Product Description

Pioneer A-70DA is about more than mass with separate mains transformers for pre and power amplifier sections individually cast and shielded as well as low interference for the audio circuitry. With its doubled structure, full-metal loudspeaker dial and thick aluminium front and side panels, the casing ensures a suitably high-grade performance.                                                                                                                                         

Fully-Balanced Preamp Circuitry

With isolated L/R symmetrical design and fully-balanced circuitry, the preamplifier allows incredibly pure signal input to the output stage for the Class D amplifier. This enables a signal augmentation fully employing the brisk and powerful drive of the amplifier. Connect with a balanced output unit such as Pioneer’s N-70A network audio player or U-05 USB-DAC with headphone amplifier, and you are sure to gain unprecedented high-resolution and high S/N reproduction with least transmission loss. Experience pure audio localisation and the rich expanse of the sound field, as every vocal springs to life with awe-inspiring presence.

High-Fidelity Class D Amplifier

Pioneer boasts unrivalled experience in digital amplifiers. The Class D amplifier enables flexible circuit layout and patterning for optimal design within the bounds of construction. With multiple original parts aiding effective operation, the component fully exploits the Class D amplifier to produce refreshing, pure sound with subtle details usually missed by analogue amplifiers.

Analogue Balanced Input (XLR)

Highly popular NEUTRIK terminals are employed for analogue balance input (XLR3) attaining high-res sound by quality signal transfer to the pre-amp with fully-balanced circuitry design. The “hot” utility can be switched between pin 2 and 3.

Twin Transformers in Shield Cases

Twin transformers minimise the noise in the minute signal area from transmitting to the primary side of the power amp block where it can drastically affect sound quality. The transformers are shielded in individual blocks with infill to lower leakage flux from the transformer.


Top-performance 8-channel ESS SABRE32 Ultra DAC is employed and features low noise and high Signal-to-Noise ratio that enables 4 channel parallel driving for each at up to 384kHz. This leads to clean and open yet robust sound with first-class audio quality.

384 kHz/32-bit USB-DAC 

The integrated amplifier enables direct USB linking with a PC.  USB asynchronous signal transfer mode regulates the transfer process via its high-precision clock guaranteeing high-quality audio reproduction. This removes jitter replicating master quality sound with incredibly precise audio signals. On top of 11.2 MHz DSD, the unit facilitates LPCM with sampling freq of 44.1-384kHz and bit rate of 16, 24, and 32 bits.

Aluminium Styling

Aluminium panels are used on the front and sides with thick 3.5mm front panel and 1.8mm side panels granting rigidity for a balanced performance. The machine-cut volume knob affords a solid, high-quality feel and style.
