So let's see. SlimDevices puts in time and effort carefully engineering their product. They measure the resulting product and it looks pretty good. A writer does no measurement at all. He "knows" that a switching power supply is terrible and guess what, he finds it to be "woefully inadequate". And a cheap and cheerful linear power supply that costs $ 7 produces a "significant gain". This outcome doesn't surprise me but I think some skepticism is warranted. Some questions to ask about a replacement supply: - Does the transformer hum? - What is the level of ripple and other noise on the 5V output? - How reliable is this power supply? How good is the quality control? - Has anyone actually tested the replacement power supply to see how it performs. Has anyone tested a SB with the standard power supply against the replacement power supply? (I mean something more rigorous than just listening before and after the change and "hearing" a big difference.) High-end audio writers love to find tweaks to write about. They rave about veils being removed but a bit later, the tweak of the day is abandoned for something else. Follow their advice and you have a grab-bag of tweaks they stopped using long ago.
