 The Teddy24 power supply can be used to replace the small AC plug-in power adaptor that comes with many audio equipment, routers, NAS etc, and provides significant improvement in sound quality.

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 Teddy24 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 Teddy24 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 Teddy24 power supply noise level is very close to the zero Volt reference.

Interconnects

The Teddy24 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.

    Twenty days ago I received the order package, the package arrived one day before the scheduled delivery date. Everything arrived in correct condition and the DHL parcel service did its job well.

    The Teddy24 PSU has a rugged look, has a very good finish, and looks good in the Rack with the whole system. Its finish is simple, a green led light on the front panel and the connectors on the rear panel. The connector for the DC cable is of very good quality as is the cable that is supplied with the power supply with a 2.5mm connector. These finishes are the result of the good work they are doing at TeddyPardo. Add that Teddy24 is provided with a fuse, a rare option in other power supplies, which allows upgrades with higher quality fuses. The upgrade of a fuse is a highly recommended option, for little money you can obtain frankly positive results in the system, little great detail.

    Before listening I left the power supply running for 15 days. This font needs time to run to show its potential.

    Teddy24 has been purchased to replace the PSU1 power supply of a Graham Slee Reflex M phono preamplifier. The PSU1 and Reflex M set works well, it has good dynamics. Depth, focus, and timing are good too. The grain is adequate and the sound expansive. It is a remarkable set.

    Swapping the PSU1 for this Teddy24 provides a 10% increase in overall sound quality. This improvement occurs in all frequency ranges, although at low frequencies this improvement is greater than that experienced at higher frequencies. The bass sounds are deeper and more intense, the middle sounds of the voices and percussion instruments are also noticeably better, more face-to-face and the high frequencies are slightly finer, all with remarkable cleanliness and transparency.

    For this audition I have used an Audio-Technica cartridge (150€), with another higher-end capsule, even better results can be obtained.

    To achieve its full potential, Teddy24 has to stay on as long as possible, it does not give off heat, so it is possible to leave it permanently on.

    It is possible that there are those who feel somewhat penalised in the aspect of the dynamics, Teddy24 acts with a lot of cleanliness and transparency, creating deeper blacks, this quota of clean sound penalised the reproduction dynamics very slightly.

    In conclusion, Teddy24 is a power supply that does its job very well and gives to Reflex M by Graham Audio more depth in the bass, more face-to-face midrange sounds and more finesse in the grain of the high frequencies, with a noticeable increase in the sound cleaning. Teddy24 has given my system a highly recommended update.
