Description

The Eleven Audio Formula S is a technological tour de force. It is a dual mono solid state amplifier which delivers stunning speed and clarity, with hard hitting bass and drums and beautifully smooth tube-like decay to cymbals and string instruments.

The Formula S was specifically designed for the ABYSS AB-1266 Phi CC so that this headphone’s resolution and musical abilities could be realizsed. However that does not mean that it should only be used with Abyss AB-1266 headphones. The fact that it was designed to drive such a demanding and resolving headphone means that this amplifier will work its magic on ANY full-size high-performance headphone.

It’s compact size also means that it takes up less real estate on your desktop and it can be upgraded by simply adding the Eleven Audio Powerman external power supply.

How do you describe its sound?

Impeccable balance, smooth and clear to the source, excellent bass definition, highly refined, detailed yet full sound with plenty of harmonic richness approaching that of a high-performance tube amp. It is a true connoisseur’s destination headphone amplifier. Excellence personified.
