It buffers a portion of the song as it plays it. So there is never a problem associated to buffer underunning.

I know this has come up before esp in the older threads but I always just skipped it since I wasn't remotely interested in doing it but is the whole skipping the AVR and using power amps a logical solution? I know it's doable but does it make sense?

I basically have 2 systems going on in one. I have my OPPO sending PCM to my Marantz AVR for home theater and I enjoy the sound (much better than my previous all Sony system). I have the analog outputs (2 channel) of the oppo going to a preamp for music only listening - speakers and headphones. I'm actually about to order a new 2-channel power amp for my 2-channel/music side of things (maybe tomorrow) but maybe I should think about moving up to a multi-Chanel power amp instead and have the potential to skip the AVR? I think the older OPPO's are a little too slow in response to use it as a volume control but I'm getting the new ones are quicker and for movies only, you're really not changing volume all that much... I'm guessing you can just take the setting from the auto room management of the AVR and add them into the OPPO settings?

Does this bypass the volume controls on the 4520? If not, it is not just using the AVR as a power amp.

Exactly.

I intend to do much the same thing with my system shortly after my 105 arrives. I had contacted Oppo a few months ago to ask about using my OPPO 83 analog 7.1 outputs to directly drive my NAD T973 power amplifier for 7 channel surround, and at that time learned about the forthcoming 105 with external inputs and DAC access. Needless to say I signed up asap and have been catching up with OPPO forums ever since. The tech assured me it would work fine. I was only concerned about impedance loading, as I was sure voltage drive was not an issue. As long as I always reduce the OPPO volume before turning on the big amp I do not expect any adverse issues, and it is only logical (and I fully expect) that bypassing the otherwise very good T163 preamp controller front end should provide additional clarity and resolution. Like we all (and Sam Tellig) know, there is no preamp like no preamp, if we can get away with it. I have done this with the OPPO for smaller stereo amps under 100wpc, but not yet with the big 7 channel amp. In my case the 105 will also process my direct sat TV, async USB digital files, and will even process the digital output from the T163, with any other inputs it has connected. For me that is a win-win solution if it functions as expected. If level adjustments on the fly are not practical in real time, I am not out much for having tried it. Plus I look forward to trying out the bonus headphone amp!

That is correct and applies to all AVRs. But the Nad series have an option where the AVR's preamp output is physically connected to the power amp input via jumper connectors in the back. If one takes out these connectors and connects the RCA plugs into the power amp inputs it bypasses the preamp section of the AVR altogether. Then one has to be careful with the volume on the audio source.

my question is, what happens to the subwoofer volume settings and adjustments with the oppo between stereo and multichannel going directly into the power amp and subwoofer from the Oppo given the default sub woofer channel trims that happen with multichannel.

Also, as posted earlier in the "what features would you like in you future Oppo player" thread", would'nt it be great if Oppo added auto room correction and EQ to the player in some way(internally or externally) now that we can bypass the preamp?

I want to do the exact same thing as bobcfla, i.e. taking out the Pre-Amp/Power-Amp connectors on my SR9600 and plug the analog outs of the Oppo into the power amp slots.

I did this before with the 95, but with the 95 you just can use the oppo since it has no HDMI or DAC inputs. Volume can be controlled with the variable analog out of the Oppo.
Works without any problem.

The new 105 gives me the flexibility to connect all my other sources.
The big questions for me is the use of the Oppo as the pre-amp and skipping the pre-amp of the SR9600 the better sounding solution (theoretically? in real life?).
This would be a main motivation to upgrade from the 95 to the 105

Did you hear an improvement when bypassing the preamp with the 95?
post #2138 of 2827
I thought that I would, but since I couldn't do a blind test, I would call the listening results subjective.

I assume, if somebody else would have done the replugging and I went out of the room for 2 minutes,
the success rate of identifying the setup would not have been a 100%

Audio Delay was allowed in the BDP-8x series of players as OPPO was using the extra frame buffer memory to store the delay information. This memory does not exist in the BDP-9x or BDP-10x series of players.
OPPO did try adding Audio Delay in the BDP-10x during the beta testing, but the results were pretty disastrous, so it was removed from the final production firmware. Perhaps it will be re-introduced into a future firmware release.

That is unfortunate. My HDMI passes through a video processor and onto the projector which all add some delay that cannot be compensated for without an A/V sync delay of some sort on the Oppo. I was really hoping this would be there this time. The fact that Oppo tried to implement it suggests it is possible so I hope Oppo give this further consideration and effort.
post #2140 of 2827
Wow, I didn't realise so many people in here are looking to try out the 105's preamp capabilities smile.gif

I have just put up my trusted old Linn pre/pro for sale. It doesn't have an analogue 5.1 in group, so I wouldn't be able to hear the new lossless formats from the Oppo.

Right now that sale is going to finance the Oppo 105 leaving me with only power amplifiers in the house, so like others here I'm really keen on hearing from the beta testers how the 105 fares as a multichannel preamp. In real life.
Bob, you have an Anthem, right? It would be really something to hear, whether the Oppo 105 can compete.

I know, I won't be getting Audessey corrections, but that is not important for me.

I just received my BDP-103 yesterday which I bought in order to get 3D with the new 70" Elite that I will get on Saturday. I knew going in that the 103 does not support Hulu Plus and neither does the TV. I watch Hulu on my 2 year old 60" Sony along with Netflix. My friend has a $100 Samsung Blu Ray player that just had a firmware upgrade that gave him Hulu. Any chance Oppo will have an upgrade to allow Hulu streaming? I would prefer not to have to buy another box like a Roku or something just to get Hulu. Thanks.

The answer to all "is there a chance?" for new internet services questions is "yes, there is a chance" but no one knows how likely or when.

A feature of the BDP-103 is that it supports the Roku Streaming Stick. Doesn't that have Hulu?

post #2143 of 2827
Was not aware of a Roku streaming stick. I had only looked at the boxes. That would be cool if it does. I will look in to it. Thanks.
post #2144 of 2827
Ordered mine yesterday.... cannot wait for this to show up, just sold my 83... The support given though out this thread made my decision to upgrade!
post #2145 of 2827
Regard running direct into the power amp, I highly recommend it! This way there is no additional A/D D/A that can take place in an AVR for volume/tone control or any other analog degradation or coloring of the sound. Having an unnecessary pre-amp in the chain, since the Oppo has a vol control, would only do this.

I had my Oppo BDP-95 connected directly to a 5 channel Outlaw 7500 200w/ch and it's fantastic. I also had my sub hooked directly to it. The Outlaw 7500 has XLR inputs too! I use those for the front two channels out of the Oppo as well as RCAs for the other 3.

In the UK, one of the resellers I'm tracking, Audiocom International, has now also joined the November bandwagon for the BDP-105EU:

http://www.audiocominternational.com/blu-ray-players/120-oppo-bdp-105eu-region-free-zone-b.html

They are now quoting, "Pre-order for November 15th".

post #2147 of 2827
OPPO UK has now posted the Windows 7 / Windows XP driver for connecting to the Asynchronous USB DAC Input of the BDP-105EU:

http://oppo-bluray.co.uk/customer-services/downloads/

NOTE FOR MAC USERS: You don't need any driver to be installed for this. Use of that Input on the 105 and 105EU with Mac OS X 10.8.2 is "plug and play".

CAUTION 1: This driver may not be compatible with Windows 8. We'll need to get some clarification on that.

CAUTION 2: I'm not CERTAIN this driver will also work with the North American model BDP-105 players. I know of no reason why it shouldn't work, but it would be safer to wait for the driver to show up on the OPPO Digital web site here in the US.
--Bob
post #2148 of 2827
Thanks Bob. Can you use the OPPO to play non high-res files without loading a driver or do you always need a driver with windows?

Driver helps for asynchronous USB, otherwise you are just using the player as a standard USB soundcard.

How do you do this, I would love to try it? I am assuming you plug in the RCAs from the Oppo to the amps, and use HDMi for video? Analogue from Oppo.

Well if you use HDMi to the pre/pro theres also no additional A/D D/A since it is digital comming from HDMi

Maybe the Oppo BDP-115 will have Audyssey Multi EQ XT64 in 2014 biggrin.gif Then I can put my SSP-800 on ebay smile.gif

That is correct. You would direct connect to the amplifier with analog then use the volume, Channel Trim, and Channel Distances to properly align your audio and use HDMI for video direct to the display.

If HDMI is available you are almost always better off using HDMI versus analog unless you will be primarily listening to stereo sources.
post #2153 of 2827
I'm new to OPPO products and was considering 103 mainly for BD playback. However, after looking at 105 I thought that since it has a superb DAC in it then maybe if makes sense to buy 105 and use it as DAC for my Sonos digital music as well. But the question is, can I do that? On pictures I do see that it has digital in, but wasn't sure if this is possible or in general if paying $700 difference buys me a DAC that is equal to other DACs that cost around $1000?
post #2154 of 2827
I looks like 105 can be used as external DAC. But the question is, how is it compared to Benchmark - DAC-1 (at $1000) or Cambridge Audio DacMagic Plus (at $600)

What is the difference between standard and async USB? Is the player capable of both?

Oppo can only do asynchronous USB

Asynchronous USB Advantage
The theory behind asynchronous USB is that when a computer is transmitting data via USB to another device, the computer determines the data rate parameters. The theoretical consequence of using a standard USB interface is that it is impossible to guarantee accurate data transfer, because the computer will alter the data rate to suit its internal workload. With asynchronous USB, however, the receiving USB controls the computer’s data rate. Jitter and data compression just will not happen. The asynchronous USB interface instructs the computer that it has priority on the computer resource allocation, thus guaranteeing a continuous high resolution data stream.

do we know that the 105 has a notably good XTAL to handle the asynch timing?

Unless the pre/pro in question has an inferior D/A performance compared to the Oppo...
post #2159 of 2827
Do we know what the Oppo's max bitrate is for wireless connections to NAS/media servers?

The Apple TV and iPad are (very) limited at only 2.5 Mbps, making HD videos look more like DVD...
post #2160 of 2827
^ One real world test is the Network Speed Test in the VUDU app. In my Wifi setup, that test is pegged continuously at the top of its range (i.e., indicating some unknown speed greater than 9Mbps).

So the Wifi networking performance in the player is certainly greater than that. And that's even including going out on the Internet!

As for streaming over your in-house network, both Ethernet, and the 802.11n Wifi in the player are not likely to be the bottlenecks. Router, Wifi base station, and server configuration are the more likely bottlenecks.
