Integrated Digital Amplifier

A Superb Series Offering Dedicated Audio Engineering with Versatile Music Playback

Without a doubt, digital technology is making some noise in the audio industry. But rest assured that any noise -particularly signal noise - is noticeably absent from the A-933 integrated amplifier and C-733 CD player thanks to Onkyo’s commitment to promoting the cleanest signals through its proprietary technologies like VL Digital, VLSC (Vector Linear Shaping Technology) and Direct Digital Path. The A-933’s dual toroidal power transformers and thick bus plate support a large, stable flow of current and also work to reduce impedance. The C-733 CD player’s impressive engineering enables a super signal-to-noise ratio ensuring supreme playback quality. Capping off this series is the T-433 FM/AM RDS tuner, which uses RDS and Accuclock to deliver radio frequencies that will surprise you with their precision and clarity. Use these componentsas they best meet your needs.
