Japanese high-end audio manufacturer Technical Audio Devices Laboratories (TAD) has introduced its first integrated amplifier.
The new TAD A1000 expands the company’s Evolution Series with its first ever integrated amplifier. Until now, the brand has been primarily known for separate preamplifiers, power amplifiers, and loudspeaker systems in the reference segment. With the TAD A1000, the company is bringing together key technologies from its electronics architecture into a single component. According to the manufacturer, the integrated amplifier is intended to deliver the brand’s characteristic sound in a more compact format without compromising its quality standards.
“With the A1000, TAD opens a new chapter in its product history,” says Jürgen Timm, Business Consultant at Technical Audio Devices Laboratories. “The amplifier is aimed at music lovers who appreciate the brand’s sonic DNA but prefer a more compact solution than a separate preamp/power amp combination. At the same time, our standards remain unchanged: the A1000 is not meant to be simply an entry point, but a fully fledged representative of the TAD philosophy. In other words, it’s an integrated amplifier designed to demonstrate just how much high-end performance can be packed into a single component.”
Symmetrical design and Class D amplification
A central element of the design is a fully symmetrical signal path. The A1000 uses a bridge-tied-load topology in which two independent amplifiers per channel operate in push-pull configuration. Positive and negative signal components are processed in a mirrored manner, which according to TAD allows for more precise control of the loudspeaker drivers.
The mechanical layout follows the same symmetrical concept. The power supply, circuits, and signal paths are arranged in mirrored positions. Circuit traces and cable lengths are designed to be identical in order to minimize sonic influences caused by asymmetries, according to the manufacturer.
The amplifier stage uses Class D technology. The A1000 delivers a rated output of 250 watts per channel into four ohms and is designed to drive demanding loudspeakers, according to the company.
Emphasis on preamplifier and power supply
The preamplifier section is based on a single-stage current-feedback circuit. According to the manufacturer, the FET transistors used in the design are individually measured and then selected as complementary pairs. Volume control is handled by an electronically switched resistor ladder that is intended to ensure precise level adjustment.
Particular attention has also been paid to the power supply. It is built around a toroidal transformer with a linearly regulated supply. Additional design measures include large smoothing capacitors with a capacitance of 33,000 µF as well as non-magnetic resistors and capacitors.
The amplifier chassis is divided into four separate chambers for the preamplifier, power amplifier, power supply, and control circuitry. Specially developed feet with integrated spikes are designed to reduce vibrations from the supporting surface.
As matching components, the manufacturer recommends products such as the SACD/CD player TAD-D1000TX and loudspeakers including the E1AX, CE1TX, and ME1TX. The new integrated amplifier will also be demonstrated from June 4 to 7, 2026 at the High End in Vienna.
TAD A1000 availability and price
The TAD A1000 is available now through authorized specialty retailers. The manufacturer’s suggested retail price is €26,000 including VAT.
