Onkyo A-9555

The high efficiency (90%) of digital amplification also benefits the more compact design for today’s homes.

With this integrated amplifier, sound quality takes the lion’s share. By using Onkyo’s exclusive VL (Vector Linear) digital technology to eliminate all noise before it introduces timing inversion errors, it is possible to achieve highly accurate analog-to-digital conversion.

Also, at the heart of the A-9555 is the “Pure Stream Power Supply” – essentially a large power transformer – which ensures that the user will always have the necessary power for clarity and level of detail regardless of the type of music.
