Accuphase E-6000 integrated amplifier at the brand's peak with 260 W

Accuphase's new Class-AB integrated amplifier E-6000 has become the brand's most powerful model in this category. According to the German Modernhifi report, the device ranks above the E-5000 which delivers 240 W. There are two card slots for digital sources and turntable.

Which features stand out?

• Power: 260 W at 8 ohms, 350 W at 4 ohms
• Analog inputs: 5 RCA, 2 XLR, plus recorder connection and Main In
• Dimensions and weight: 46.5 x 22.1 x 50.2 cm; 38.6 kg
• Signal-to-noise ratio: 112 dB (manufacturer specification)
• Damping factor: 1,000

PRE OUT and MAIN IN outputs are offered in both RCA and XLR. Thus the E-6000 can be used as preamp only or power amp only. For bi-amping, a second power amplifier can drive the bass section while the E-6000 drives the treble section; for this the speakers must have separate terminals for both sections.

How are optional cards and circuit design structured?

Without a card installed, the device processes analog signals only. The DAC-60 card adds USB, coaxial and optical inputs; via USB it accepts PCM up to 384 kHz and DSD up to 11.2 MHz. The AD-60 card provides phono stages for MM and MC cartridges; MC input impedance is selectable between 30, 100, 200 and 300 ohms, and the circuit includes a switchable subsonic filter. The LINE-10 brings an additional RCA input. The older DAC-50 and AD-50 cards are also compatible.

At the output stage, six parallel transistor pairs per channel operate; in the E-5000 this number was five. The circuit design is derived from the brand's most powerful Class-AB stereo power amplifier P-7500. Sound level is adjusted not by potentiometer but by Accuphase's AAVA method. In the power supply, the toroidal transformer diameter has grown by 25 mm, and two filter capacitors have increased from 40,000 µF to 47,000 µF.

Why does it matter?

For Hi-Fi enthusiasts seeking a high-powered, card-expandable integrated amplifier, the power, input options and bi-amping possibilities are clearly laid out. The source contains no information on Turkey pricing or availability.
