pop sound between tracks

My apologies. I'm coming very late to this conversation. I have an Aurender N200, and recently acquired the MSB Discrete DAC. With this DAC I'm experiencing a clicking / ticking sound when the sample or bit rate changes from one track to the next in the playback queue. It only happens when the sample or bit rate changes. The Aurender conduct app confirms that this can happen. So too my dealer, confirming that it happens with other DACs. I nonetheless find the clicking sound annoying. Also annoying is that the Aurender conductor app has a playback delay function to allow the DAC to adjust to the new sample rate, but that has not resolved the issue. But thanks @mlsstl very much for your post and confirming that it does happen with certain DACs.

After many months of struggling and major frustration, Aurender loaded a special firmware update on my Aurender N200. This was after my dealer replicated the issue with an N200 of his. He had extensive discussions with Aurender and conducted much testing. Thankfully now, Aurender was able to fix the problem with this special firmware update. The tick / pop is gone. So, the issue had absolutely nothing to do with my DAC, none whatsoever! It was a fault on the N200 caused by some software update.
