Pro AV CD77 Top Loading Tube CD Player

Pro AV CD77 Tube CD Player
Top-Loading Design with Vacuum Tube Warmth & High-Resolution DAC

The Pro AV CD77 is a top-loading tube CD player that delivers the warmth of analog with the clarity of modern digital technology. Designed for audiophiles who appreciate musicality and engineering excellence, the CD77 combines premium components with elegant simplicity.
At the heart of the CD77 is the Cirrus Logic CS4398 24-bit/192kHz DAC, renowned for its high-resolution audio decoding and wide dynamic range. The digital control is managed by the Philips SAA7824 servo chipset, providing precise and stable CD tracking and error correction—crucial for faithful playback. This works in tandem with a Sanyo high-precision 3U optical laser lens, ensuring accurate disc reading even on older or imperfect CDs.

The analog output stage features two 6H3 vacuum tubes, delivering a rich, smooth sound with a natural midrange and tube-like warmth. Internally, the player is powered by eight independent regulated power supplies, which isolate critical circuits and minimize interference, preserving audio purity.
The top-loading mechanism with metal disc puck and anti-vibration aluminum chassis ensures mechanical stability, while the upsampling feature allows CDs to be played at 88.2kHz or 176.4kHz, enhancing resolution and detail. With both analog RCA outputs and digital coaxial/optical outputs, the CD77 integrates effortlessly into modern and vintage audio setups.
With its balance of premium tube audio, precision digital engineering, and solid construction, the Pro AV CD77 is a powerful and refined source component for discerning music lovers.
