Eleven Audio 'Formula S' High Purity Headphone Amplifier

Dual mono amplifier modules within the black anodized aluminum chassis of this Eleven Audio headphone amp 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 amp is tuned for the highest resolution music and headphones. Impeccable balance, smooth and clear to the source, excellent bass definition, simply put the dedicated headphone amp every conneseur seeks. And it's stout size takes up less real estate on your desktop.

Note from Joe@ABYSS:The Formula S amplifier was specifically designed for the AB1266 and comes as a highly recommended mate to appreciate the headphones resolution and musical abilities. Given it's power and gain the Formula S will work it's magic on any full size high-performance headphone.

The sonic signature of this amp can be best described as having a highly refined, detailed yet full sound with plenty of harmonic richness approaching that of a high performance tube amp without the heat. As amplifiers go, in my 30+ years in audio it's sonic signature is what everyone seeks as they spend too many years on the merry-go-round.
