Description
The TeddySB3 power supply replaces the small wall-wart power supply that comes with the Logitech Squeezebox 3, and provides significant improvement in sound.
The design is based on the experience gained with the TeddyCap family of power supplies for Naim Audio equipment, and uses the same technology.
Performance
The small power supply which is provided with the SB3 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 aftermarket 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 TeddySB3 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 TeddySB3
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 TeddySB3 power supply noise level is very close to the zero
Volt reference.
Sound
Plug
in the TeddySB3 and you immediately hear a dramatic reduction in the
noise floor, far better bass quality, improved dynamics, sound-stage
openness. There is a notable reduction in hardness, edginess in the mid
to upper frequency range, tonality is more natural. All this without
any loss of musicality, in fact the with the TeddyCap there is a
greater sense of musicality!
Interconnects
The TeddySB3 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.
