It seems like some grounding problem between components. Would you provide detail information what components are in your system and how they connected together, maybe we can figure out what is the culprit.

@imhififan I have borrowed 1 DAC and 1 pair of speakers from dad to test this Accuphase amp. 

Here is what I found: 

-the pair of speakers that I borrowed has lower sensitivity so the noise is lower

-the DAC that I borrowed has lower noise than my DAC 

-if I use 2-prong power cable (the one with no ground cable) for the DAC, there is absolutely no noise from the speakers. 

My system are like this: 

-Computer (small form factor, no monitor connected) -->USB--> DAC --> Amp --> Speakers

-Computer, DAC are connected to their own power conditioner

-Amp is connected to its own power conditioner. 

 

@imhififan Thank you very much! The link is very helpful. At least now I know the cause of the issue.
