Hi,

I am trying to connect my iphone to Beomaster 7000. Before that, I would like to know if the DAC in Beomaster can handle 24bits/192khz as I understand now songs bought from iTunes are 24bits?

Many thanks for your help!

Beomaster 7000 doesn't have a "DAC" in it at all. It's just plain old analog inputs.

To connect your iPhone you need a 3.5mm Stereo minijack to DIN cable, such as this one from Sounds Heavenly... http://soundsheavenly.com/apple/86--trs-5pd-.html 

There is no digital data transfer in that cable. Purely analog playing straight from the DAC in the phone. 

many thanks. I will buy the cable!

That would be new to me.

Source of information, please?

The iTunes store uses 256 kbps AAC compression, which doesn't have a bit depth.

Bit depth refers to the number of 1s or 0s used to encode the difference between the loudest and quietest possible sounds in a 'standard PCM' audio stream. As AAC uses all sorts of clever compression systems to reduce data-size, there is no bit depth.

You may be confusing this with Mastered for iTunes, which is when a mastering engineer (the final person to attend to or modify a recording before it is released to the public) will follow a set of guidelines laid down by Apple, one of which is to submit a 24 bit audio file to the iTunes store, as opposed to a 16 bit 'CD quality' file.

This makes the AAC encoding better, but ultimately an iPhone or iPad is still going to turn it back into 16 bit audio at the end of the day.
