Bring out accurate reproducibility
To solve the hard sound of CD players
Yamamoto Sound Craft YDA-01 is a DA converter designed with the clear goal of ``solving the harsh sound of CD players.'' A thoroughly simplified circuit and careful power supply design bring out fresh, vibrant sound from digital sound sources, achieving accurate reproducibility.
Simple output circuit with one transistor
- Circuit simplification: Based on the conclusion that ``the simpler the circuit and the fewer elements it passes through, the better the sound quality'', the output circuit uses a base grounded, non-feedback single system with a single transistor.
- Super simple configuration: With only one transistor and one resistor, it has a very simple configuration that converts current output to voltage and also functions as an output circuit. This circuit makes the sound quality very natural, creating a sound that is fresh and full of dynamism.
Luxury monaural parallel configuration of PCM1794A
- Pursuing the best performance: The high-performance PCM1794A is used as the DA converter IC, with **one L/R channel each in monaural mode**.
- Energetic sound: This monaural/parallel configuration delivers powerful, energetic sound with no interference between channels, bringing out the best in performance.
Thorough power supply circuit andHigh-Fidelityparts
- Independent power supply circuit: Adopts a large-capacity toroidal transformer and separates analog and digital windings. Furthermore, by making the digital section, analog section, and output circuit independent and supplying them from separate regulators, interference with the circuits by the power supply is eliminated.
- Highly reliable wiring material: The wiring material uses Teflon insulation and silver-plated copper wire, which are extremely reliable and have excellent sound quality, ensuring a high S/N ratio and sound purity.

Fresh and lively sound
"Solves the hardness of CD player sound and brings out accurate reproduction."
The development goal of "solving the hardness of CD player sound" has been achieved, and the YDA-01 is evaluated for producing an extremely natural sound with reduced digital harshness and artificial nuances. As a result, it delivers sound that is fresh and full of vitality, making the music come alive.
「"Pure sound freshness provided by a single-transistor output circuit."
The simple single-transistor, common-base, no-feedback single-output circuit is notable. This design, which reduces the number of components to maximize sound purity, ensures high-purity, fresh signal transmission and contributes to a sense of liveliness in listening.
"Energetic and powerful sound through monaural parallel configuration."
By using a high-performance PCM1794A in monaural mode for L/R channels separately, channel interference is eliminated, producing powerful and energetic sound. This thorough independent configuration of the power supply and DAC provides high S/N ratio and excellent resolution.
