Excellent product – does exactly what it says and effectively turns any switching power supply into an iFi regulated power supply. Useful for when a device has power requirements not met by the standard iFi power supplies eg Pro-Ject audio S2 stream box ultra and Tube Box S2. Obviously, if you think power supply regulation makes no difference, then you will not be interested in this product!
However, if you have enough common sense to understand that a clean DC power supply is essential for audio products, then this is a solution and less expensive than buying dedicated linear power supplies (usually in excess of £300). Given the range of voltage/amps this product can handle, it’s a very useful device. I have found that the adapters fit all Pro-Ject audio devices.
