VMV A1

About the VMV A1

The SMSL VMV A1 is a Class-A amplifier featuring a FET Class-A amplifier circuit that provides 15W x 2 output power into 4Ω, 10W x 2 into 8Ω, and 2W x 2 into 32Ω, making it suitable for both bookshelf speakers and headphones. It uses a simple circuit design that draws constant current, minimizing electromagnetic interference and achieving exceptionally low total harmonic distortion (THD+N) and high signal-to-noise ratio (SNR). The amplifier includes a CNC aluminum shell, an on-screen chassis temperature display, a stabilized power supply, and a GPA2311 volume control chip for precise volume adjustments. Connectivity includes RCA inputs, speaker terminals compatible with banana plugs, and a 6.35mm headphone jack. Technical performance includes THD+N of 0.01% at 4Ω, 0.008% at 8Ω, and 0.002% at 32Ω, SNR of 110 dB, and channel separation of 105 dB. The unit measures 210 x 205 x 39 mm and weighs 2 kg. It comes with a remote control, power cord, and user manual. The VMV A1 has been discontinued as of 2022 but remains noted for its massive analog power and minimalistic feature set, praised for its sound quality and build.
