Default Sparkler Audio S507 CD player

Just in now!

S507 top loading mechanism-like analog CD players

Inheriting the sound quality of the model S303A "notebook CD Player", this new model also has a non-oversampling D/A converter built in at a minimal size, and is finished as an integrated CD player.

From our investigations, we successfully improved the technology to further reduce the noise level, enhancing the fine expressive power. S507 is compatible as a high-end CD transport, where two digital output types (S/PDIF, I2S) are supported: CD transport type (S507t) with or without built-in DAC. As for the built-in DAC models, there are two types of signal modes available: conventional voltage-mode (S507v) and a new approach current-mode (S507i). Once you listen to the sound quality of current-mode (S507i), you will never forget the sound quality!

How does the voltage-mode and the current-mode work?

By adopting superior current-mode signaling in exchanging audio signals, dramatic progress is made from the conventional audio system to significantly improve the purity of the sound quality.

To use current-mode type (S507i), you need a current-mode amplifier, such as S502i and S505i.
