Brit hi-fi firm Musical Fidelity has announced the “most advanced pure Class A amplifier ever made” in the shape of the mammoth AMS100.

The hugely powerful, and simply huge (pictured with Sandy from the Musical Fidelity office) power amp can deliver 2 x 100 watts of pure Class A power and takes its design inspiration from the lower-powered AMS50 and MF’s massive Titan power amp. More precisely, the company claims it has “the same basic circuit as the AMS50 but even more of it, and precisely the same circuitry and number of output transistors as our monster Titan”.

Like its little brother, the AMS50, the AMS100 is a bridged design, with separate power supplies for each half of the bridge, each supply using the company’s unique choke regulator to give a power supply noise rejection ratio of 88:1. It also uses a large number of capacitors for dynamic consistency under all load conditions.

The company promises it can deliver ultra low distortion from 20Hz to 20kHz with ultra-low distortion consistent up to 50kHz at “normal listening levels”. It can also double its power into 4ohms, and is within 0.25dB of doubling again into 2ohms.

It’s not for everybody, and Musical Fidelity admits that the AMS100 is very much a niche product. A spokesman said: “It’s expensive, it’s huge, it’s heavy, and it sounds like heaven. The AMS100 has been designed for an elite band of audiophile purists who want the ultimate Class A amplifier ever made. We don’t expect to sell many. Those lucky few who get their hands on one will be fulfilled.”

The Musical Fidelity AMS100 will go on sale later in July for £12,999.
