Thats awesome to hear then. I just wanted a minimalist signal chain for 2 channel and HT if I could. This new Oppo is awesome.

Did anyone ever say if the volume increments were 1.5db per click or less?

2.0 dB per click

...

I just measured this with a dual channel scope (input impedance 1 Megohm) using sine waves at full amplitude from 1 Hz to 30 Hz at 24bit/96kHz played back via USB media. The output voltage from BDP-95 stereo outs is absolutely flat down to 1 Hz (probably DC coupled circuit from D/A and through opamp output driver) .. negligible low frequency rolloff.

Checked with 1 kohm load and same result. Also checked with sine wave at 0.1 Hz (a period of 10 seconds) and the output voltage tracks perfectly so the output is definitely DC coupled ... analog output response extends down to DC apparently for the dedicated stereo outs!

Hi all, Love my Oppo BDP-95! I was wondering if any of you are having a similar issue to the one I'm having. I am trying to figure out how to play files from computer connected drives through my 5.1 home theatre system. Here is my setup:

1) Oppo BDP 95
2) Onkyo TX-NR609 receiver
3) Knoll power amp

I currently connect laptop to receiver via hdmi and have the cables running from 2locations for convenience. Playing discs or USB drive through the oppo is far superior sound than through the onkyo directly. But I need to have the computer to receiver connection setup on par with the oppo dac sound quality for flexibility and convenience.

So I am wondering what dac/amp/other solution will allow me to connect via HDMI from laptop and play flac files etc with excellent sound quality like im getting through the SABRE32 Reference ES9018 dacs. Do you know what is a good solution? would connection be laptop hdmi -> dac hdmi input -> dac output -> onkyo recever (?)

Appreciate any advice on this and any manufacturer names. This is really important becausee the ESS SABRE dacs blow away the onkyo dac and just cant connect directly anymore to receiver and have to always go through the oppo but its not convenient all the time. I am set up via hdmi from 2 locations in my house to just plug in with laptop and connected external drive to play through system but have to enhance the audio sound quality to a high level.

Anyone have same issue? What is/was your solution? Excited about continuing my build on a oppo type level. Hope I explained that right. Thank you in Adavnce.

no i like to hard connect evrything. I have all my equipment networked through an 8 port switch. I have a wireless router but just use that as backup for guests and wireless printer, and my blackberry. Good you brought that up though. I should play with that to test it out but don't see that as a 100% reliable soution. Actually i did mess with it a little one night and all the folders werent displaying properly. I have over 2 TB's of music. I will check it out again but tho. Thanks

Foobar (with Upnp plugin) --> DLNA (wired ethernet) ---> OPPO is very reliable and can handle flac/wav perfectly.

Question: when you HDMI from your laptop to the receiver, does your laptop downsample before sending over HDMI? if you use foobar for this, you need to add and configure the WASAPI output support to ensure the HDMI exactly streams the original wav format.

The 100 ohm output resistor is capacitance isolation and current limit (similar to OPPO stereo outs).

Thanks for your work on the XLR HP box, I will first try R1=500 with my Sony EX85LP - output up to 97.3 dbSPL, which is very close to 96 dbSPL for ER4s, if Sony is loud enough for me, then there is no need to make the more complex XLR HP box for 95, unless it sounds better. Those people have even less efficient HP should be interested. BTW, warning still pop up from your table, when the load resistance is = 500 Ohms.

i'm using media monkey but was gonna check out foobar because they actually give you data readout when you normalize tracks/volume level. I dont see that in media monkey. I'm not sure if im downsampling in media monkey. I'll research WASAPI support for that. Thanks

I tried to get Windows Media Player to stream flac and finally gave up and installed Foobar. It seems to be working well. I had hoped WMP would work since I use it to stream video content and the streaming server runs as a service without the program running.

Thanks!

I strongly recommend the Silver Serpent Anniversary Edition Audio Cable from Better Cables. An excellent value.

Quote:


Stranded-core silver-coated conductors.
Low 17.3 pF/ft capacitance.
Nitrogen-injected hard-cell insulation.
95% braided shielding.
Highly flexible.
The hybrid construction gives all of the sonic benefits of silver (dynamic high frequencies) and all of the sonic benefits of copper (deep, tight bass response). The combination of silver, low-attenuation, and top-notch quality insulation makes this a world-class audio cable with no equal at ANY PRICE

Hey all,
I was wondering did anyone else experience no response from the Pure Audio button on the remote,
it's happened to me twice in the last week, when listening to FLAC files from a HDD, after about an hour or so,
the Pure Audio button stops functioning, so basically when navigating the Music menu between albums,
the screen stays on, as the pure audio refuses to work until the unit is rebooted. I'm on the latest European firmware release.
Also has anyone come across a CD that plays back with distortion, but works alright on other players.
I received a new CD last Friday which I tested on two different Oppo 95s, both playing it back with heavy distortion.
I ripped the disc to FLAC with EAC and it played back perfectly as separate files.
I also ripped the disc to ISO and burned it to CDR and it also played back normally.
Maybe the player just has a disliking to certain brands of CD media ?
Any help appreciated, cheers.

Yes, I designed that into the script ... just a gentle warning that you are drawing significant current from the outputs. The web page discusses this.

Using the unbalanced single-sided XLR (as you have wired) is fine. You can probably push the output current more with the XLR because the chip has an even higher current limit (~ 80 mA according to the spec).

A question for the experienced users:

Bass Management
I have all speakers set to small with sub on. It seems that the LFE is not the same level as bass frequencies that are crossed at 80hz.

I know there are variables, but is there a known issue with setting the fronts to small? I know with the 83SE it was recommended to set fronts to large.

WMP doesn't handle flac at all and with WMP it is hard to figure out exactly what it is transcoding to (MP3 is what it prefers in most cases). Foobar is definitely much better for DLNA streaming of audio.

I was able to add a codec to play flac with WMP but it would not stream. That said, I am getting used to Foobar and think I will be happy with it long term.

Sure I'll have too download everything from the computer*; yet just want something too feed the 95 audio files.
I could be talked into video files as well.

BIG thanks!

What firmware version do you have in the player and what sort of content are you playing when you find this problem? The latest official firmware is the 0917 firmware. Check Setup > Device Setup > Firmware Information. The correct version numbers are on Oppo's support page or in the firmware history section of the first post of the 93 sticky thread at the top of this Forum.

As far as I know, LFE is properly balanced with the steered bass output on the multi-channel Analog subwoofer output for all content types. (No bass steering happens on the HDMI output, so the HDMI LFE channel only carries LFE -- i.e., all speakers are "Large" on HDMI. HDMI bass steering happens in your HDMI AVR.)

The multi-channel Analog subwoofer output needs to be boosted +15dB to match the other Analog channels. This can be done at the volume knob of the sub, but +10dB of boost is usually applied automatically, by default in AVRs, so usually only +5dB more is still needed.

You can check levels (LFE compared to main channels) using an audio calibration disc such as with the LPCM tracks from the AIX Audio Calibration Blu-ray or tracks 43-48 from "Stay in Tune with PentaTone", SACD.

You can check that steered bass levels match the rest of the content level on the fronts for example by using the Crossover test from AIX, which sends a tone to the fronts that sweeps back and forth across the Crossover region. If the volume stays constant then steered bass is good, and if LFE also matches from the test above then everything is good.

NOTE: If the volume varies as the Crossover test tone swings back and forth this can be due to an incorrect choice of Crossover frequency, or to frequency variations in bass response in your listening room -- typically fixed by repositioning the sub or adding acoustic bass treatments to the room. AIX also includes a wider range bass sweep to help reveal room response problems.

I have notified Oppo here in Europe, who as usual are quick off the mark and have ordered the CD for testing.
I was really just wondering has anyone else ever experienced this with a CD, or is this the first CD to cause this problem.
BTW the problem disc is Ennio Morricone - La Banchiera (Expanded) GDM 2011.

I'm more concerned about the 'Pure Audio' function not responding on the remote, even though its only happened twice ;-)
post #6171 of 11017
I don't think we've had any other reports here of the Pure button unresponsiveness -- except of course when using apps like Netflix which seize control of the user interface.

Am I correct that this only happens to you when playing FLAC? Is that via DLNA or from a directly attached hard drive?

Are you sure you were pressing the correct button on the remote? It is easy to confuse the discrete ON button with the Pure button.

Also, ANY time you have remote weirdness, the FIRST thing to do is replace the batteries.

post #6172 of 11017
OPPO have confirmed that all the analog outputs of the BDP-95 (Dedicated St, MC, XLR) are DC coupled. This means that the "audio" response extends right down to DC .. which of course means that you can listen to AC/DC
even though the performance is only spec'd from 20 Hz to 96 kHz.

Although obviously not intended for this, it means that you could in principle control external "devices" which require a small DC voltage (up to about 3 VDC) if they require only small amounts of current (<~ 10 mA) ... for example high-radiance red or green LEDs. It is easy to create wav files with fixed DC amplitude. I'm not familiar with really high-end modern receivers/amplifiers but are most of those AC coupled with a LF rolloff at ~ 5 - 10 Hz?

Thanks for the input. I recently sold my AIX disc with my 83SE. I'll see what else I have to play around with. I do have the latest firmware. I'm glad to hear no reports in issues with internal bass management in the Oppo. I"ll play with my crossover setting and go from there.

Most avrs after say the mid 70's have dc coupled output stages neutron ;it helps reduce coupling cap costs as well as for other ''sound'' reasons -sorry for that one Macintosh at one stage had switchable ac/dc output stages[more correctly dc capable as an input capacitor was used] but rare these days afaik.

I sometimes wonder if the risk of dc frying speaker voice coils is worth the simplified circuit path though

Many power output stages of modern amplifiers have some sort of protection right before the speaker outputs (like fuses in emitter stages of power transistors, as one example). I was thinking more in terms of how the INPUTS to receivers/amplifiers are coupled ... I believe most are AC coupled.

I struggled a bit with LFE level when I got the 95. Unfortunately most AVR's don't provide a way to boost LFE only on the analog inputs. Turning the knob on the sub or adjusting the level of LFE in the AVR are global settings. That means if you still use 5.1 digital sources, the LFE channel will likely be 15 dB too hot for them. Of course this is a limitation of the AVR itself and not the 95. I was able to strike a reasonable balance by working with the oppo trim settings on each channel and the input level trims in my AVR. The next time I am in the market for an AVR, I will not only need pure direct MC analog inputs but separate LFE adjustments for MC analog.
post #6177 of 11017
Usually, most AVRs don't apply speaker output volume trims to their multi-channel analog inputs. Only to their digital inputs.

For that type of AVR you can boost the volume knob on the sub +5dB or +15dB (depending on whether the AVR already provides the standard +10dB boost on multi-channel Analog LFE input), and then compensate by LOWERING the sub output volume trim for your digital Sources. The trims in the OPPO would stay at 0dB in this scenario.

Just a tad

Some power amps, like the aussie me550, offered the option of switching this cap in or out of the circuit. Why have this capability? Well, the marketing blurbs claimed that _full_ DC coupling enhanced the phase linearity, more solid bass response, etc.Doesnt answer the config of the preamp stage but if the ac coupling cap was there it makes a mockery of the blurb perhaps?

Makes the oppo>power amp option look even better

Not in my case. I have a Yamaha RX-V1800, which I really like. If I adjust speaker level volume trims, it is global for all inputs, including MC analog. That is even true in "Pure Direct" mode which bypasses all EQ, DSP, and video processing. The manual says that MC analog inputs are always pure direct anyway, which I have confirmed to be correct.

Yet MORE marks for the 95
And regarding ultra-low frequency response, let's not forget that in a few years, with full inner-ear reconstruction and bio-engineering, we will have ears which can ACTUALLY hear down to 1 Hz .. wiiiiiiiish ~ woooosh!
