Topic: Adi-2 DAC FS - AES - UA Apollo - clocking?

Hello.

I use an Adi-2 DAC FS as my monitor DA in the studio.

I have a technical question and hope someone can answer it for me :-)

Connection options are:

1. Playback on MAC -> Adi 2 DAC via USB -> listen

2. Playback on MAC -> UA Apollo -> AES Out Apollo -> SPDIF/AES in Adi 2 DAC -> listen

In both cases the ADI-2 DAC uses Steadyclock technology to reduce jitter and uses its own FS clock to perform the D/A conversion.

Now to my question:

The technical difference is that in case 1 Steady Clock FS uses the direct digital signal from the Mac.

In case 2 Steady Clock FS uses a signal that has already been clocked by the Apollo.

Is that correct?

thank you

The technical difference is that in 1) the DAC runs in clock master mode, in 2) in clock slave mode. There is no measurable difference, though.
