You will recognize once you listen. The sound will be more clear and natural throughout entire range with RSP-901EX. You could feel and experience more realistic sound with a full of musicality. In a word, you could be convinced that the RSP-901EX brings out fully potential of your audio system. RSP-901EX is not only an audio-accessory but also a real audio-gear for improving the sound quality of your system dramatically.

Technical explanation

When the amplifier drives speaker, at the same time, speaker generates counter-electromotive force. This is because the speaker operates according to the same principle as a motor. This counter-electromotive current returns to the amplifier via the speaker cord, making it difficult to drive speaker in accordance with the input signal.
It is because this current makes negative effect to the feedback loop causing complicated phase delays. This physical phenomenon hurts the sound quality of the audio system.
Absorbing the part of counter-electromotive force by RSP-901EX, the amplifier can drive the speaker more easily. This enables more accurate speaker drive, and it can reliably reproduce fine signals. Musicality is expressed by delicate and fine signals. RSP-901EX plays the sound with Musicality by reliably reproducing those fine signal.
