Headphones can be considered as high quality loudspeakers, but with a much lower power requirement. For this reason, they have distortion levels on an order of magnitude lower than conventional speakers, and therefore are capable of showing up amplifier deficiencies more clearly. What’s more, headphones are one-way systems, with very few exceptions, and for this reason crossovers do not interfere with sound quality. Consequently, a headphone amplifier must offer the best possible sound quality, even at very low volume levels, whilst working not unlike a real power amplifier.
The Canamp, Heed's best-seller headphone amplifier can fulfil all these criteria offering a no-compromise solution in a realistic package. It is the ideal auxiliary amplification for the majority of headphones including many top-class models from all the well-known manufacturers, and even some notoriously low impedance representatives can be driven by the Canamp with astonishingly good results. The synergy of the AKG K701 and the Heed CanAmp is legendary.
The Canamp is a two-stage amplifier. While the first – voltage gain – stage is based on an integrated circuit of the highest audio pedigree, the second – power gain – stage is a single-ended, pure Class-A amplifier. It enables the Canamp to drive virtually any headphones from about 30 ohms up to 600 ohms or more. The signal path is kept to a minimum on its PCB, offering a clean and noise-free sound.
