Review on IPower Noise Power Supply Adapter Computer Components for Internal Components by Tony York

Sounds fantastic and is worth the extra money compared to regular black as it produces an accurate sound without being too bass heavy. The Jameco Reliapro 2770s are good too, but if you have the extra money they have the cleanest sound, but have the same powerful bass as the blacks, but different from the usual when you really need it. I use it with Topping E30 DAC and Topping PA3 amp for E30. This power supply helps the DAC a lot but make sure you connect it to a good surge protector along with an amplifier and possibly a source to really get the best clarity out of your system. Isolated speaker and USB cables also help improve clarity.
