Musical Fidelity A1*

The Musical Fidelity A1 has become one of the most classic designs – inside and out. First released back in 1985, it quickly made waves for being an absolute beast when it came down to driving some of the most difficult speakers of that time, even though it was actually a rather low powered integrated amplifier.

But: it was all done in pure Class A with excellent and expertly laid out discrete symmetrical circuitry topology and using only highest quality components. The A1 showed people that there was more to amplifiers than just high power.

Above all, the A1 is built around a completely discrete and symmetrical Class A topology.

It‘s able to output 25W of pure Class A power @ 8 ohms load with 25A of maximum output. While the numbers here might seem rather low, the ability for the output stage to drive difficult speakers is a small miracle in itself. In addition, the amp design being dynamic class A, and if Class A standing current is exceeded, it will automatically allow more.

It therefore “slides” (NOT “switches”) smoothly into class B style operation, temporarily allowing the further current draw needed.

Details:

Musical Fidelity A1 has one secret. This secret is simple: it makes music. It sounds sweet and fluid and creates a beautiful atmosphere around natural instruments. Especially in small to mid-sized rooms, carefully set up with a pair of great two-way speakers. It is not a powerhouse, but music lovers will cherish its abilities.

The A1 has a sweet, warm, full and exciting sound. No harshness. No grain. Just pure music. It doesn‘t get muddy, and despite its lower power, drives difficult speakers with ease. It remains clean right up to its power limit. To hear what the A1 does is to hear what Hi-Fi is supposed to do: it makes music, pure and simple.
