The TeddyAmp
is a family of high end amplifiers designed to provide a pure and realistic
sound, which contributes to many enjoyable and exciting listening hours without
fatigue.
The TeddyAmp
power amplifiers have output power ranging from 60 to 100W in stereo,
mono-block, and bi-amp mono-block configurations. All amplifiers are based on
the same design concepts and housed in a relatively compact enclosure.
Each of the
power amplifier channels is powered by four ultra low noise regulators (eight
regulators in the case of mono-blocks) which provide stable current to the
power amplifiers.
To
illustrate the importance of a power supply in a power amplifier imagine that
you need to precisely move a heavy weight back and forth. In order to do so you
will need something stable to hold as a reference. Now imagine that your
reference moves while you pull or release it, your task will become very
difficult and the movement of the weight cannot be precise.
The power
supply is the amplifier's reference. While no power supply is perfect, actually
they are almost always quite far from that.
The
transformer which is the heart of the power supply is made of copper wire which
has its own impedance. Due to that impedance, when current is drawn from the
transformer its output voltage drops, usually by 3-10% depending on the
transformer quality and the current being drawn. To minimize this effect most
manufacturers use large oversized transformers that have lower impedance, and
huge smoothing capacitors that serve as power reserve. Even with oversized
transformers and a large bank of huge capacitors the ripple on the power rail
remains in the order of several volts! Furthermore, this power is rarely
filtered and contains noise at all audible frequencies, having a detrimental
effect on sound quality.
To overcome
this problem, some high end manufacturers use linear regulators in their power
supplies. Linear regulators which are based on a feedback mechanism indeed
reduce the ripple, but still suffer from a relatively high level of noise and
other deficiencies inherent to way they operate.
The TeddyAmp
is based on a different approach. It uses a proprietary ultra low noise zero
feedback regulator, a high power version of the SueprTeddyReg, which provides
clean and stable power supply to the amplifier. This results in a natural sound
with quite background which reveals every micro detail of the music, while
maintaining a powerful and controlled bass.
In addition
to the sound advantages, using this power supply it is possible to build
reasonably sized amplifiers with a sound quality which surpasses much larger
and heavier amplifiers. A 60W TeddyAmp sounds much bigger and controlled than
many 100-200W amplifiers costing several times its price, and indeed, the
amount of controlled bass that the TeddyAmp provides is often among the first
things that strikes the listener.
A discrete
component input buffer stage, based on a zero feedback JFET proprietary design
at the input of the TeddyAmp improves impedance matching and provides a silky
sound, typical to high quality valve amplifiers. The input buffer stage is
powered by a pair of ultra-low noise SuperTeddyRegs.
The TeddyAmp
is built using the best available components: selected low noise JFET
transistors, low noise Tantalum and PPS capacitors, and WBT NextGen sockets and
binding posts. All components are mounted on a four layer immersion gold FR4
PCB with a star ground topology.
TeddyAmp ST60
The TeddyAmp
ST60 is a high-end 60W stereo power amplifier which can be used as either a
stereo amplifier or in bi-amp configurations. Its drive capabilities are much
higher than its size or its 60W power suggests.
Like with
all TeddyAmp power amplifiers, the soundstage is large and 3-dimentional,
instruments breathe, and there is a sense of air and space between them.
The ST60
provides a realistic and natural sound, capable of driving with full control
and accuracy, the most demanding speakers.
A single
ST60 can be used as a stereo amplifier, or a pair or ST60 can be used in bi-amp
configurations where each ST60 drives a bi-wireable speaker.
TeddyAmp MB100
The TeddyAmp
MB100 is a high-end 100W mono power amplifier which is designed to be used in
pairs to create a stereo system. Thanks to its relatively small size several
units can be used in a muti-chanel system.
The MB100
drive capabilities are much higher than its size or its 100W power suggests.

all TeddyAmp power amplifiers, the soundstage is large and 3-dimentional,
