MiniTeddy 7V / 2A

 The MiniTeddy7/2 power supply can be used to replace the small AC plug-in power adaptor that comes with many audio equipment, and provides significant improvement in sound quality. Popular use cases are Sonore products (OpticalRendu, MicroRendu, UltraRendu), which run perfectly with the Teddy7V supply.

Update 09/24: we have released the new and markedly improved MiniTeddy Special Edition, see here: LINK

Note: For Uptone EtherRegen, we recommend on our 12V-2A power supply.

The design is based on the experience gained with the TeddyCap family of power supplies for Naim Audio equipment, and uses the same technology.

Sound

In general, you’ll experience more clarity, tighter bass, more detail, better dynamics, natural voices, better soundstage etc.

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 MiniTeddy7/2 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 MiniTeddy7/2 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 MiniTeddy7/2 power supply noise level is very close to the zero Volt reference.

Interconnects

The MiniTeddy7/2 power supply is equipped with a high quality multistrand, twisted pair copper interconnect. It has a 2-pin female plug for the power supply end and a barrel plug on the other end.
