And what you're hearing is the "handshake" between the two devices when getting back in sync.
Unfortunately, if the volume control of your preamplifier is in the digital domain then turning down the volume won't help.

I had this issue when all my music was MP3. When I got a gigantic hard drive and converted it to ALAC the issue when away. The caveat being that near after I hooked up my computer to a Audigy outboard processor and manually set the handoff over the optical connection to 44.1 out from the Mac Mini and 44.1 In at the Audigy and set the upsample to 24/96. The sound is wonderful.

I have a pair of Magnepan MMG's connected to two Emotiva mono blocks and a Emotiva preamp. I stream music from Spotify on my iPad and send it to the preamp with an Apple Airport Express which is connected to the preamp with an optical cable.

My problem is this, when I select a song to play the speakers give out a loud cracking noise before the song starts playing. There is no further cracking noise as the playlist proceeds. If however I choose another song then the loud crack sounds before the song starts.

Even if I turn the sound completely down the speakers make the cracking noise.

Does anyone know a solution for this problem?

Thanks

If your preamp has a MUTE button, use that while changing tracks.

It should ground the input to the power amplifiers and prevent the problem.

If it does not ground the input to the amplifiers when muted, it is poorly designed.

You might also eliminate the problem by using an analog audio connection to the preamp rather than digital.
