High-output integrated amplifier featuring Balanced AAVA

The E-5000 is the flagship high-power Class AB integrated amplifier developed to mark Accuphase’s 50-year anniversary. The pre amplifier section features our superior Balanced AAVA volume control, while the power amplifier section includes an instrumentation amp and power transistors in a five fold push pull arrangement driven in Class AB. These circuits create a balanced circuit from input to output. With its precisely balanced circuits and solidly built output stage, the Accuphase E5000 integrated amplifier presents every piece of music in exquisite detail

Balanced AAVA volume control. Conventional pre amplifiers use variable resistors to adjust volume, which causes contacts to deteriorate and create grit as well as increase noise at normal volume levels. AAVA, however, produces multiple, widely varying signals from the input signal and controls volume by changing the combination of those signals. This achieves minimum noise at all volume levels without any grit. The E-5000 with its balanced AAVA circuits delivers exceptional noise suppression performance.

Quiet and smooth volume sensor design. The AAVA controls the volume levels by using its volume sensor to detect the position of the volume knob and then changing the combination of those signals. Accuphase developed the volume sensor in-house, using robust and heavy materials and crafting it using an aluminium block extrusion process to achieve smooth operations, a solid operation feel, and precise position detection when rotating the knob. It also suppresses operation sounds when using the Remote Commander to allow for quiet and pleasant volume adjustment.

Formidable power amplification stage. The power amplification stage on both the left and right sides is equipped with a large heat sink and employs five fold parallel push pull power transistors driven in Class AB to provide rated, high power output of 240 watts into 8 ohms and 320 watts into 4 ohms.

High damping factor brings out the full potential of the loudspeakers. 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.

Power supply circuitry designed for optimum stability. A strong power supply featuring a massive toroidal transformer and two high voltage, large filtering capacitors (40,000 μF/100 V) offers a stable power supply at all times.

Testimonials

Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.

The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.

It’s now two weeks since I bought home my new system and I wanted to say thanks again for all your help, advice and guidance, not to mention cups of tea. I now have a system that meets all my requirements and sounds fantastic. Special thanks to Jon, who I hope is on the road to recovery from his operation and to Roger, who helped me finalise my choice. The Rega Saturn, Hegel H190V and Dali Rubicon 2 is undoubtedly the best system I have ever owned.
