Performance

The small power supply which is provided with most types of equipment is based on a technology called Switch Mode. Using this technology it is possible to create small, efficient, and low cost power supplies. Unfortunately due to their method of operation (high frequency capacitor charging), these power supplies are also very noisy, causing degradation in sound quality. As an alternative, several after market power supplies exist which are usually based on Linear Regulators. These regulators provides an improvement over the original power supply but as can be seen on the graph below are still limited in their performance.

The Teddy5/3 power supply is based on a superior regulator called SuperTeddyReg and provides a significant improvement over linear regulators.

The following graph shows the noise level measurements of the original wall wart power supply (red line), an alternative power supply based on a Liner Regulator (blue line), and the Teddy12/4 power supply (black line). The brown line is a zero Volt reference which is actually the measurement equipment internal noise. As can be seen the Teddy5/3 power supply noise level is very close to the zero Volt reference.

    Ordering was a bit of a hassle because of some minor problems on the website, but after that all was well
