Description :
The Accuphase E-306 is designed to achieve total electrical and structural separation of the preamplifier and power amplifier sections. It opens up a new chapter in music reproduction, offering sound quality that rivals some of the best separate components. An important feature of the E-306 is the use of current feedback circuit topology in the power amplifier which eliminates phase shifts in the upper frequency range and assures uniform frequency response which does not change with gain. That results in a combination of total operation stability with excellent frequency response. Thanks to this principle, this assures excellent transient response, with superb sonic transparancy and detail. Music reproduced by the Accuphse E-306 sounds uncannily real. The preamplifier section incorporates a high-quality discrete-type line amplifier and a phono equalizer for reproduction of analog discs, using MM or MC cartridges. The E-306 incorporates a high-performance phono stage designed to enable top-notch reproduction of your valuable analog records. Separate input circuits are provided for moving-coil (MC) and moving-magnet (MM) cartridges, to fully bring out the advantages of each cartridge type. All parts and circuit components of the E-306 have been strictly selected for sonic purity. The power transistors are designed for audio applications and have been selected for optimum frequency response, forward current transfer, ratio linearity, and switching performance characteristics. The E-306 spares no efforts in this regard, featuring a large 500VA power transformer and two large electrolytic capacitors rated for 22,000mF each. This assures ample reserves also for reproduction of demanding bass passages. The large analog power meters have a peak hold function, which lets the user easily monitor the output level of the rapidly fluctuating music signal. Thanks to logarithmic compression, the meters cover a wide dynamic range. The simple, uncluttered design in the tradition makes the Accuphase E-306 a joy not only for the ears but for the eyes as well.
