Post Subject: I can not measure DCPosted by Amir on: 3/4/2023
When I use Pure Power then I hear no noise/buzz from Big transformers of Power amplifier.It seemd Pure Power 3000 blocks DC .I have no device for measuring DC voltage of AC line.I did not use any DC blocker before Pure Power and I have no idea about it but I doubt DC blocker could help without adding negative effect on the sound.I have used Isolasion transformer before Pure Power and You know Isolation transformer can block DC but isolation transformer does not help and degrades the sound.All AC power devices I have tried were not good for sound.
This is my conclusion :If you have low power system go for : AC panel -> Good AC Cable -> Pure Power 3000 -> Audio SystemIf you have high power system go for : AC panel -> Good AC Cable -> Audio System
No AC filter No isolation device EMI filter No thing . Even many expensive audiophile AC cables degrade the sound.
