Evergreen today has released the DN-82623, a Headphone Amp that supports four different inputs including RCA, Digital In, and USB DAC. The DB-82623 comes with a Dual FET-Input, Low Distortion Operational Amplifier TI OPA2604. Right now it's only available in Japan with no word on a western release date. Stay tuned.
