DIY with valves and semiconductors
Most commercial preamplifiers and power amplifiers have a headphones output. However, because of its simplicity the sonic quality of such an output is often judged as ‘mediocre’. Optimum sound reproduction in a pair of expensive headphones requires a dedicated amplifier and these, unfortunately, are rarely seen in the highstreet hi-fi outlets. The Internet however offers many alternatives provided you are prepared to go for home construction.Many professional electronic engineers once started their ‘career’ with the construction of a headphone amplifier. This is not surprising, the circuits being relatively simple and requiring little theoretical knowledge of electronics.
