AIYIMA sells this 3205000 power supply with many of its amplifier models.
In AIYIMA A07 TPA3255 Review (Amplifier), 3205000 seemed to have quite a bit of mains hum.
In AIYIMA A05 Review (Budget Amplifier), I couldn't see much mains hum from 3205000.
Can I assume that 3205000 has quality control issues or that amir got a better unit of 3205000 for the review of AIYIMA A05?
Has anyone measured noise from 3205000?
