Oppo 83 Blu ray , who owns one?

Retro152 · August 2009

Hey guys. Boy, after reading through this thread, ya got me all excited, and i am seriously considering pulling the trigger on this unit! (thanks:rolleyes:) LOL. One question: Have never heard a SACD, night and day compared to redbook? Thanks. (Good thread Dan.:D)

In some cases yes, but like anything it varies. A good SACD or DVD A, like the lossless codecs will open up the soundstage, offer greater detail and is noticeably better than a good CD of the same material. The multi-channel mixes become addictive for some, but not all...it's a preference.

Ricardo · August 2009

Gotta love today's technology. Already added the Oppo to my Harmony one, created the "Blu Ray" activity, and set up inputs in the receiver. So when the player gets here tomorrow it's just a matter of plugging power and the HDMI cable.

For you guys that have already gone through this.....

I plan to use just HDMI, and have my receiver do all the decoding. Any tips on set up for the Oppo? And will I get SACD through HDMI, or do I need to use the analog outs for that?

Can't wait!!!

That depends on whether your receiver can decode DSD or not. If not, then the Oppo with do the DSD >>> analog decoding internally and you will then need to use the analog outs.

Ricardo · August 2009

Cool. I think the Denon 3808 does decode DSD, so it looks like I will be fine just with the HDMI.

If your receiver can't handle the DSD conversion the Oppo can convert the DSD to PCM and send it out over hdmi. You will need a receiver with hdmi v1.1 or better. HDMI v1.2a is requred for DSD transmission. Refer to pages 57 and 59 of the manual.

You know I was in the second EAP for the Oppo and didn't go for it. I currently own a Denon DVD5900 and haven't taken the plunge with Blu-Ray in my family room. I know the Oppo is supposedly fantastic and is the way to go, but I place a big value on hefty, quality construction. I have an Oppo a friend gave me for my bedroom setup and it works okay, but frankly the construction is crap and the tray could snap off if one were not really careful. Obviously Oppo puts the $$$ under the hood, but I'm so afraid should I buy one, I'd be very disappointed with the fit, finish and quality of construction. Guess It's my bias. DJ

Ricardo · August 2009

Well, even though my Denon is supposed to decode DSD, I didn't get any multi channel SACD until I changed settings in the OPPO to PCM. Then I got it, still through HDMI.

Not worth it anyway...multichannel SACD completely modifies the recording. What's supposed to be in the right channel comes from the left, and so on. I'll keep my "outdated" 2 channel for music, thanks

Now I just need a Blu Ray movie to see what this thing is capable of.

One thing I can comment about; excellent build quality, and impressive packaging. Thumbs up for OPPO.

mantis · August 2009

I actually got to Install one today. How weird is that??? Our customer purchased all Paradigm speakers and he got his gear online. The oppo was there as well as a Marantz 6003 receiver. It was ok for a mid priced receiver. I liked it's dynamic range. Nice.

The Oppo is fantastically fast. I was shocked that I pushed the open button and it a few seconds, it opened...Awesome. I love it.

Built quality is on par with any 600.00 dollar player. Nice and clean. Usb port on the front as well. It has a 7 channel analog as well as a 2 channel out for cd playback. Nice.

The menu system is clean and straight. I really like it. The remote it comes with has a back light. Good stuff if your actually going to use it.

Audio video quality is on par with everything I have Installed and owned. I think for a 500.00 player, it's well worth every cent. I'm now getting one. I'm sold.

Maybe you should try MCH with something you're not familiar with...then no expectations as to placement

Told you, you'd like it. Hate to say I told you so. Wait until you pair it up with your SC-07.

Gaara · August 2009

Well I spent almost a full day going through the threads on AVS, Audiocircle, Audioasylum, etc. and reading all the pro reviews. Pulled the trigger yesterday, ordered via amazon in the morning and its scheduled to arrive today. Sweet, traveled 300+ miles in 24hrs.

Anyway, I bought the Oppo and the BR picture is great. A big improvement over the up scaled DVD. In fact, it is so good that I can rebuy and watch my very favorite DVDs in BR, and it seems like a new movie. Throw in the fact the uncompressed sound for 5.1 LPCM over HDMI to my “old” AVR is really better than a DVD. I especially notice a better use of the rear speakers. I feel sorry for all those who skimped on their rear speakers since they felt, or were advised, rear channel sound is marginal.

Thanks for the impressions, I can't wait to finally hear the uncompressed soundtracks.

Ron Temple · August 2009

Don't know if you new owners received it with your units, but Oppo is sending out an AIX audio calibration disk/sampler for the hi rez codecs. I just got mine yesterday in the mail. Those that purchased before June 1st have received it along with blue filters for the S&M video calibration disk that was included with the players. I'm sure everyone will get this shortly. Nice job Oppo.

Gaara · August 2009

I just ordered and no AIX audio calibration, but I did order through Amazon.

Is anyone else having issues with the analog outs? I understand that the soundtrack has the LFE at -10db and that your pre generally reverses this when using digital inputs. My issue is how on earth do you do this using analog outs?

Everything I do seems to adjust the LFE and summed bass from speakers set to small. That is currently the SW out = Summed bass + -10dbLFE, if I raise the sub out I get SW out = +10db summed bass + LFE.

I have tried adjusting the sub level in my B&K Ref 50, I have tried lowering the other speakers levels, I have tried increasing the sub level in the OPPO, I have tried decreasing the other speakers levels, all to no avail. On AVS the standard fix is to increase the sub level in your pre or sub or oppo, but this does NOT fix the problem. I am doing my testing using a AVIA Calibration disc, specifically the 6ch pan that goes to LFE compared to the subwoofer level matching tracks which just focuses on bass.

Anyone have a fix which raises just the LFE not both the LFE and summed bass?

I run my SDAs large, so no bass summing going on. I did boost the gain on the sub a bit, was running the channel trim on the pre at +10 and the trim on the Oppo at +4. Calibrated the system with the AIX disk yesterday. I reduced the channel trim on the pre to +6. Watched Mutant Chronicles last night...lots of LFE...awful movie...in DTS-HD/MA. Anyway, I have a friend running his rig small with a Marantz 8300. His pre may offer BM over analog, I'm not sure. I'll ask him if he has a problem.

BTW, I've never had success calibrating with AVIA (old version) over the analog outs. Maybe, you should wait for the AIX disk. Tests include channel identification with all the offered BD formats. I had one issue, it didn't detect DTS-HD/MA. I asked Oppo about it. DTS-HD/MA is flagged as playing on all the BDs that are encoded with it that I've played, so it's got to be a bug in the disk. Also, has calibration tones for all formats, phase tests, full system sweeps w/o sub, sub sweeps and crossover/blend tests. The AIX disks will be included with new purchases and mailed to anyone that didn't get one with their unit. You're probably at the end of the line, but you might call them to get a feel when it will come to you.

Hi,
I want to share that I get the new "OPPO BDP-83 Blu-ray Disc Player w/SACD & DVD-Audio"
It is simply spectacular .... (http://www.polkaudio.com/forums/showthread.php?t=86535)

IN MY OPINION. "OPPO 83" became MY REFERENCE today. As a user of MARANTZ and DENON. OPPO do compete very satisfactory.
Impressed with Oppo. Today I made a comparison with a DVD-3800BDCI: Blu-ray. Video results: No difference. In audio, 4308Ci next to the Oppo 83, to hear angels sing. There is a marked improvement in the audio. It's my reference.
My sources have been Sony, EP-35 HD DVD Toshiba, Marantz, Denon. Oppo to get my configuration changes were marked.
After listening to several CDs encoded with the HDCD (The Doors - The Doors, Waiting for the sun, You are the One and Supertramp - Some Things Never Change) on the Oppo and the Rotel RCD-971 from a friend, we can say that There is a clear difference between the two.
The sound of the Rotel shows a somewhat more serious blunt the Oppo provides a wider sound image, clear and deep, in which there is a greater separation of instruments due to media and more detailed treble. My friend tells me that it seems that both have been equalized with a different approach, putting more emphasis on the bottom of the range sound for the Rotel and highlighting the medium and high ranges in the case of Oppo.
Once again, Oppo is my reference.

" The important thing is our ear. "

I was going to post a link to the AVS discussion on the sub/LFE issue but both Gaara and Ron are already there.

Here it is if anyone else is interested.

Thanks for the heads up on the AVIA issue, someone over on AVS posted something similar, his results don't match up with other test discs either. I'll give em a call and find out whats going on with the AIX discs, that could solve all my issues.

Ron Temple wrote: »

Not enough LFE. I did the tests with AVIA and got my sub level matching the rest of my speakers, and tested bass managment and everythings good. I did the 6ch pan test which outputs on LFE only for the sub track, and its 5-6db lower then the rest. Even if I up the sub level in the OPPO it ups the LFE and summed bass, so the overall level increases but the LFE is still 6db shy. I could up my sub by 6db so the LFE is at the right level, but then any bass below 80hz would be 6db hot.

I also tried a real world test using Black Hawk Down. I level matched the digital coax out to the analog out and tried the "Irene" scene which is has a lot of LFE. Using the coax out there was alot of bass, enough that some items vibrated in the room and I the buttkicker was shaking the couch. On the analog out at the same level the bass was more subdued, nothing resonated and I only lightly felt it.

I used to be subscribed to the AVS thread, but I stopped because I was getting my Inbox stuffed with useless post

. Anyway, I just looked back in there and you got some pretty good replies. The guy that had the BK 50 said that, basically, you're going to need a 15db offset. I know that's going to mean you're going to have to bump the sub gain, recalibrate your digital settings with everything waaaaayyy in the negative and then for analog, go +10 on the BK trim and + 5 on the Oppo (an hope you don't clip). I can't see another solution.

After running the AIX calibration, I'm actually a little hotter than I run my rig digitally. For standard DD/DTS via optical, I run the sub at 70dbs vs 75dbs for the mains (it just works, phenomenal bass when running large, LFE+Mains...I don't know why, it shouldn't but it does). With the 10db offset applied via analog, the sub is hovering at 72-73dbs, so flat. Hopefully, this disk will help you out. AVIA has some dialnorm offsets built in. I'm not sure what that does when using analog. All I know, is that I couldn't get it right when I tried it a few years ago.

The problem is if I run the sub 5db hotter then the LFE is at the correct level, but everything below 80hz is 5db hot. Right now when I do the tests at reference level my speakers are at 72db, and the summed bass is at 72db, while the LFE is only at 67db. I can increase the sub level 5db but then I have 72db for the speakers, 77db for the bass, and 72db for LFE.

The other tests I did substantiate this. Doing freq sweeps with the LFE at the correct level there is a sudden bump in the dbs at the x-over point. As described above I also did the "Irene" scene compared to the dig coax out both level matched, and there is noticeably more LFE with the dig coax, even with the speakers and bass at the same level.

As for the AIX, that will be great. At least I will have something to compare it to.

Gaara · August 2009

P.S. Sorry for messing up this thread guys, I figured some people may be having the same issues as me but now half the posts are about my problems.

On a positive note I just got off the phone with Duggin (sp?) who thinks it is a issue with the Avia disc (like Ron mentioned) and is sending me the AIX disc. He said turnaround time is 2-3 days, if you ordered from OPPO they are sending them automatically, if you ordered from Amazon give em a call.

kuntasensei · August 2009

Avia's test tones are all located in the main channels, and assume that you're using an 80Hz crossover. On a digital level, those tones are correct for a C-weighted meter (I verified this digitally by extracting the AC3 stream into its 6 channels and running a frequency analysis - 75dBC on main channels, 73dBC on subwoofer tones), but they will not work correctly unless you're using an 80Hz crossover on the main channels. The bass pans aren't really meant to be used to ensure consistent metered levels between summed bass and LFE.

As much as I like some of the stuff on Avia, that is one of its weaknesses (just like it is unusable for grayscale calibration because there's red leakage in all their grayscale patterns). Of course, Digital Video Essentials is even more useless for setting subwoofer levels, since its test tones aren't properly filtered and the LFE tone isn't pre-compensated for the +10dB boost in the LFE channel (which gives you a 6-7dB offset with C-weighting, as verified digitally by me and with ground plane testing by Ed Mullen, now with SVS).

I ended up using a software DTS encoder to make my own DTS CD with the same tones in the left main and then the LFE channel just so I could verify that everything was working correctly on my setup. It has come in very handy.

What processor are you using? I have the same issue and it can be very difficult to get the sound you want. I am running a Sunfire TGP 5, and the multi-channel path is passive, no bass management or anything. What is sent from the source is passed through. As I understand it movies have the LFE cut by 10 db and when played back the decoder is supposed to boost the 10 bd back into the sound. I hope that Oppo can work something out in a future firmware revision for those of us in this situation. I have talked to them about this also.

B&K Reference 50. No bass management on the analog input here either. My issue is that I compensated for the 10db but am still a little off.

Not sure if it is a issue with the player, the pre, or the calibration disc I am using...but I am leaning towards the disc.

Tried it and no change. My pre doesn't have bass management on the analog inputs, and it doesn't have that bug that cuts out any bass over the x-over point.

Just as a update I FINALLY got this working right, thanks to that novel of a post from Bob Pariseau on AVS.

Not sure where I went wrong but I think it was the issues with the Avia disc. I ended up using the THX Calibration from the Wall-E Blu-Ray. Tested the Irene scene again and much improved, then did War of the Worlds and it sounds as it should.
