Pioneer A-9

In addition to the striking design, the new stereo amps offer much sound.

  2. Data sheet

Au carry all two amplifier A-series of course phono Preamps on board, the A-9 even for moving magnet and moving coil phono cartridge. The joy clouded however a first check with the MM-pickup gold ring 1022 GX. Especially over the A-9, which sounded insubordinately shrill and dull at the same time. The measurement laboratory clarified: the input capacities are with 454 (A-6), but especially 1820 Picofarad (A-9) much too high. Who seeks a balanced reproduction of records, which should either connect an high-output MC system or at the A-9 use the pleasing noise MC input.

Then, the pioneers with dynamically widely flared, sound-color very balanced game – reward him balanced in comparison. Because 6 could not settle by the A A 9. The reason was A 9, but a strong A-6 but not a weak.

Compared to the EUR 500-expensive brother A 6 of 800 Euro amplifier equipped with order speaker terminals A-9 is a also audio signals via a USB interface – the career of iPod & co. as a serious stereo music sources is just not stopping.


The A9 justifies the extra price compared to the A6 by the additional equipment
