Description
Compact stereo power amplifier with audiophile
standards
The Stamp is aimed at music lovers looking for a
serious power amplifier without a large device format. The concept:
puristic, rich sound with understated aesthetics – suitable for a main system,
secondary system, or setups with compact loudspeakers.
Neutral
tuning – clear, precise, controlled
In press reviews,
the Stamp is primarily praised for its neutrality, objectivity, and clearly defined clarity.
This means the amplifier aims for a reproduction that sounds precise and
uncolored – as is appreciated in studio-oriented tunings.
High-quality construction and well-thought-out
power supply
Inside, first-class components are used
(including components from Nippon Chemicon, BC Components, and Epcos). For a
low-loss power delivery, the double-sided PCB is designed with 105 μm
copper plating.
The internal audio cabling is entirely
solid-core and directly soldered to sockets and the PCB to avoid
additional plug connections. The oversized linear
power supply is fed by a magnetically and statically shielded toroidal transformer.
Power and suitable
loudspeakers
Despite its very compact dimensions, the Stamp delivers up to
2 × 20 W into 4 ohms. Loudspeakers with an
efficiency of 87 dB/1 W or more are mentioned as particularly suitable partners.
Flexible integration:
space-saving mounting and optional bi-amping
Thanks to its small form factor,
the Stamp can be easily placed next to the system. With an optional
mounting kit, discreet mounting is also possible, for example, under desk surfaces
or on walls.
For bi-amping, the Stamp can be reconfigured – for this,
two Stamp power amplifiers are required.
