Accuphase A-200
Recommended Retail Price: SGD$24,300.00 per piece
The A-200 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-6000. 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-200 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.
- Pure Class A operation delivers 100 watts of quality power into 8 ohms
- Two totally identical power amplifier units driven in parallel
- 20-parallel push-pull arrangement of MOS-FET devices in output stage delivers linear high power progression to ultra-low 1-ohm impedance
- Input section configured as double instrumentation amplifier
- Double MCS+ circuit and current feedback topology in amplification stage
- Support for bridged use of two A-200 units with even higher output power
- Strong power supply with massive high-efficiency toroidal transformer and large filtering capacitors

Accuphase M-6200
Recommended Retail Price: SGD$17,500.00 per piece
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.
- Two totally identical power amplifier units driven in parallel
- Output stage features novel high-power transistor devices in a dual 8-parallel push-pull arrangement
- Latest low-noise instrumentation amplifier technology
- MCS+ circuit and current feedback topology in amplification stage
- Support for bridged use of two M-6200 units with even higher output power
- Strong power supply with massive high-efficiency toroidal transformer and large filtering capacitors

Accuphase A-70
Recommended Retail Price: SGD$21,400.00
Inheriting many outstanding technology features of the A-200, the A-70 represents a full model change from the A-65, ready to take its place as the ultimate pure class A stereo power amplifier. While reflecting this tradition, the A-70 also implements latest technology such as the ultra low-noise instrumentation amplifier principle realized in a discrete configuration, along with optimized signal input and power amplification stages, resulting in an astonishing 127 dB S/N ratio (at -12 dB gain), surpassing even the formidable earlier Accuphase stereo amplifier lineup.
The output stage of the A-70 features power MOS-FETs renowned for their excellent frequency response, sonic performance, and superior reliability. In the output circuitry, ultra-heavy-gauge edgewise coils with a surface area more than three times larger than conventional units, combined with MOS-FET switches are used in place of relays, to eliminate mechanical contacts and improve long-term reliability. Top-grade materials, sophisticated circuit pattern technology, and various other measures result in low impedance and enable the realization of a damping factor of 800, which represents a two-fold improvement over the A-65.
- Pure Class A operation delivers quality power: 60 watts x 2 into 8 ohms
- Power MOS-FET output stage features 10-parallel push-pull configuration and delivers linear high power progression to ultra-low 1-ohm impedances
- Ultra low-noise instrumentation amplifier principle used in input stage
- Amplification stage implements further evolved MCS+ topology
- Current feedback principle combines stable operation with outstanding sound quality
- Bridged connection mode allows upgrading to monophonic amplifier
- Two selectable meter types: digital power meters showing true power values and bar graph indicators
