AV SHACK 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.
