Integrated Stereo Amplifier (2005-07)
The E-300 series has always played a central role in the Accuphase integrated amplifier line up.
Drawing from a wealth of know-how and experience, the E-308 incorporates the latest advances in circuit technology and materials research.
It has been designed to deliver one hundred percent of musical enjoyment.
Specially noteworthy is the MCS (Multiple Circuit Summing) topology implemented in the preamplifier and power amplifier sections which drastically improves S/N ratio, allowing utterly natural sound to emerge from a background of deep silence.
An integrated amplifier offers various advantages such as convenient operation and modest space requirements, however, because its overall gain is very high, even the slightest interference or crosstalk at the input can have a considerable effect on the sonic result.
To preclude this possibility, the E-308 is designed to achieve total electrical and structural separation of the preamplifier and power amplifier sections.
These two parts operate as if they were entirely separate components – an EXT PRE switch and dedicated inputs and outputs allow independent use of the preamplifier and power amplifier.
Both the preamplifier and power amplifier use the MCS principle developed by Accuphase, with multiple input circuits connected in parallel.
Together with the current feedback topology, this results in a significant enhancement of all vital performance parameters.
The power amplifier output stage adopts a parallel push-pull configuration of multi-emitter power transistors designed for high-power audio applications.
The large power transformer in the power supply and plenty of filtering capacity sustain ample high-quality output power.
The preamplifier section comprises features such as tone controls, loudness compensator, and facilities for recorder monitoring and copying.
Each circuit component has been carefully selected after extensive tests, the end result being an integrated amplifier that clearly stands out from the rest.
Optional boards can be used to implement digital inputs and high-quality analogue record playback.
