Harman/Kardon AVR 347

Stereo and surround delights

  1. Harman/Cardio AVR 347
  2. Data sheet

The Harman/Kardon AVR 347 for 1000 euro not so openly shows his dual channel affinity. Despite the seven stages there is no bi-Amping option (the two rearmost channels can interconnect but a second room), also a “Pure Direct” button does not exist. AVR 347 constantly needs his DSP, for each input can be configured individually bass management including. For CD operation, you could simply turn off the subwoofer. The bass portions then take the front speakers. The subwoofer is again ready for the impact of video DVD sound.

Hearing test

The surround listening passage brought surprises. Because the direct predecessor of AVR 347, the Harman/Cardio AVR 340 (900 euros), which compared proved a strong opponent. Exactly and grippy, with much authority he reproduced effects, voices and music. His younger brother 347 drew a tick less sharp contours, for he acted with comparable muscle strength, that particularly impressed if effect thunderstorm pattered down on the audience. Older Harman/Cardio AVR 340 sounded something wooden and hesitant – to brake, to fully explore subtleties. The new AVR 347 countered with a more dynamic, more open performance. He was especially rock pieces with much use of guitar masterfully. Only the comparison with the Denon AVR-2107 (75 stereo points) halted him.
