Pioneer A-70DA Integrated Amplifier
Ooberpad presents the Pioneer A-70DA Integrated Amplifier which weigh more than 17 kilos. We’re talking about pure class over here. There are separate main transformers for pre-amplifier and amplifier sections, and above all when they are individually cast and shielded, they provide susceptible working conditions with unsurpassed low interference for audio circuitry. The doubled A-70DA is worth every single penny because its pre-amplifier has a symmetrical layout. An individual, particularly low-loss loudspeaker volume control has been brought in for the symmetrical XLR input.
The A-70DA through its digital inputs is thoroughly equipped for all modern music formats. Keeping this in mind, the very highest resolutions, such as Quad-DSD ( 11.2 MHz) and PCM with 384 kHz and 32 bit, which are both supported via USB. The highest-resolution counterparts in the analog world are exclusive MC pick-ups which owing to the switchable phono stage, supply this top model just as amazingly as the widespread MM systems. With the help of its doubled chassis, the full-metal loudspeaker knob and the thick aluminium front and side panels, the casing here guarantees a high-class performance.

Benefits of Pioneer A-70DA Integrated Amplifier :
The Latest High-Fidelity Class D Amplifier
Pioneer has considerable advantage over other manufacturers with unrivalled experience in digital amplifiers. A considerable amount of research has gone into designing and developing this amplifier. Through extensive component reviews and research, the latest High-Fidelity Class D amplifier has been able to achieve improved transmission efficiency to reproduce sound that is finer in nature. It has downsized the circuit and heat sink by introducing the “Direct Power FET” with a high-efficiency drive for the output element, thereby significantly reducing electric signal loss and resonance noise. Additionally, it also enables the installation of a large-capacity power supply, which enhances the rapid production and control of the quick-responding sound unique to the Class D amplifier, allowing you to enjoy “dynamic low pitch” music.
Preamplifier with Fully-Balanced Circuitry
The preamplifier comes equipped with a full-balanced circuitry which enables high-resolution sound reproduction. The signals from the analogue balanced inputs are sent with high-grade balanced transmission, while directly delivering to the input stage of the High-Fidelity Class D amplifier as a result of which you can experience clear audio on your part with reduced noise. Moreover, you can also enjoy high-grade balanced connection with balanced output components, such as Pioneer’s N-70A network audio player and U-05 USB DAC.
Analogue Balanced Input (XLR3)
Analog balance input (XLR3) is achieved due to the highly renowned NEUTRIK terminals and this helps in achieving high-resolution sound by quality signal transmission to the pre-amplifier with fully balanced circuitry design. It comes with a provision for a “hot” function which can be switched between pin 2 and 3.
Twin Transformers in Shield Cases
The advantage of having twin transformers for the power amp and the preamp is that they help keep the noise in the small signal area from transferring to the primary side of the power amp block, where it can significantly affect sound quality. The transformers are placed in separate blocks with infill to reduce leakage flux from them.
Aluminium Panels and Knobs
Aluminium panels have been used on the front and the sides with extra-thick 3.5 mm front panel and 1.8mm side panels providing rigidity for a stable performance. The machine-cut aluminium volume knob gives a solid, top-notch feel and style. Moreover, the Input selector, Balance and Bass/Treble knobs are also made of aluminium.
