Audiophile Headphone Amplifier Kit
Audiophile headphone amplifier greatly improves the sound quality, adding three dimensional layered soundstage to any audio source whether it is your desktop computer, laptop, phone, MP3 player, Raspberry Pi, XBOX, SONY Playstation, etc. The kit is built using premium audio grade components such as High Precision Ti OPA2277 opamp for excellent audio soundstage, Ti TLE2426 rail splitter, Ultra-Low ESR 470uF Panasonic FM filtering capacitors, High quality German WIMA input and decoupling capacitors and Vishay Dale resistors. 8-DIP machined IC socket allows to roll & swap OPA2277 with many other dual opamp chips and experience different sound signatures (such as OPA2132, OPA2134, OPA2107, OPA2227, OPA2228, OPA2604, dual OPA132, OPA1612, OPA627, LM4562, TL072, NE5532, and many more). Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.
