The A18 represents an ideal introduction to true Hi-fi amplification. It’s sleek design, flexible connectivity and powerful amplifier stages deliver a level of reproduction far beyond that of “budget” separates systems. Using the latest in amplifier technology plus over thirty years of audio design experience the A18 is an astounding amplifier, true to Arcam’s tradition of affordable excellence.
Using very high quality components and carefully designed multi-layer PCBs the A18 is designed for performance from the ground up. Connectivity is highly flexible allowing direct connection of seven line level sources including a dedicated 3.5mm front panel jack socket for portable music players.
Operation of the A18 is simplicity itself. A rotary encoder allows precise control over volume and other selections such as tone controls and balance. This means delicate audio signals need not travel to and from the front panel or through potentially noisy mechanical potentiometers or switches.

The A18s large power supply uses a toroid transformer which ensures an extremely quiet backdrop to music and superb stability during large bass transients. The chassis features a damped “Sound Dead Steel” construction virtually eliminating mechanical influences on the electronics.
As part of Arcam’s FMJ line of high performance separates, the A18 is an ideal partner for the new CD17 CD player and is available in black or silver finish.
