Power Supplies for Naim Audio equipment

These power supplies were designed to replace the Naim FlatCap, HiCap, SuperCap, and XPS power supplies in Naim Audio systems. They provide advantages over the original products at fraction of the cost.

Comparing with the original Naim power supplies, these power supplies will provide a higher level of resolution, better transparency, more detail, better soundstage, deeper and more controlled bass.

These power supplies have a major advantage over the original Naim products, they don't require maintenance or recapping. The performance of the large electrolytic capacitors used by the HiCap or XPS degrade over time and they need to be replaced every 10 years or so. Recapping is an expensive operation that requires sending the power supply for servicing. If you buy a used Naim power supply it will most likely require recapping. Our power supplies are disigned differently and don't rely on the performance of the large elctrolityc capacitors.

The power supply has a major role in sound quality, in many cases more than the circuit design and the component choice. People often ask themselves whether they should replace their preamplifiers or buy a power supply. In this aspect It is woth mentioning that most Naim preamplifiers are based on the same amplification circuitry and differ in their ability to connect more/better power supplies.

The TeddyCap product family is the fruit of several years of design and intensive tests, read more about the technical aspects of it in power supplies under the hood.

We offer several power supplies for Naim equipment, including different combinations of multi HiCap/Napsc functionality in a single case. The TeddyCap replaces a single HiCap, the TeddyCapPlus replaces a HiCap and a Napsc, the DualTeddyCap replaces two HiCaps and a Napsc, the TeddyXPS replaces a Naim XPS, and the TeddySuperCap replaces a Naim SuperCap. The following table summarizes the differences between the models.

Each HiCap repplacement section in the DualTeddyCap is independent, and performs the same as having two intependent TeddyCaps and a Napsc.

* The TeddyCap has a single 4-pin audio sockets which can be used to connect Naim preamplifiers according to the Naim scheme, that is, the audio signal is routed from the pre amplifier to the power amplifier via the power supply. The TeddyCapPlus and DualTeddyCap have two 4-pin audio sockets allowing to connect two power amplifiers (such as the NAP135).

All our power supplies are housed in the same elegant black anodized aluminum case, equipped with a green LED to match Naim systems.

All the power supplies which are currently sold are mk3 version. The design of these power supplies is based on the SuperTeddyReg, a very effective ultra low noise regulator that provides a super clean and stable DC to the equipment. Read more about the SuperTeddyReg.

Please note that that the power supplies are sold without a mains power cord. Thanks to the high filtering capabilities of these power supplies they are less sensitive to the power cord, and excellent performance can be achieved using relatively low cost standard cables. Some people reported improvements using dedicated mains power cable, though the effect my depend on the rest of the system.

All models can be preconfigured to work at 110-120V or 220-240V. Changing the operation voltage is possible but requires soldering.

The TeddyCap History:

2006: TeddyCap mk1 based on a modified version of the ALWSR (pre regulator replaced by Gyrator)

2007: TeddyCap mk2 based on TeddyRegs and improved over time

2009: TeddyCap mk3 based on SuperTeddyReg
