Power amplifiers stereo — TEAC AP-701

The AP-701 is a stereo power amplifier from TEAC, sitting above the AP-505 with considerably greater output power and a substantial input impedance. The AP-701 brings TEAC's more accomplished current engineering to dedicated stereo power amplification.

Key specs that matter

Input sensitivity is 1,600mV, with input impedance at a substantial 64,000 ohms balanced or 32,000 ohms single-ended. Output power is 170W into 8 ohms, rising to 260W into 4 ohms- considerably more than the AP-505's 90W/130W. Frequency response spans a wide 10Hz to 50,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is an exceptional 110dB, with total harmonic distortion plus noise at 0.003% at 100% global feedback. At 444 x 111.3 x 348.2mm and 9.9kg, the AP-701 represents a more substantial commitment than the AP-505.

Sound and use context

Expect exceptionally clean, capable amplification reflecting the exceptional 110dB signal-to-noise figure combined with the considerably greater 260W-into-4-ohms output, representing TEAC's more accomplished current power-amplifier engineering.

Pairing

The substantial 260W into 4 ohms output handles demanding loudspeaker loads with confidence.

Alternatives

TEAC's own AP-505 offers a more accessible alternative within the same broader power amplifier catalogue.
