• Cambridge Audio’s phono preamps
Cambridge Audio is celebrating the vinyl revival with a pair of phono preamps aimed to bridge the gap for those whose amplifier has no dedicated phono input — or for those desiring an upgrade from the mediocre circuits often used, especially through years of vinyl decline.
There are two models — the relatively bare-bones Solo phono preamplifier for moving magnet cartridges, and the Duo which, as its name suggests, also supports moving coil models. The Duo (above right, with the back panel below) also adds a high-quality headphone amplifier, so you could have it on the desktop with just your turntable, enjoying vinyl in personal comfort.
Both models use a switch-mode power supply and circuitry which is almost entirely surface mount, assisting extremely short signal paths. The left/right channel balance is adjustable via a small potentiometer fitted to the rear panel, and the included subsonic filter aims to eliminate those embarrasing low frequency rumbles that can be caused by your turntable (Cambridge Audio ascribes rumble to “imperfections within your vinyl” but we’d beg to differ.
In keeping with Cambridge Audio’s ‘green’ philosophy, the units automatically switch into standby if unused for 20 minutes, in which mode energy consumption drops to less than 0.5W.
Pricing here is $299 for the Solo and $449 for the Duo; we hope to have a review for you next issue.
