E-3000

---

The E-3000 perfectly reproduces the music from its dynamism to the performer's intention, providing satisfaction and pleasure of ownership to all audiophiles.

The E-3000 integrated amplifier emerged from the path forged by the technologies used in high-end equipment.
Among this amplifier’s constituent elements, the vitally important volume control circuits incorporate AAVA that
employs the ANCC principle. The power amplifier section produces balanced signals relying on the instrumentation amplifier principle while simultaneously creating a robust output stage through three-fold parallel push-pull power transistors driven in class AB. Every moment spent immersed in the vibrant playback of the E-3000 is one to relish.

DIMESIONS

The E-3000 is the smallest Class AB integrated amp in Accuphase lineup, compared to previous models. The panel height is 10 mm higher than the full E-280 model and 10 mm lower than the E-380, with balanced proportions. However, it weighs more than the E-380.

Width: 465 mm 

Height: 161 mm 

Depth: 420 mm 

Weight: 23.1 kg

FUNCTIONALITIES

The E-3000 has no sub-panels and all buttons controlling functions are arranged for ease of use. The power meters are larger for better visibility, and on the rear panel, there are two large speaker terminals and two slots for inserting two option boards.

The E-3000 accepts the digital input board DAC-60 and analog input board AD-60.
You can see the figure of the sampling frequency input of DAC-60 on display and can choose any preferred input sources with the selector on the front panel.

The gain values of AD-60 can be set to 66dB for MC and 40dB for MM, and the MC Input impedance can be selected from 4 values, “200 ohms” is newly added.

OUTPUT POWER

The E-3000 can output 100W/8ohms from its compact housing. Its powerful power supply and power amplifier ensure good linearity and a high power output of 150W
even with a 4-ohms load, so it can drive any speakers with plenty of power.

IMPROVEMENT OF AAVA

• 20% lower noise than the E-380（@9 o’clock volume position）
• Utilizing ANCC
• 5 buffer amps paralleled
• Making the V to I Converter low impedance

The AAVA(Accuphase Analog Vari-gain Amplifier) is a radically different volume control principle that eliminates all variable resistors from the signal path.

The E-3000's AAVA module contains five paralleled buffer amplifiers and the lower-impedance V to I converter and utilizes the ANCC, so the E-3000 achieved 20% lower
noise than the E-380.

For the E-3000, Accuphase thoroughly reviewed the AAVA implementations.
Placing the buffer amplifiers close to the input jacks, the E-3000 succeeds in reducing the noise induced between the input jack and AAVA. 

Thanks to this, the E-3000 achieves excellent performance in the induction noise rejection, comparable to the balanced AAVA module adopted for the high-grade
pre-amplifiers.

The E-3000 achieves 600 of guaranteed Damping-Factor, and this is 20% improvement over the E-380 and E-280.

*Damping-Factor, DF:
An index of speaker driving ability. Higher DampingFactor amplifier has higher speaker driving ability.
DF = 8 ohm / Output-impedance
