Heed Audio CanAmp, headphone amplifier
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 fibreglass PCB.
