Teddy7/3 – 7V 3A Power Supply
The Teddy7/3 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. A typical use case is Uptone EtherRegen, which runs perfectly with the Teddy7V 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.
The Teddy7/3 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 Uptone EtherRegen and many of Sonore products, which run perfectly with the Teddy7V supply.
In general, you’ll experience more clarity, tighter bass, more detail, better dynamics, natural voices, better soundstage etc.
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 Teddy7/3 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 Teddy7/3 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 Teddy7/3 power supply noise level is very close to the zero Volt reference.

The Teddy7/3 power supply is equipped with a high quality cable made of silver plated PTFE insulated wires. The cable capacitance is around 13pF/ft, and its resistance is also very low, around 10 milliohm/ft.
A message from a happy customer:
I swapped out my previous LPS for the Sonore ultraRendu endpoint shortly after the Teddy Pardo units arrived. I realized one hour was too early to judge the Teddy7/2 (allowing this LPS to fill/stabilize capacitors). Still, I immediately noticed better layering and detail retrieval than the previous LPS powering my Sonore ultraRendu. The sonic effects improved noticeably every day after, but the significant improvement occurred after ~ 140 hours. It didn't change the sonic signature of my system, but now the presentation "feels" more musical and involving. The most notable improvements are:
- Better separation of notes.
- Spatial cues in the recording venue.
- Focused vocals.
- Performer position.
- Layering within the soundstage is easier to hear.
Not so much in a way that calls attention to individual notes or sounds in the recording venue, but it makes the presentation much more enjoyable (i.e., it just sounds more like music.)
