 "The BV11 won't accept 88.2 or 176.4 kHz signals"

"The Beolab 5 are limited to 88.2 khz". First ones apparently did 96 kHz.

"BS5E does play 96kHz 24bit FLAC (no sound with 192kHz)".

"BS5 plays 192kHz 24bit FLAC"

My head is spinning

And which role does the DSP's play in this matter?

Different development sections not talking to another, no real interest for highres audio or just a random purchase of DACs....?

Or am I missing something?

Hi Millemissen,

I have a pair of Beolab 5 from year 2009 and a BS5/BM5. I have connected directly with SPDIF-cable from BM5 to Beolab 5 and have played Hi-rez FLAC-files with 24-bit 96 khz. So the Lab 5 from 2009 accept 96 khz. I have also tried a FLAC-file with 192 khz but then there were no sound.

The tecnical specifications for the LAB 5 says up to 88,2 khz. But they CAN accept 96 khz. I have the latest software in my LAB 5 which is 3.2.

Regards
Martin S

Hi again,

Just a question about Beovision 11. Do you mean that the soundmodule in this TV just support up to 48 khz in sampling?

In that case it is really bad, because Beosystem 3-based TV:s support upp to 96 khz. Am I right?

I confirm what Martin is saying.

I have a BS5/BM5 combo from 2011 and a pair of BeoLab 5 from this year. You can play high-res files up to 96 KHz/24-bit, but there will be no sound if you try to play 192 KHz files.

The BV11 supports 96 kHz according to Geoff Martin - (or at least accept it).

@ Martin & Vantage.

The DSP's in the BL5's are probably downconverting to 88.2 kHz before the DAC's are converting to analog.

And also 192kHz 24bit stereo PCM input

and 96kHz 24bit 7.1 PCM input

Maybe B&O should support the Cambridge Blurayplayer instead of the OPPO....

...advice people to let it upsample to 24/96 - and organize a replacement for those who have already bought the OPPO

I guess, what Millemissen means is just, that those who can not hear the difference between MP3 and hi-res,  does not have to waste their time on this thread. And they do not have to make comments like: 'I can't tell the difference...' etc.
That debate has been going on in several other threads

Hi Steffen,

exacly - I wanted to keep THAT debate out of this thread - if possible

But I do think that Jeff did understand that too.

You do know that  Cambridge's top models blu ray player is built on Oppo right*?

But just so I understand it quite right. You Want example an oppo-103 owner to swap it out with a Cambrigde?

I'll have the OPPO-103 with my Bv8-40 and it isan amazing machine and i love it...Especially after the latest update.

But eny way

Hi situation,

OF COURSE I do know that the CA's are built on the OPPO's - they almost always were!

What makes the CA's different is the audio section. Cambridge - again as always - uses different DAC's (look for further info at their website) which includes upsampling to max 192 kHz for ALL audio content.

The OPPO's does not upsample and outputs in 88.2/176.4 kHz if native.

The 'new engine' in the V1/BV11/BSys3 does not support this - the BV7/BSys3 and your BV8-40 (and mine) does.

That was my point:

Either Bang & Olufsen gets this mess straightened out through a SW update or a new DAC in the newer video products....

....or we will have to use the upsampling facility of the CA instead of using the OPPO

NOTE: not every one will have this problem - it is only if you are trying to/wanting to play content in 88.2/176.4 kHz such as SACD or highres audio files!

Just to your understanding.

Eny way - OPPO 103 is the king!

And the CA 752 too

how much can your and my BV8-40 take? For example 24bit 192kHz is that something it can take? and when I play a bluray on my oppo and it's DTS-HD Master Audio or Dolby True-HD what bit en Khz do i then get? 

And now as we speak im hear one of my K2HD CDs with Mariah Carey and its say's placed under Features one the website that it is 24bit and 100kHz. but on the screen it says 16bit 44.1kHz instead? Why?

96khz works well on mine. But since I rip CD's, I feed them 16bit at 44,1khz.  They seem to like that just fine. And me too.

The original master may be 24/100 or some such, but if it's delivered on a CD what you have is 16/44.1, that's what all CDs are. The only physical discs that are higher are SACD, DVD-A, and BluRay audio.

A BV8-40 (or any BV) does not support HD sound formats played ad bitstream from the OPPO.

You must let the OPPO do the decoding (to LPCM) first - otherweise the BV-40 will reencode the audio to DD before decoding to analog.

The HD formats supports a maximum of 192 kHz sampling frequency and 24-bit depth samples from 2 to 5.1 channels, and 96 kHz/24bit resolution up to 7.1 channels.

Since the BV-40 'only' supports 5.1 channels the maximum you will get is 24/96.

The BV8-40 has no problems with a LPCM stream in 24/96.

Where do you get those hi-res files? Not from CDs, I assume?

I'm sure there was a thread some time ago listing sources  but you can definitely buy them form Linn, Naim or B&W websites.

Ah, ok, thanks. Anyway, I dont have anything to play them with. Just poped in mind.

I do have had issues with some digital setups, so I haven't pay too much attention to the area...

The 'sound' from a SACD when decoded by the player to PCM is also 'highres'.

And the HD soundformats on bluraydisc are.

There are Pure Audio bluraydisc too - the 'Les Miserablés Soundtrack' from Bang & Olufsen is an example. They are quite interesting because of the multichannel option.

Some people like to 'rip' (or rather digitze) their vinyl to 'highres' instead of 16/44.1 (CD/redbook format).

Hmm... There is a audable difference between hi-res and "nornal" ripping?

I have couple strange CD's (performers) that just wont play throught computer (CD-drive-soundcard-amp-speakers), don't know why. I tought it is something "resonation" between music and DAC speed, or something like that... ?? With normal player (CD4500) they are ok.

Ah, if I rip themfrom CD, they wont play even then.

Hard to tell about your 'strange CD's'

Ripping from a normal Cd to higher res that the CD-format (16/44.1) makes no sense.

Some people think that upsampling to e.g. 192 kHz when playing back via a capable DAC will make things better .

In general highres only makes sense if you have a high resolution source as master, and encode into e.g. 24/96.

That is what Linn, HighResAudio and co...... does ---- or at least are supposed to do ;-)

Yeah, you either get perfection up sampled to perfection, or crap up sampled to still be crap, depending on your views on the adequacy of 16/44.1.

Ah, I ripped them just to "normal" wav and ogg... So 44.1 only. I see there is no idea to over-rip.

I have been listening to high res studio masters since launch,on my linn klimax system,that is the reason I chose it over lab 5 setup for my dedicated music room.I have always went with the linn philosophy of 'source first' rubbish in,rubbish out.

B&o really need a new flagship system,as this is the way it's going,even if you just listen to cd quality it's good to know its future proof.
