Accuphase A-250 CLASS-A MONOPHONIC POWER AMPLIFIER

Accuphase A-250 CLASS-A MONOPHONIC POWER AMPLIFIER

The A-250 encompasses Accuphase power amplifier know-how to the fullest. It is destined to become another milestone, taking the art of audio to the next level. In order to realize ideal speaker drive capability, the A-200 employs a structural design that exceeds even the M-6200. Two completely separate power amplifier units, each with its own dedicated heat sink on either side of the chassis, are driven in parallel.
Another outstanding characteristic of the A-250 is its enormously improved S/N ratio. By adopting the advanced instrumentation amplifier principle for the input stage in a double configuration, using only discrete electronic components instead of ICs, and fine-tuning the gain complement with the following stage, simply amazing S/N ratings were achieved: 126 dB at the maximum gain setting and 132 dB with gain set to –12 dB. These represent ultimate values even in the formidable Accuphase lineup.

Accuphase A-36 CLASS-A STEREO POWER AMPLIFIER

Accuphase A-36 CLASS-A STEREO POWER AMPLIFIER

The new A-36 inherits many of the outstanding design technology features developed for the higher-end models. It redefines the baseline for pure class A power amplifiers and represents the same unwavering attention to detail and dedication to sound quality for which Accuphase is justly famous.
In the output stage, power MOS-FETs renowned for their excellent frequency response, sonic performance, and superior reliability are used in a triple parallel configuration and driven in pure class A. This is sustained by the strong power supply featuring a massive transformer and two large 47,000μF filtering capacitors. Output power in each channel is rated for an impressive 150 watts into 1 ohm, 120 watts into 2 ohms, 60 watts into 4 ohms, and 30 watts into 8 ohms. Even speakers with ultralow impedance or drastic fluctuations in impedance curve can be driven reliably by this impressive amplifier.
In the output circuitry, MOS-FET switches are used in place of relays, to eliminate mechanical contacts and improve long-term reliability.

Accuphase M-6200 1,200W/1Ω MONOPHONIC POWER AMPLIFIER

Accuphase M-6200 1,200W/1Ω MONOPHONIC POWER AMPLIFIER

The M-6200 approaches the concept of the power amplifier from a new vantage point. It achieves an unprecedented level of performance that again redefines what a monophonic power amplifier can be. Retaining the parallel arrangement of two completely identical amplification circuits, the M-6200 drastically lowers the noise floor and improves the damping factor. Parallel operation has the advantage of significantly bolstering output current capability, as well as enabling extremely low output impedance. Furthermore, improvements to the NFB circuit using remote sensing and other technological refinements result in a damping factor in excess of 1,000 and make the amplifier capable of delivering constant current down to extremely low impedance loads. In the input stage, parallel operation along with optimized gain allocation keeps noise levels to an absolute minimum, as illustrated by the astonishing S/N ratio of 127 dB at maximum gain and 133 dB at the -12 dB gain setting.

Accuphase P-4500 STEREO POWER AMPLIFIER

Accuphase P-4500 STEREO POWER AMPLIFIER

The quest for the optimal power amplifier has just taken another giant leap forward. The P-4500 features an instrumentation amplifier configuration realized with discrete semiconductors in the signal path, triple Darlington 4-parallel complementary push-pull architecture and many other technology advantages. The result is an impressive S/N ratio of 121 dB, rated output of 500 watts into 1 ohm (music signals), and a damping factor of 700. A newly developed output protection circuit can also detect any short-circuiting of the speaker terminals, for complete peace of mind. This power amplifier is the ultimate tool for immersive music enjoyment on the highest level.

Accuphase P-7300 STEREO POWER AMPLIFIER

Accuphase P-7300 STEREO POWER AMPLIFIER

The P-7300 inherits technology features and concepts of the 40th anniversary commemorative model A-200 and subsequent M-6200 and takes these even further. Some of the highlights are a drastic reduction in noise and a significant further improvement of the damping factor.
In the final stage, the parallel configuration of output devices ensures high current capacity and keeps the output impedance of the power amplifier extremely low. In addition, intensive research has culminated in an improved NFB loop with remote sensing, and the use of MOS-FET switches characterized by low ‘on-resistance’.
This further improves the ability to handle any speaker with competence, realizing constant-voltage drive even with extremely low load impedances. The guaranteed damping factor of at least 1,000 demonstrates the impressive success of this approach. In addition, by further refining the parallel drive and gain allocation of the input stage, Accuphase engineers were able to push the noise floor to previously unthinkable levels, achieving an amazing signal-to-noise ratio of 125 dB at maximum gain and 131 dB at the –12 dB gain setting.
