Hello, it's my first post on ASR!
I've had a D90 in my system for a while, always used in dac mode as my power amp (IOM 250) has a volume controller.
In anticipation of my new power amp with no volume controller, I decide to give the pre-amp mode a go.
With the d90 in pre-amp mode and the amp on full volume, I can hear a loud pop coming through the speakers whenever the dac changes sample rate, when pausing/play music and weirdly enough also when muting the dac via remote.
Initially I thought the problem was the sending device/usb cable but the fact the it pops also when muting the dac with no source connected, makes me think it might be something else?
The pop noise is loud and lessen as I turn the amp volume down, the dac volume doesn't affect the loudness of the pop whatsoever, I'm saying this because Topping support told me to raise the volume on the dac to cure the problem.
I don't know what to think, I wonder if the problem is related to the power amp having a volume controller? or maybe the dac is faulty? Any advice or suggestions would be gratefully received.
thanks!
