Audio Research Reference 3

Audio Research Reference 3

  • Descriere Produs

    • Audio Research Reference 3 is a 'Breakthrough'. Audio Research Reference 3 is so good that it is startling when you hear it in your system. Audio Research Reference 3 is more musically transparent. It presents an immense soundstage that makes everything else sound one-dimensional. Voices and instruments have real body and weight, with pinpoint focus. The deep, powerful bass is fast, articulate, and controlled. Audio Research Reference 3 possesses a dynamic swing that is breathtaking. And, most importantly, there is a directness and immediacy that connects the listener with the performance. The results are simply thrilling.
      The remarkable level of performance has been achieved with all new audio and power supply circuits. There are four new circuit boards and two new transformers. The new audio circuit is pure tube, Class-A, with zero feedback, utilizing a total of four long-life 6H30 twin triodes. FETs are used for constant-current sources (outside the single path), and the analog circutry uses a long-tailed pair input stage to provide the same performance in either single-ended or balanced operation. Total gain is 12dB balanced, 6dB single-ended. The hybrid power supply has over 50% greater energy storage that its predecessors, greatly contributing to its tremendous dynamic capability. There are other improvements which can be seen on the bench and appreciated in the listening room. Bandwidth has increased from 60kHz to 200kHz; noise has been reduced by 12dB; headroom is much higher, with the maximum input increased to 20V balanced, and distortion has been lowered by 40%. The advancements of the Audio Research Reference 3 are both audible and measurable.
