FS:SICPHONES amp. Assembled headphone amp purchased from the Kickstarter campaign. Single-ended amp that will drive just about any headphone. Has the MOSFET output transistor, not the SemiSouth JFET. Although the amp will drive phones from 32-ohm to 600-ohm, it was designed to drive phones from 250-ohms to 600-ohms optimally. With low impedance phones the sound quality is the same as with high impedance phones, but you will hear some background hiss due to the higher gain the amp has. With higher impedance phones such as the Sennheiser 600, 650, and 800 or 600-ohm Beyers or AKG's this amp will be very quiet and really control the phones sound. Originally came with a small 24-volt switching power supply which I replaced with a massive Lambda linear highly regulated power supply which takes the amp to an even higher level of sound quality.
