TEAC AP505B Reference 500 Series Stereo Power Amplifier – Black

A stereo power amplifier that is incredibly small and uses Hypex Ncore technology to enable bi-amping or BTL (Bridge Tied Load/Bridged) mode A high-performance, TEAC-tuned Hypex Ncore power amplifier module contained inside a small, stylish housing, serves as the foundation of the adaptable stereo power amplifier known as the AP505B.

The AP505B may operate in stereo, bi-amp, and BTL (Bridge Tied Load/Bridged) modes, in addition to traditional stereo operation. In stereo and bi-amp modes, the AP-505 can output a maximum of 130W + 130W and 250W, respectively. Its core is a Ncore power amplifier module developed by Dutch company Hypex that has been expertly tweaked for outstanding sound quality by TEAC’s R&D team.

A sturdy steel chassis is covered by lightweight aluminum-alloy panels on the outside. When the amplifier is in use, two huge level metres offer visual interest, and three strategically placed “Pin-point” feet on the underside of the amplifier lend incision to the sound, assisting in the creation of a more stable and detailed stereo image.

NCore Audio Power Conversion

The Hypex Ncore power amplifier module used in the AP505B is high-performance and energy-efficient, producing 250W in BTL mode or 130W + 130W in stereo/bi-amp modes. The module, which has been meticulously calibrated and tweaked by our engineers after undergoing rigorous listening tests, readily drives a variety of speakers, giving anything from a pianissimo to a fortissimo and everything in between. Therefore, it accurately mimics the dynamics of real music.

Stereo, Bi-amp, And BTL Modes Are Supported

By placing a few AP505B units side by side, this little unit offers multiple speaker driving modes, Bi-amp, and BTL modes in addition to the traditional stereo mode with 130W + 130W of output power. While the BTL modes create 250W of output power in each channel, the Bi-amp mode drives the woofer and tweeter separately.

Stiffness, Stability And Elegance Provided By A Full-Metal, Small-Footprint Body

Every exterior panel, including those on the front, top, and sides is made of a sturdy steel core chassis and a high-grade aluminium alloy. This technique of construction ensures that every component inside the unit is able to operate at its peak performance by reducing the transmission of mechanical vibration. Because of its practical A4-sized footprint, the AP505B fits in seamlessly in contemporary settings where saving space is crucial, like a desktop. Contrast this with the majority of traditional bi-amp/BTL-capable power amplifiers, which are typically hefty, full-width equipment.

Full-Scale Balance

The AP505B maintains the audio signal as pure as possible as it passes through the amplifier by using a fully balanced circuit design from the input section to the output stage. This leads to extremely low distortion levels and a fantastic signal-to-noise ratio (assisted by the effective elimination of common-mode noise).

Components That Have Been Carefully Chosen And Are Only Used In Hi-Fi Applications

High-quality MUSES8820E dual op-amps are used at the input stage, where sound quality is essentially determined, for both the XLR and RCA inputs. The left and right channel rectifying circuits use four high-capacity 4700F capacitors on each channel (8 in total) in the power supply part of the input stage to achieve distinct soundstage separation between the left and right channels.
A well-designed circuit provides great signal integrity at the XLR input portion, in part due to the removal of coupling capacitors, which frequently cause audio information to be lost as a signal passes through them.

Large Toroidal Power Transformer

The AP505B’s power supply uses a large capacity toroidal-core transformer while the rectifying circuit uses Schottky barrier diodes. Schottky barrier diodes, as opposed to conventional diodes, lessen rectifier noise, resulting in a “cleaner” supply and a more steady delivery of current.

Easy Installation Thanks To ‘Pin-Point’ Feet

The AP505B uses the “Pin-Point” feet that TEAC is attempting to patent. These consist of two independent metal pieces enclosed in a single housing. One is attached to the chassis’s bottom and has a spiked top, while the other has a basin-shaped base with a flange-shaped cup that hangs down from the spiked area. The ‘Pin-Point’ feet have a special design that significantly reduces vibrations and resonance because the unit is held by just three points and has a very limited surface contact area. This arrangement improves the soundstage and enhances fine auditory clarity by reducing mid- and low-frequency muddiness.

Design Using Passive Cooling For Silent Operation

Designing an amplifier that produces a pair of speakers with outstanding sound but also produces a cooling fan that is always making noise is absurd. Our engineers were adamant from the beginning to adopt a circuit and layout that would permit adequate natural cooling, enabling the design of a small but powerful amplifier that didn’t require a cooling fan.

Dual Analogue Level Meters Indicate The Musical Tempo

The AP505B front panel’s analogue level metres move in reaction to signal levels, providing an aesthetically pleasing indication that the amplifier is functioning as intended. Users may alter the display’s intensity in four steps (bright, mid, dim off), and a switchable sensitivity (0dB, +20dB, movement off) lets them choose whether they’d like to see more, less, or even no metre movement.
Naturally, you can determine the device is on even if the lighting is out and the metre movement has been disabled by looking at the location of the power switch!

Magnat SB503M Signature 503 3 Way 6.5″ Bookshelf Speaker – Mocha – Pair

The Magnat Signature 500 is the entry level to the world of audiophile hi-fi. Here, elaborate chassis with the latest technologies are combined with production quality that is second to none in this class. And all of this with a system – because, from the audiophile stereo set-up to the ambitious, perfectly sounding home cinema with active subwoofer, everything can be combined entirely to your liking in the Signature entry-level class.

Elaborate Chassis Technology

The heart of the fabulous high-frequency reproduction is our new hi-res module with two, yes two fmax tweeters. A 1.2″ dome with a particularly wide bead allows it to operate with a low crossover frequency and therefore connect perfectly to the mid-range unit. The additional ¾” super dome tweeter is the basis for extended frequency response to beyond 50 kHz. It also displays excellent all-round dispersion characteristics. In this combination, the module is certified with the Hi-Res Seal by the Japan Audio Society.

The FE Dynamics woofers and subwoofers have specially coated diaphragms that are checked for interference resonance and optimized using laser technology, the so-called Klippel method. A ventilated voice coil unit, the speaker drive, guarantees optimum cooling and, therefore, maximum resilience – even when things really get going.

Exceptional Production Quality

The solid MDF housing is low resonance, providing the best sound conditions for the chassis. The baffle of the Signature 500 is coated with high-gloss black piano lacquer in the black ash models, with the mocha finish complemented by a silk-matt anthracite front panel. Sturdy decorative rings held by six screws not only perfect the look, but also the seating of the speakers. The removable fabric cover allows the choice between a very subtle look and one revealing the technology. The crossover, made of high-quality components, operates with 24 dB cut filters, is amplitude and phase-corrected and therefore enables precise control of the individual chassis. Amply dimensioned terminals not only allow use of the highest-quality cables, they also facilitate bi-wiring and bi-amping, i.e. the use of different cables or amplifiers for bass and treble ranges. How much attention to detail has been invested in the design of the Signature 500 is also demonstrated by the use of the Airflex port with a rounded reflex opening, which minimizes flow noise.

Can be Combined in a variety of ways

The Signature 500 is available in various versions. This means that fans of pure stereo playback can combine different setups, while home cinema enthusiasts can also choose the perfect combination. A shelf-top speaker, the Signature 503, two different size floor-standing loudspeakers, Signature 505 and 507, and the Signature Center 53 speaker make it possible to find the perfect solution for every room and every acoustic requirement.

Highlights:

• Hi-Res certified dual tweeter module with two fmax domes
• Three-way speaker with bass reflex technology
• Klippel-optimized bass-midrange unit
• Ventilated voice-coil unit for maximum resilience and dynamics
