiring the multi-channel Analog outputs. You can play stereo content through them as well as 5.1 or 7.1 content. When you play stereo content the Center and Surround speaker outputs from the player will just carry silence. Then you can use your SMALL speaker settings and Crossover setting to get bass steered to the Subwoofer for either stereo content or multi-channel content. Once you have a handle on how that works, THEN you can start experimenting with use of the Dedicated Stereo Analog outputs -- either wired separately or wired in place of the Left Front / Right Front outputs of the multi-channel set.

I posted recently about adding a Oppo 105 to my 2 channel system. So, I finally got around to doing a comparison of the Krell SACD Standard, Oppo 105 bought in February 2013, Oppo 105 bought in December 2013 and Logitech Transporter. All were connected with balanced cables to a Kramer VS-4X switch and balanced cables to Krell 400xi amp with Dynaudio Focus 360 speakers attached t that.

The Oppo 105 bought in February is attached to my home theater and has gotten daily use since then as it passes the Directv signal to the TV.

I bought the 2nd Oppo for my 2 channel system as the Krell will no longer play the SACD portion of hybrid SACD's. It defaults to redbook CD. It is also nice that the Oppo also allows me to play blue ray audio and DVD audio discs.

I compared Willie Nelson's Stardust SACD only disc with the Krell, old Oppo and new Oppo.

I compared Steely Dan's Gaucho hybrid SACD with the old and new Oppo.

I compared Beck's Sea Change blue ray audio disc on the old and new Oppo.

I compared Beck's Sea Change redbook CD on the Krell, and old/new Oppo.

I compared Beck's Sea Change blue ray on the Oppo to Beck's Sea Change redbook CD on the Krell

I compared Beach Boys Pet Sounds DVD-A on the old/new Oppo.

and finally compared Beck's Sea Change ripped in FLAC 16/44 and streamed from a Buffalo NAS device to the Transporter and old/new Oppo.

To start, I am not much of a believer in break-in of equipment except for speakers.

What I found was that I really like the Krell sound much more than the Oppo when I was able to compare it with redbook CD's and SACD only discs. The high's were higher, the bass was more pronounced. It sounded like I was in the 2nd or 3rd row by comparison to the Oppo's which put me in the 4th or 5th row.

When doing the same comparison with the old and new Oppo, I was surprised to find a difference. The old Oppo was much more pronounced than the new Oppo. There was just more pop to the drums and cymbals. The mid range in particular sounded much more alive and the bass was much fuller. This was true across every medium except FLAC files.

The Oppo of course did sound better when comparing a lower audio format on the Krell. Like the Sea Change blue ray played on the Oppo sounded FAR BETTER than the redbook CD played on the Krell.

When it came to FLAC files, I couldn't tell the difference across any of the machines, Transporter or Oppo's. Maybe my ears were a little fatigued at this point. However, I listened many times over and couldn't discern any differences. I don't have any 24/96 files to compare.

Anyway, thought I would pass along what I found...

^ Interesting findings there btscott.
The more I keep playing with analog audio the past couple of years, the more I think there may actually be something to the "burn in" theories.
I think sometimes though, we get caught up in too many details, and then things start tripping over themselves in the search for the best sound.
More than likely all of your units offer fantastic sound reproduction and would make any listener happy.
I do love my BDP-105 and it by far produces the best sound I have ever heard.
I really can't imagine it sounding much better (to me). I think I would have to get even better speakers and amps to hear any more difference, lol.

Oppo fixed my BDP 95 for free and it was out of warranty. Can't beat that.

Thanks Bob for taking the time to explain that. I believe I understand what you are saying. I am not at home now, so I can not pop in AIX disk. Here is why I was asking the question.

When gsr says "if you have the dedicated 2 channel outputs set to "Down-mixed Stereo" (the default), then the crossover settings do not apply to those outputs and your headphone amp will get a full range signal." - I interpret this as my mains will get the entire signal, thus including bass below my 60hz crossover with down mixed stereo setting.

When you say "I believe your misunderstanding is in thinking that if you set Stereo Signal DOWN-MIXED STEREO then the Subwoofer output will be silenced. Not true. The Subwoofer output is part of the multi-channel configuration -- not the dedicated stereo configuration. And both multi-channel and dedicated stereo are live at the same time -- even though you only may be intending to listen to one of them. So the Subwoofer and the REST of the multi-channel jacks are still live when you are listening to that stereo content from the CD. It's just that there's no audio on the CD that goes to Center or the Surrounds so you don't hear them. But there IS bass in the stereo on the CD, and if you have the Crossover engaged for the multi-channel outputs, then the Sub gets a portion of that bass due to the function of the Crossover." - I interpret this as when playing a cd with 2.0 sound any bass below 60hz will get steered to the sub...with down mixed stereo setting and speaker set to small.

So I conclude my mains are getting bass below 60hz and my sub is getting bass below 60hz, in Down mix stereo setting unless I set the speaker to large.

If you leave the dedicated 2 channel outputs set to down-mixed stereo, they will get a full range signal regardless of how you have your speakers configured (large / small). If you set the dedicated 2 channel outputs to front left/right, they will get a full range signal if you have them set to large or will have bass redirected below the crossover point if you have them set to small. So when you say:

The Oppo is doing EXACTLY what you're telling it to do:

1) When you set the dedicated stereo outputs to down mix stereo the speakers connected to those outputs will receive a full range signal. But the small / large settings still apply to the other multi-channel outputs, so if you have front left/right set to small, you should expect deep bass content to come from your subwoofer.

2) When you set the dedicated stereo outputs to the front left/right setting, then the small / large settings apply to those outputs, so the speakers connected to those outputs will not receive a full range signal if you have them set to small.

If you set the dedicated stereo outputs to down mix stereo they will ALWAYS get a full range signal regardless of whether you set your speakers to large or small. The large / small settings only apply to the dedicated stereo outputs if you configure them with the front left/right option. If you're using the dedicated stereo outputs as part of a multichannel system (5.1, 7.1, etc.), then you should configure them as front left / right.

Hi all,

I am considering investing in the latest Oppo unit for my 2 channel music system for playback of SACD discs, DSD files and blu ray audio discs, but can't decide between the 103 or 105. My options are essentially:

a) Get the 103 and separate DAC (likely the NAD M51 due to its HDMI input) and run a HDMI cable from the 103 to the DAC (I appreciate that the SACD DSD stream will be converted to PCM and down sampled to 88.2Khz). The DAC will then run into my pre-amp.

b) Get the 105 and use its internal DAC and analogue stage to run a balanced connection straight into the pre-amp.

The trade off as I see it is to sacrifice the benefits of direct DSD to analog conversion in the Oppo for possible improved (possibly, subjectively . .) digital analog conversion in a dedicated off-board DAC, or vica-versa. The overriding objective is the best possible 2 channel audio reproduction.

So, a couple of initial questions:

1. Which option is likely to produce the best sound quality for SACD's and DSD files (other music files are handled by a separate streamer, so only these two formats [along with bluray of course] are of concern).
2. How well does the Oppo Media Control app work for controlling the playback of music (particularly DSD) files stored either locally (USB stick for example) and via a NAS on the network?
3. How are DSD files played and output by the Oppo's - are they available on all digital outputs, or only analog and HDMI? On HDMI do they get down converted in a similar way to the SACD DSD stream?

Anything else worth knowing about playing DSD files . . .

Thanks in advance . . .

There's also a 3rd option: get a 103D instead of the 103 as it CAN transmit DSD over HDMI1. Not sure if the NAD M51 can accept a DSD signal, but if it can this might be a pretty good compromise between the 103 and 105. Or use the HDMI2 output on the 103/105 which can transmit DSD.

They're handled just like SACD's - HDMI and analog only. On the 103 and 105, they're converted to PCM on HDMI1.

Thanks for confirming that. No, the NAD can't accept DSD sadly so it would have be converted to PCM by the Oppo in any case.

Have you compared DSD via Analog Out of the Oppo, versus HDMI out to a suitable DAC/processor for SACD and DSD playback? Just wondering which produces the best results. I wonder how much sound quality (if any) is lost in the PCM and down sampling conversion.

Its a shame the Oppo's don't have a USB out also for non-protected DSD (i.e. DSD files rather than SACD DSD streams), though that's probably a little greedy, given how much the Oppo units can do already!

IMO, my processor, a Denon AVP-A1HDCI with the latest hardware update that provides 3D passthrough and Audyssey XT32, does an excellent job handling analog, PCM, and DSD from the Oppo. My Denon processor accepts DSD, so I've been able to try analog, DSD, and PCM - they all sound fantastic, but as usual YMMV. If at all possible, the best thing you can do is try the different combinations. Oppo has a 30 day return policy for just this purpose - all you would be out is shipping charges. If you get a BDP-105, you could try it with the NAD both ways and exchange it with Oppo for a 103 if you find no benefit from using the analog outputs on the 105. Or were you thinking of going with a 105 and connecting it directly to amps?

Did you really mean a USB output for DSD? I'm not sure what you'd use that for. The other digital outputs, other than HDMI, can't transmit DSD content due to licensing restrictions.

Cool, so you have been able to compare the varying outputs of the Oppo; so in your tests which set-up sounded the best???

Most outboard 2 channel DACs only take DSD streams via a USB input, so a USB output on a device that can play/stream downloaded DSD files would be quite useful.

IMO, there's no clear winner here and there are a lot of variables involved as Audyssey can be applied (or not) in all cases. With my system and room setup, having Audyssey enabled makes a pretty big improvement, so analog output makes the least sense as it has to be re-digitized in order to use Audyssey. But what works best for me may not be best for you. As far as DSD or PCM output from the Oppo, I quite honestly don't notice much, if any, difference there.

Gotcha. I wouldn't expect to see a USB output on something like the Oppo players. Definitely not on the 105 as the whole point of the 105 is to use the onboard DAC.

I understand "they will ALWAYS get a full range signal regardless of whether you set your speakers to large or small". But if the speakers are set to small the sub, being part of the multichannel system, will still reproduce the bass below the cutoff?

Correct - the sub is always part of the multichannel outputs regardless of how the dedicated stereo outputs are configured.

hi: iv posted on another avs oppo page and to no avail nothing helped \. im new to this audiophile world and this is my first addition, my system is philharmonis 3 speakers 85 db, emotiva xpa-2 ,oppo bdp-105,tv is 65zt-60 with xfinity cable box and internet. my question is why do i have to turn it up to 50 to start to hear it i mean it plays at 10 ,20,30,and 40, why can i turn it up to 100 and not have my ears a humming i mean it sounds good at a hundred but should i be able to turn it to 100 i called oppo and they told me its a blueray player you need to get a pre amp not anything why it wouldnt play loud just i needed a av or pre amp, wait the one reason i bought this player is all the reviews that said its sound was ok conecting st8 to a amp?im wonderring what im doing wroung cuz it has to be me, i have the oppo conected with unbalance cabels to the xpa-2 then unbalanced cabels to the philharmonic 3, the xfinity box is conected to the oppo to the tv (that it) i have the speakers set on the oppo to large with the rest turned off, what am i missing here? now in the last thread they were saying my speakers were 85db and wernt easy to drive and i was like the xpa is rated at 500 watts into 4 ohms and what does efieceisecy have anthing to do with volume plus 500 watts should be enough to push anything, there is somthing im missing its a pretty easy set up so any advice would be gratefull. another one said well we dont know how loud he like it but let me tell you the tv at a 100 is just as loud but wi the speakers cant handle it with those watts at 50 should be way more than enough but 100 sounds great my ears should not be able to handle 100 unless its 4 am and im just getting home from the club and for movies 100 is perfect no there has to be somthing wroung there plz advise tyvm for anything!

^ The absolute volume you hear from the speakers is not just a function of the output voltage of the player (i.e., its Volume setting).

There's also the input sensitivity of your amp, the gain of the amp, and the efficiency of your speakers (how much oomph they need as input in order to sound loud). And of course there's the recording level of whatever content you have chosen to play.

In the back of the OPPO manual, check the output voltage specs for the Analog outputs (they are different for the RCA and the XLR jacks).

Then in the manual for you amp, check what it is EXPECTING as input voltage, and also its Gain. Also, and this is critical, check what type of speakers the amp is designed to drive. Speaker loads are rated in Ohms, with lower numbers meaning the speakers put more load on the amp -- i.e., require more oomph from the amp. You amp may be rated for 8 ohm speakers. If you are connecting 4 ohm speakers -- or if you are trying to drive multiple speakers in parallel from the same amp output jack (which is the same as putting more load on that jack), then the amp may not have the oomph to drive them. You may need a bigger amp or more efficient speakers.

If you are using the Balanced (XLR) stereo outputs of the 105 to Balanced inputs on your amp, you may also find that your amp has switch settings on its inputs to adjust to the input voltage -- for example a switch setting to lower the volume by -6dB. Perhaps the switches are set wrong.

Get an audio calibration disc: The LPCM test tracks on AIX Audio Calibration, Blu-ray, are good for example. Also get a Sound Pressure Level (SPL) meter. The inexpensive, digital readout Sound Level Meter sold by Radio Shack is the one everyone uses. Use the calibration disc and the meter to see what sort of output levels you are actually getting.

Typical "target" levels for a Home Theater setup are 75dB SPL. See what sort of Volume setting you need to achieve that. If you are getting that at an OPPO player Volume setting of as low as 50 or 60 you are doing just fine. Your expectations for playing extra loud may be what's wrong here. (Protect your hearing!)

On the 105, each step of Volume is 1/2 dB. So going from Volume 50 to Volume 100 is +25dB.

I've been very happy with my 105 in a dedicated, treated room - running Orion 3.4 and Philharmonic 2s in 2 channel

The ipad app is buggy as of 1/13/14 but if they get that working perfect I will be SO happy

I mostly run hdtracks/sacd/cd streamed from a qnap san...dont spin discs or LPs

Yeah, since getting the Oppo I've given up on spinning discs. I'm all digital going forward.

I'm glad you mentioned the App being buggy - it keeps getting lost as to where it left off and I have to completely reboot the phone to get it back on track. I was afraid it was my phone.

I also have the Android app on my phone and tablet. On the phone it crashes as soon as it powers up the Oppo, on the tablet, it runs with a black background and black txt! So I can't see what I'm doing. Weird.

I firmly believe that digital music is going to be big this year...and I don't mean MP3 obviously, I think HD digital music is going to start gaining traction this year.

I do have a dedicated home theatre room with room treatment which is only used for movie watching. I currently have an Oppo BDP103 connected via HDMI to a Lexicon MV5 followed by an old (but Solid) Parasound HCA 1206/1000 and Jamo THX ultra II D600 speakers. What are your thoughts on benefits from upgarding to a 105 and running the analouge into the Lexicon? Again just for movie watching only!

IMO for movie watching only, it's not worth it. For critical listening via analog to CDs, SACDs, etc, IMO then yes, it's worth it. PQ will be identical between both units (unless you upgrade to a Darbee model).
