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

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.

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

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

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.

Any suggestions on good interconnect cables to use that don't cost another arm and leg (since I already paid an arm and a leg for this player)? Obviously I'll need to buy three pairs of 'em.

Thanks!

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

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.

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.

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

(getting off BDP-95 topic a bit )

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
