Heed Audio Canamp. Headphones amplifier.

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, our bestseller headphone amplifier can fulfill all these criteria offering a no-compromise solution at a realistic price – in fact, given its technology and manufacturing quality we might even say at a „discount" price. It is the ideal auxiliary amplification for the majority of headphones including many top-class models from Sennheiser, AKG, Beyerdynamic, Audio Technica, Goldring and Ultrasone, and even some notoriously low impedance Grado's and Denon's 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 32 ohms up to 600 ohms. The unit has no internal wiring, and the signal path is kept to a minimum on its PCB. Its high-quality, 1 dB-tolerance Blue Alps volume pot goes through a further selection process during manufacturing to achieve an even tighter, 0.5 dB tolerance.

The CanAmp not only has a line-level input but offers a line-level output to boot; it can therefore be connected to the TAPE MONITOR output of an amplifier, leaving the TAPE output free for additional components (MP3, MiniDisc, CDR, etc.). Gold-plated RCA terminals are used, and soldered directly onto the fiberglass PCB.
