TEAC - AP-507 - 140W Stereo Power Amplifier
TEAC AP-507 140W Stereo Power Amplifier
The TEAC AP-507 Stereo Power Amplifier embodies precision Japanese engineering, delivering 140 watts of clean, stable power with exceptional musical transparency. Designed for audiophiles who value pure signal integrity, it operates in fully balanced mode from input to output, ensuring low distortion and wide dynamic range. Housed in a compact yet robust chassis, the AP-507 brings the refined sound signature of TEAC’s Reference 500 series to modern two-channel systems. Its minimalist design, combined with advanced circuitry, makes it ideal for both studio-grade accuracy and high-fidelity listening environments.
At the heart of the AP-507 lies a dual-mono Class D amplifier architecture that provides outstanding control and linearity. It achieves remarkable efficiency while maintaining natural tonal balance and smooth transient response. The amplifier’s balanced XLR and unbalanced RCA inputs accommodate various source components, while the large toroidal transformer ensures consistent current delivery for demanding speaker loads. A robust chassis construction minimizes vibration, and its aluminum panels reinforce electrical and mechanical stability. The AP-507’s output delivers 70 W per channel into 8 ohms, providing ample headroom for both dynamic orchestral passages and subtle acoustic details. Front-panel VU meters, softly illuminated, offer both a visual reference and a touch of vintage elegance that reflects TEAC’s heritage.
For discerning listeners who desire a power amplifier that merges efficiency, control, and musicality, the AP-507 is an inspired choice. Its combination of precision engineering and timeless aesthetic ensures that it pairs seamlessly with preamplifiers and digital sources alike. Whether driving high-sensitivity speakers or powering complex setups, it reveals the nuance, scale, and emotion inherent in every recording. The AP-507 exemplifies TEAC’s commitment to uncompromised sound reproduction—delivering performance that’s as engaging as it is accurate.
