Power supply works as expected. I have connected it directly to HiFiBerry DAC+ Pro board. The sound of music is more separated. The biggest improvement is at high frequencies. Now it sound clearer and more realistic. I can recommend this product. There was one unpleasant thing. I received the product not acc. to picture. I have ordered the 1x USB + 1x DC connectors in output but 2 DC connectors in output were delivered. I had to change my cable and it is OK now.
Really good power supply and A+ seller. Thank you!
