I guess this(Pop Noise while track moving to next one) is issue for all Dx80 user who use external DAC with Dx80. I know 3 guys who use Dx80 with external DAC system and they are using Dx80 Digital out (SPDIF or Digital Coaxial out). Unfortunately, they have same issue. Hope it will be fixed...

I am using Dx80 on my Car Audio system thru Digital Coaxial cable.   It seems pop noise is common issue on "Dx80 user" so far. My unit has also same behavior between music track. Sometimes, it will be between tracks or initial playing music track. Not sure it is high priory to all Dx80 users...
