Description
Accuphase E-700 is freshly on our shelves as a replacement for the stellar and much loved E-650. We are pleased to report that the E-700 is a significant step up over the outgoing model but less happy to report that, as ever, supplies are likely to remain very limited!

“A forty year Naim man; I was ‘turned’ in the summer of 2021 onto Accuphase electronics and decided after auditioning that a good integrated amp was all I needed. Enter the E-480 which served me very well for three years.
I’ve recently upgraded to the Class A E-700. It builds on the strengths of the 480, opening the musical window wider. There is increased resolution, clarity, transparency and spatial awareness. Instruments and vocals seem to exist in a larger 3D space with more freedom. Sustain/decay is more obvious and the timbre of instruments is more apparent.
Don’t confuse Class A with the sound of some valve amplifiers. The dynamic slam is phenomenal with superb rhythmic drive and control. Warm; fluffy and cuddly, this amplifier most definitely is not.
I recall the Skottish Gramophone Kompany many years ago re-using Jaguar’s sales slogan ‘Grace, Pace and Space’. That nails it in three words.
I’m loving my new amplifier and one has to hand it to Accuphase for value for money too. With several performance tweaks and an increase in power output, the 700 costs only £200 more than its excellent predecessor; the E-650.”
How Accuphase see it:
The E-700 is an evolutionary integrated amplifier that incorporates numerous technologies from our 50th anniversary flagship model, the E-800. The preamplifier section uses a Balanced AAVA type volume control with ANCC to create a balanced configuration from input to output and achieve driving perfection. The power amp stage that drives the speakers has been fortified from three elements to four, further increasing reliability. Experience the full breadth of emotion in live performances with the E-700’s superior expression.

- 160 W output into 1-ohm load (music signals)
- High damping factor of 1,000
- Strong power supply with high-efficiency toroidal transformer and large filtering capacitors
- Protection circuitry using MOS-FET switches
■ Power amplification stage that achieves linear output
The power amplification stage on both the left and right sides features a large heat sink and employs four-fold parallel push-pull power transistors driven in Class A to provide linear power output of 35 watts into 8 ohms, 70 watts into 4 ohms, and 140 watts into 2 ohms.
■ Power supply circuitry delivers steady power
A strong power supply featuring a massive toroidal transformer and two high-voltage, large filtering capacitors (56,000 μF/50 V) offer a stable power supply at all times.
■ High damping factor brings out the full potential of speakers
The damping factor represents the amplifier’s ability to drive the speakers. A damping factor of 1,000 (guaranteed) extracts the maximum potential from the loudspeakers.
