Accuphase E-700

An integrated amplifier crafted from the technology used in our flagship model

The E-700 is an evolutionary integrated amplifier that incorporates numerous technologies from our 50th anniversary flagship model, the E-800. The pre amplifier 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.

Accuphase A-80 Class A Stereo Power Amp

Accuphase A-80

Class A Stereo Power Amplifier

The A-80 is a stereo version of the 50th anniversary model A-300, and is a pure Class A stereo power amplifier that pursues reduced output impedance and constant voltage drive to bring out the full potential of the speakers. It is a flagship model. The power amplification stage uses 10 parallel push-pull class A operation using power MOSFETs, achieving linear high power outputs of 65W/8Ω, 130W/4Ω, 260W/2Ω, and 520W/1Ω. In addition, noise performance has been improved by using an ``instrumentation amplifier'' whose signal input section is composed of a balanced circuit, ``ideal gain distribution'' between the signal input section and power amplification section, and ``MCS+'' which is a two-parallel circuit. has been raised to the maximum. Additionally, a damping factor of 1,000 has been achieved by reducing output impedance through balanced remote sensing and semiconductor switches. In addition, it is equipped with a protection circuit that prevents short-circuit accidents of the speaker terminals, so you can use it with confidence.

Please appreciate the alluring sound of A-80 which will be an object of aspiration for the audiophiles.

Accuphase DP-770 MDSA SA-CD Player

Accuphase DP-770

PRECISION SACD-CD PLAYER

The compact disk is proving resiliant to the relentless march of technology, a situation fortold by the premature burial rites inflicted on the venerable Vinyl LP audio system some 30 years ago now. Quite simply folks are appreciating the certainty, security and joy of actually owning their favourite music, in physical form, in their own homes. If you are even slightly interested in the quality of the playback equipment then you should be keen to experience and own one of Accuphase's fabulous players.

And there is none more fabulous than the DP-7XX series, the flagship single box player in the range. The Accuphase DP-770 being the most recent incarnation. As an owner of a DP-750 I won't be upgrading, that would be silly, but if i didn't have one the DP-770 would head the list, it is simply that good.

Accuphase C-2300 Precision Stereo Control Centre

Latest New Release

Accuphase C-2300

The new C-2300 is an entirely new model that integrates the C2000 series, the standard for separate systems, and the C-2400 series, which has gained tremendous support from music lovers as a middle-class pre-main amplifier.

C-2300 has the "Balanced AAVA" volume control circuitry in the higher-end C-2900. In addition to the low and high frequencies, a new 4-band tone control allows adjusting the mid-low and mid-high frequencies, providing greater flexibility in adjusting the bandwidth balance. Expandability is also enhanced with two slots for the AD-60 Phono equalizer board and the DAC-60 Digital input board, making it compatible with various sound sources.

Enjoy your favorite music to your heart's content with C-2300, which has evolved by combining outstanding circuit technology with new features!

Accuphase PS-550 Clean Power Supply

Accuphase PS-550

Clean Power Supply

One has to go back in time a very long way to experience recorded audio without the benefit of electrical power. Indeed electrical power is fundamental to every home audio system, in my opinion only second in importance to the actual recorded music, and then only by a small margin. What most people fail to realise is that the energy that flows from a wall socket is really a "Power Signal". This power signal should be 50Hz and the figure is well within the Audio band. The nature of our power generation, distribution grid and varied load characteristics results in a horribly polluted 50Hz Power Signal. Additionally this signal is actually altered by the huge number of power factor modifying loads it is required to drive. This polluted and corrupted power can easily and usually does adversely effect the quality of audio a system can deliver. There are solutions and this Accuphase PS-550 Clean Power Supply is one worthy example.

Parasound Zphono Phono Preamplifier

$575.00

Parasound Zphono

The Parasound Zphono is an well thought out entry phono stage. Single ended (RCA) inputs and outputs, able to handle both MM and MC cartridges. Unusual for an entry level phono stage is the lack of the wall wart power supply. This unit takes it's power full strength, via the usual IEC socket. A reversible AC polarity switch helps with any system miss-match that can induce mains hum.
A neat, high performance and versatile entry level phono stage. Highly recommended. We have one on demo.
