Exposure VXN Phono Amplifier: Dual Mono with Dual Power Supply

British Hi-Fi audio brand Exposure Electronics has released the VXN Phono Amplifier. The novelty, according to the company, is addressed to “serious vinyl lovers” and is paired with a branded VXN power supply. If you add another such unit, the system goes into a dual mono configuration. Three or two cases form a neat rack.

The Exposure Electronics VXN Phono Amplifier works with MM or MC cartridges (separate inputs). There are no operational amplifiers in the circuit – only discrete transistors, high-quality resistors and capacitors. Moreover, in the passive correction of the RIAA there are, according to the developers, “polypropylene capacitors of very high quality“.

The result is a signal-to-noise ratio for a frequency of 1kHz and an output voltage of 500mV – >82dB for the MM input, and >72dB for the MC input. Stepped load and gain control is set by jumpers on the rear panel of the all-aluminum black (this is the only color) case.

Availability and price

The Exposure Electronics VXN Phono Amplifier is already on sale in the UK for £1,790.
