As with all modern Beolab speakers the analog input (RCA or also XLR in Beolab 90) is digitized. So there you have it, an extra stage in your signal chain. I am not claiming that it will sound inferior, but it is an extra stage. I am still waiting for someone to test these marvelous speakers fed by a truly hi-end phono stage (new Nagra classic phono please?)

As for the digital inputs: As fas as I know, optical input is limited at 24bit/96kHz while USB and coaxial go up to 24bit/192kHz. All digital inputs are influenced by cable length with optical being more sensitive to low quality cables. So you have to taken into account many things, like your source material, playback device, cables etc.

I’d be much more concerned about the quality of the music, that you’d want to listen to.

There are huge differences there - and most recordings are not what one should call ‘high quality’ (regardless of the bits/kHz container they are served in).

Old recordings are analog per definition. anyway.

With the amount of processing used in modern recording, the least differences should come from the different inputs of the 50/90’s.
Those speakers were made to treat every input as equal as possible. 

It will mater much more, whether the 50/90’s are set up correctly and also play in a halfway decent room soundwise, or not.

Also consider that the sound from one particular device might be different, when you use one output instead of another.

Spend more time enjoying the music - and less on finding theoretical differences from the different inputs of the speakers....would be my 2cents.

There is a tv - and there is a BV.

So you mesn whatever signal you put in them they sound the same?

That is just bs.

Take a bad car stereo and put on som music. Then connect your phone to it with the same song. Do you hear the difference? Beovision 7-55 MK1 red, Beolab 10 red. Beolab 50, all black. Beolab 17 broken ice. Beolab transmitter. Apple tv4 and apple express 2.

Pardon me - please read my entire post and please don’t overreact.

Not talking about ‘sounding the same’ - what I said, was that it will be very hard to define, what is ‘good’ or ‘bad’ there.....

....and that there are a lot of other things in a listening chain, that might nead more attention (as eg. the quality of the recording.....again my 2Cents.

When it comes to different inputs (and outputs) peole seldom agree on what is ‘best’ - it often ends up in a hot discussion, a some time rather riligeous one .

It will be much easier to agree on that they sound ‘different’.

Why not do the test yourself - after all you are the one, who will listen to the results.

After all, I've bought a Linn streamer for use with my 50's, as it sounded better than just using a Core.

Maybe it is just that the Linn/the ouput of the Linn sounds different than the Core.....and you prefer that.

Which is totally ok - noone can say anything against that.
