Product Description

Croft Acoustics Micro 25 Line R Pre Amplifier is the line only version of the Micro 25 R pre amplifier. There is a simple circuit that makes up this pre-amplifier yet the music has areas of openess and authority that heavily modified and more complex units struggle to reveal in quite the same manner.

Micro 25 Series

There are three pre-amplifiers in the current range, the new Croft Micro 25 basic, the Croft Micro 25 and the Micro 25 "R", to commemorate the relaunch of Croft Acoustics and 25 years since the original Croft Micro giant killers. The original ethos is back with high performance products at a reasonable price. Cosmetically they are similar to each other as they retain the classic case work. Instead the differences are inside the box.


Micro 25 R Pre-Amplifier employs clever Synchronised Switch Damping over the usual cathode follower valve with the Mosfet not being employed directly in the signal path. R stands for Regulation and gives more grip and control over the whole frequency spectrum. This pre-amplifier is designed to work with Croft Acoustics Power Amplifiers, both pre and powers are phase-inverting.


An extra transformer is employed to manage the regulation circuit. Separate volume controls for left and right channels, Selector switch for phono and three line inputs and a mute switch are on the front panel, along with a power indicator light and on/off switch. The Mosfet regulated power supply makes a big difference to the sound that even valve purists would find hard to fault. The power supply is taken care of with two large toroids and features a regulated HT. There is a MM only phono stage with three line level inputs.
