Stiprintuvas PIONEER A-70DA

The A-70DA, which weighs more than 17 kilos, is not just about mass, it is above all about class: Separate mains transformers for pre-amplifier and amplifier sections, above all when they are individually cast and shielded as here, provide not only weight, but also working conditions with unsurpassed low interference for the audio circuitry. The doubled A-70DA is worth it because its pre-amplifier has a completely symmetrical layout. An individual, particularly low-loss loudspeaker volume control was even integrated for the symmetrical XLR input. Via its digital inputs the A-70DA is equipped for all modern music formats. In this respect, the very highest resolutions, such as Quad-DSD (11.2 MHz) and PCM with 384 kHz and 32 bit, are supported via USB. The high-resolution counterparts in the analog world are exclusive MC pick-ups which, thanks to the a switchable phono stage, supply this top model just as precisely as the widespread MM systems. With its doubled chassis, the full-metal loudspeaker knob and the thick aluminium front and side panels, the casing guarantees a suitably high-class performance.
