Digital / Analog Converter Advance Acoustic MDA 503

Anyone looking for a converter for CD sound, atmospheric MP3 playback and distinctive sound of radio, which is powered by the advance acoustic MCD 503 (850 euro) very well.

  1. Digital / analog converter advance acoustic MDA 503
  2. Data sheet

The MDA 503 charged the scale with 13 kilograms, a sign for local processing. An all-metal body, the massive aluminum front panel and cone feet brace themselves in the way Microphone. Under the sheet metal cover, there is a strict division of labour. One of two toroidal transformers declared responsible for the ‘analog’ staff, second feeds the digital team. It consists exclusively of members of the PCM group. By USB wants to know the MDA 503 partout nothing.

Instead of that accept the input receiver module in the MDA 505 all possible sampling rates from 32 to 192 kHz. He sends the audio bit blocks extracted from the digital signal without more time and bit conversions to two prestigious stereo D/A converters: the 192 kHz-24-bit converter AD 1955 are also found in the Lavry since 11.

At the (balanced) analog signal amplification, advance acoustic brings two tubes (double Triodes 12 AX 7 from China) in the game. Transistors stuck up for the subsequent impedance conversion; the Asymmetrating achieved an op-amp called 5532.

The C 60 (62 points) was 4/09 tested tubes CD Player T.A.C. CD listening test with CDs in stereoplay but something taken too high – against the lustre of the heights and the plastic floor drawing of the player had to fit the separate converters. In the tested 9/08 benchmark, he found a similar opponent. The DAC 1 pre played something wuchtiger the advance acoustic was, however, with Three-dimensional structure and more fluid. Anyone looking for a converter for CD sound, atmospheric MP3 playback and distinctive radio sound, which is supplied by the MCD 503 perfectly.
