The Vinnie Rossi CANTA Stereo Power Amplifier is the latest member of the American brand’s CANTA series, joining the CANTA phono preamplifier, integrated amplifier and preamplifier. It is a dual-mono Class AB design built around MOSFET output devices, rated at 125 W per channel into 8 ohms and 250 W into 4 ohms, and like the rest of the range it is made in the USA.
Inside the Vinnie Rossi CANTA Stereo Power Amplifier
Vinnie Rossi uses a two-board stacked layout and a switch-mode power supply with active power factor correction. The brand quotes THD+N below 0.01% from 20 Hz to 20 kHz, a frequency response of 5 Hz to 100 kHz within ±0.5 dB, a signal-to-noise ratio above 100 dB and an output impedance below 0.05 ohms, which should give a firm grip on demanding loudspeakers.
According to Mono and Stereo, each channel runs two pairs of matched lateral MOSFETs, the amplifier is stable down to 2 ohms, and the power supply is rated at 1,200 W peak inside a shielded chamber. The same report says the output devices are mounted directly on the chassis, which doubles as the heatsink.
A billet aluminium chassis
The chassis is machined from a single billet of AL6061 aluminium, and the amplifier stays low at just 70 mm tall. On the front, a high-resolution LCD and two pushbuttons replace the usual row of switches. The rear carries balanced XLR inputs, 5-way binding posts, a 3.5 mm trigger, a USB-C port for firmware updates and an IEC C14 inlet. The mains input accepts 100 to 264 VAC, so one version covers every market.
The amplifier ships in a hard travel case and is covered by a 10-year warranty, which is unusually long for a power amplifier in this class.
Completing the CANTA system
With the Vinnie Rossi CANTA Stereo Power Amplifier, owners of the CANTA preamplifier now have a matching power stage from the same family, while CANTA integrated owners gain an upgrade path. We covered the series earlier with the Vinnie Rossi CANTA Integrated Amplifier. Full specifications are on the official Vinnie Rossi CANTA Stereo Power Amplifier page.
