TEAC AP-505
The AP-505 is a versatile stereo power amplifier based around a high-performance, TEAC-tuned, Hypex Ncore power amplifier module, housed within a compact and elegant case.
Capable of operating in bi-amp and BTL (Bridge Tied Load/Bridged) modes, in addition to conventional stereo operation, the AP-505 produces a maximum 130W + 130W of output power in stereo/bi-amp modes and 250W in BTL/bridged mode. At its heart is an Ncore power amplifier module, made by Hypex of the Netherlands and specially tuned by TEAC’s R&D team, for superlative sound quality
As for the exterior, lightweight aluminum-alloy panels cover a robust steel chassis. A pair of large level meters add visual interest when the amplifier is in action, while TEAC's patent-pending ‘Pin-point’ feet, located at three strategic positions on the underside, add incision to the sound, helping to create a more detailed and stable stereo image.
Full-metal, small footprint body for rigidity, stability and elegance
Every external panel – at the front, top and sides - is formed from high-grade aluminium alloy, firmly attached to the robust steel inner chassis. This method of construction helps reduce the transmission of mechanical vibration, ensuring that every single element inside the unit is allowed to perform at its best. Thanks to its convenient A4-sized footprint, the AP-505 easily slots into modern interiors where space-efficiency is important, such as on a desktop. This is in stark contrast to most conventional bi-amp/BTL-capable power amplifiers which are usually bulky, full-width units.
Fully-balanced design
By employing a fully-balanced circuit design from the input section to the output stage, the AP-505 keeps the audio signal as unadulterated as possible as it moves through the amplifier, the result being extremely low distortion levels and an excellent signal-to-noise ratio (assisted by the effective elimination of common-mode noise).
