The high current capacity of the P-7300 is critical to its ability to deliver exceptional audio performance.
The amplifier of power
The Accuphase P-7300's power amplifier is a highly sophisticated design that employs a fully balanced circuit configuration with complementary dual FETs in the input stage. This enables a low-noise, high-gain operation with exceptional clarity and detail. The power amplifier also includes a one-of-a-kind three-stage Darlington circuit with high-speed power devices for high output with minimal distortion. Because of this advanced design, the P 7300 produces precise and powerful sound with a wide dynamic range.
Push-pull 10 parallel
The P-7300 Accuphase power amplifier has a one-of-a-kind 10-parallel push-pull configuration that allows it to produce a powerful and dynamic sound while maintaining excellent control and stability. This advanced design parallelizes ten power devices for each channel, significantly increasing output current capacity and reducing distortion. The P-7300's 10-parallel push-pull configuration also ensures that it can easily drive even the most difficult speaker loads, delivering deep, impactful bass and clear, detailed highs.
Amplification
The P-7300-Accuphase power amplifier employs a Class A/B amplification circuit, which combines the best characteristics of Class A and Class B amplification. The Class A/B circuitry ensures that the amplifier operates in Class A mode until a certain output level is reached, resulting in a pure, natural sound with low distortion. When the output level exceeds a certain threshold, the amplifier enters Class B mode, increasing efficiency and lowering heat generation. The P-7300's advanced amplification design allows it to deliver exceptional sound quality while conserving energy.
Instrumentation amplifier with low noise
In its input stage, the Accuphase 7300-P power amplifier includes a low-noise instrumentation amplifier, ensuring a high level of accuracy and precision. This advanced design achieves an exceptionally low noise floor through the use of high-quality components and a fully balanced circuit configuration, resulting in a clean and detailed sound. The instrumentation amplifier also includes a differential amplifier circuit with a high common-mode rejection ratio to reduce unwanted noise or interference in the signal path. This design is crucial to the P-7300's exceptional sonic performance.
Excellent audio quality
Because of its advanced circuit design and high-quality components, the Accuphase P-7300 power amplifier is known for its exceptional sound quality. The P-7300 delivers a pure and natural sound with low distortion and outstanding clarity thanks to its low-noise instrumentation amplifier, 10-parallel push-pull configuration, and Class A/B amplification circuit. Accuphase's patented AAVA volume control is also included in the P-7300, ensuring precise and linear volume adjustment. The Accuphase P-7300's powerful and dynamic sound, combined with its sleek and stylish design, make it a top choice for audiophiles who demand the best in sound quality.
