Hi,
I have a newbie doubt on how to go about matching devices.
I recently had my chinese DAC die on me due to what i think might be a power fluctuation and i went back to my old Schiit modi multibit, feeding it directly into my tired old receiver being used as the 2.1 amp.
Well, the setup with Schiit did sound Schiit. However i wasn't sure if it was due to the Schiit DA functionality being bad or if it was due to a mismatch between the amplifier and the DAC.
I have this doubt since -
So my doubt is this -
1. Can impedance mismatch cause audio degradation ?
2. What are the electronic compatibility factors to be looked for when connecting a dac to preamp or preamp to amplifier & why do they matter?
3. Do DAC's always produce the output with the same signal strength or is it determined by its input signal ? is there a limit here? What is the spec that allows me to find this in source documentation
Thanks
Arun
Modi 2 multibit
Output Impedance: 75 ohms
Maximum Output: 2V RMS
chinese dac - xiangsheng 05B
Output Level: 2V
Output Impedance: 600 ohms
Yamaha DSP A2070
Input impedance - 150mV
ps : To be fair the source changed too from a hifiberry dac digi+ with RCA cable to to an allo digione with its own supplied BNC cable - so iam not sure if thats a factor too - the allo output went kaput too in the same event - so need to test all of these but i still wasnt sure about the impedance factor& hence the question. .

- . The chinese DAC was quite louder than Schiit to begin with. I have to turn up the reciever volume much higher to get the same audio levels when using Shiit and i wasnt sure if the extra amplification level was causing a distortion.
- Level matched, a 20$ DAC and 500$ DAC arent supposed to be audibly different as per some folks. (But in this case me, my wife and kid can hear the difference, when the setup changes even without AB-ing them - mainly with the bass levels being quite low and overall music being grating)
