Oppo:


C.A.:


No question about the different power supply, not to mention the proper chassis ground on the C.A. I doubt the loaders are different.

The chassis itself is different also.

OK, so I've mocked up a quick comparision of where I think the differences are between the two PCBs are (apart from the colour of course). You may need to refer to the images above for a clearer view, without the grafitti!

Yes that is the question, with a SRP of 799 euros, that puts it into the BD 83 territory... with its better DACs and ABT chip...

Hmmm, that is actually Oppo SE territory... next try by CA, but nevertheless not as outrageous as Lexicon and there Are some differences...

It's been suggested that one might wish to compare this C.A power supply board with the one that's in the Oppo BDP-83SE. Not having done so, I can't say if there's anything to that.

According to the manuals, the 650BD only decodes DTS-HD Master Audio to LPCM at maximum of 192/24 for 2 channels via HDMI, like the Oppo BDP-83 whereas the lower spec'ed Oppo BDP-80 can output LPCM max. 192/24 5.1 channels as it should be doing.

Has anyone done the tests and verified this? Assuming the info is correct what is going on? Are the same discrepancies seen in other Mediatek based players?

Audiosceptics accept audio trials using 25 people. A recent Oxford study with over 353,000 patient records from 639 separate clinical trials shows for every 1,000 people taking diclofenac or ibuprofen there would be 3 additional heart attacks, 4 more cases of heart failure and 1 death every year.

Affecting DTS only, 5.1 output will be limited to 24/96 when decoding in the player. Bitstreaming is not effected. This is the specification for DTS-MA decoders in general AFAIK. Since all 3 players mentioned use the MTK decoders, results should be the same.

Edit: Just confirming that the BDP-80 outputs 24/96 when decoding 5.1 24/192 DTS-MA, but bitstream is 24/192.

Thanks. So much for 'bit-for-bit identical to the master' for dts.

The DTS-HD Whitepaper only says:
Quote:


DTS-HD Master Audio Features
...
Up to 192 kHz sampling frequency and 24 bits of signal resolution for 2.0 channels

which is somewhat simplistic as it is possible to encode in 192/24 5.1 as in the 2L BDs.

Generally speaking but still relevant to CA, does it have any implications for player or AVR decoding and analogue conversion, in that 192/24 5.1 is internally down-sampled first to 96/24 LPCM before entering the DAC step?

If you can hear any difference you will be the first.

Note the updated image of the C.A. back panel which shows the new location for the IR jack, directly above the Ethernet port.
Also absent the cooling grill in the original image, and the power switch.

That's it - the board is for the IR port. I looked at the Audio Advisor page for the CA this morning and there nothing on the rear panel that explained the extra board.

I have one on order and should be here in a couple more weeks. Demo in the store showed very fast load time. Can't wait to test it out.

It is hard to tell from those pics but there may be some upgraded parts on the analog audio board. The CA pic is at a weird angle with shadows. A close up pic would be nice.

The upgraded power supply might do as much good for AQ as minor mods to the audio board. I'm assuming that the power board is the same as the one in the Oppo BDP-83SE.

I find it surprising that there are not inside pics of the SE.

I don't see how you can say for certain there is or is not "minor" upgrades to the audio board just from that pic.

I'm not saying there are or are not any analog board mods. But logic dictates that given the price of this player and the existence of the upgraded power supply and IR input, it's VERY likely that there are no mods to the analog board or very minor ones. Anything more than that would demand a higher price since Cambridge would likely be doing the mods themselves. If I'm wrong, then this player might be a pretty good value at this price.

Edit: Here are some very good photos of the BDP-83SE innards. Looks to be a different power supply after all, so the Cambridge is a custom built power supply which should add even more to the price. http://www.laaudiofile.com/oppo_bdp83se.html

Yes but based off that pic you just posted it looks more like the CA has an upgraded 80 PS with no relation to the 83's PS.

That would be the logical assumption, but as I said it also pushes the price higher, so substantial audio board changes are less likely. In any case, the Cambridge is looking like more of a fair deal at the current MSRP. Details on the analog board would certainly be interesting.

One thing the Cambridge is not is an over-priced Oppo clone. Not sure why it's not getting more attention and reviews. Hopefully that might change.

Surely Home Theatre mag or even Sound & Vision might review it soon, since they have reviewed one of Cambridge's receivers in the past. Also, has anyone read about any new BD players coming from Pioneer Elite? All I"ve seen from CES news so far on Pioneer is releases about their car audio gear.

Hi All
I have installed my 650BD and must say that I am impressed with it. I have it connected to a Denon AV amp (no HDMI) so I am using optical connection. I have instead bough a true matrix HDMI hub that handles the HDMI feeds to projector or TV.

I am using KEF speakers in 5.1 (but no .1) as I have directed the base to the bottom of the KEF floor standing to give the base. The projector I am using is a DLP 1080 onto a white glass bead electric screen.

So thats the spec ('ish)......

The machine is lightening quick to load (20 seconds to display menus). Being CA the audio element is fantastic on music file as well as movies. The upscaling on DVD is also beautiful. You may read review about the tray being a little loud, and the display being a little ineffectve - who cares when you get output like this! Super quiet when running. The colour depth and image are clear.

It's a shame I can't keep updating my equipment every five minutes but I'm pretty pleased.

Even the wife, who shows no interest normally, and thinks I'm a geek at times, remarked on how good it is!

so......

HDMI and SPDIF?
Should have just got a OPPO BDP-80 and saved some money.
Suspicions are that the players are virtually identical outside of the analog audio performance.

Grasey: How is it that the tray is loud? When it opens and closes? And please be a little more specific about the on screen menus. What's wrong with them, in your opinion? I'm seriously considering this player and for the moment, you the only reviewer! Thanks!

How is the audio performance compared to CA stand alone CD player (such as Azur 640c) for 2 channel listening? IS it on par, better or way off?

We know that the player is not "virtually identical" to the Oppo. But we haven't been able to get any good photos of the analog board. Don't know if you're proficient with dissecting players and photos and such, but it would be greatly enjoyed if it's possible.

I had an Azur 640c V2 and I must say that this 650BD outperforms it sonically. It is a great CD player, and SACD and DVD Audio have never sounded this good. The BD pic is the best I've seen and DVD playback is also superb.

Did I say it's also fast :-)
