About the E-307
The Accuphase E-307 integrated amplifier was manufactured from 2001 to 2004 in Japan. It features a parallel push-pull output stage delivering 140 watts per channel into 4 ohms and 100 watts per channel into 8 ohms, with very low total harmonic distortion of 0.01%. The amplifier uses current feedback topology for superb phase stability and has separate preamplifier and power amplifier sections to minimize interference. It supports various inputs including balanced XLR and unbalanced RCA, with optional boards for digital input (DAC-10) and analog phono input (AD-10). The unit includes tone controls, a remote control, and a large power transformer for stable power delivery. Dimensions are 47.5 x 17 x 42.4 cm and it weighs 21.6 kg. The original price was approximately 9,900 DM. The E-307 is praised for its detailed, spacious, and natural sound reproduction, making it a reference integrated amplifier of its time.
