The idea to house the DIY Headphone Amplifier in a wooden enclosure was taken from the Grado RA1 headphone amplifier which is contained in a beautiful mahogany box.
Mark is very pleased with the performance of this simple and inexpensive headphone amplifier project. For full details, including additional pictures and the schematic, see the DIY CMoy / Grado RA-1 Headphone Amplifier Project page.
