Интегральные усилители — ToneWinner AD-60PRO

The ToneWinner AD-60PRO is a stereo amplifier working in Class AB from ToneWinner, a Guangzhou company that has designed its own products since 1992. It combines a preamplifier, a power stage, a headphone amplifier, a digital input section and a built-in file player in one compact box. It covers stereo music listening and TV sound, and every function is available both on the supplied remote and in the Android and iOS apps.

Key specs that matter

Power reaches 55 W RMS per channel into 8 ohm and 85 W into 4 ohm with one channel driven at 1 kHz and 1 percent THD, and the amplifier accepts loudspeakers from 4 to 8 ohm. Distortion is specified at no more than 0.01 percent THD, noise at 110 dB A-weighted or better and a frequency response of 10 Hz to 200 kHz at +1/-3 dB. Maximum power consumption is below 300 W. The case measures 300 mm wide, 335 mm deep and 83 mm high and weighs 5.1 kg net and 6.3 kg in the carton.

Engineering and use context

ToneWinner fits a large toroidal transformer with high-capacity filter capacitors for the power stage, while the gain circuit is presented as a low-distortion, high-speed design. The digital section accepts one coaxial and one optical input, both up to 24 bit and 192 kHz, plus a USB Type-C input for a computer and HDMI ARC for linking to a TV. Alongside these sit an analog line input and a turntable input that takes MM or MC pickups, which was added as an upgrade over the earlier version. The internal player reads USB drives and TF cards and handles WAV, FLAC and APE lossless files as well as MP3. Bluetooth 5.0 provides wireless streaming from phones and tablets. The front LCD has five brightness levels, and the power supply switches automatically between 115 V at 60 Hz and 230 V at 50 Hz, with CE and FCC certification.

Pairing

The wide impedance rating and the extra power into lower loads leave room for most bookshelf speakers and many compact floorstanders in a room of around 20 m2. The SW-OUT socket feeds an active subwoofer to build a 2.1 system, which suits the HDMI ARC link to a TV. A turntable connects straight to the phono stage without an external preamp, and headphones plug into the built-in headphone amplifier. Because the coaxial, optical, USB and HDMI inputs all feed the internal converter, a CD transport, a computer and a TV may all remain plugged in and be selected from the remote or the app, while the USB and TF card slots cover a music library without a separate streamer.
