About the E-211
The Accuphase E-211 is a high-end integrated stereo amplifier produced by Accuphase Laboratory in Japan between 1998 and 2001. It features a parallel push-pull output stage for quality power delivery, current feedback circuit topology to prevent phase shifts, logic-controlled relays for optimal signal routing, high-quality tone controls, balanced XLR inputs, support for two pairs of speaker outputs, and a supplied infrared remote commander RC-23. Optional boards like AD-9 or AD-50 enable phono (MM/MC) input. Designed for 100V AC (Japanese market), it offers exceptional audio performance with low distortion and high damping factor. Color: Champagne. Original price approximately 4,900 DM (equivalent to about 1,190 EUR for optional phono module). User reviews praise its sound quality and versatility.
