Accuphase E-308 Integrated Amplifier

The E-308 separates the preamplifier and power amp sections in terms of both mechanism and circuitry, preventing interference between them and refining performance and sound quality. It is equipped with an "EXT PRE function" and dedicated input and output terminals, allowing each section to be used as an independent amplifier.

Both the preamplifier and power amp sections are equipped with MCS circuits to significantly improve the signal-to-noise ratio, and the parallel push-pull wideband output transistors and large power transformer deliver brilliant power born from deep silence.

The preamplifier section is fully equipped with a variety of functions, including tone control and other sound quality adjustments and a recorder function, and an optional board is also available for enjoying high-grade CD playback and analog records via digital input.

・ Equipped with MCS circuit for both preamplifier and power amplifier

・ High quality power of 100W/8Ω×2 by parallel push-pull output stage

・ Current feedback amplifier circuit boasts excellent sound quality and stability

・ Shortest signal path by logic relay control circuit

・ Equipped with tone control circuit

・ Powerful power supply section by large transformer

・ Playback of analog records and digital inputs is possible by adding optional boards
