Leben CS-300F integrated amplifier – Ολοκληρωμένος Ενισχυτής με Λυχνίες
The Leben CS-300F is an integrated amplifier with 15 watts of tube power – through the GE JAN-6197 valves previously used only for computers (JAN – Joint Army and Navy).
They are low distortion and long life valve that Leben sourced many years ago and have been seeking the best circuit design to bring out the best performance in this clean tube.
The driver circuit utilises a very high quality tube, the 17EW8 (Hi-Fi) produced specifically for hifi by a major Japanese electronics manufacturer.
The result – a nice full sound and the bonus of a very high quality headphone output.
Difference between CS-300F and CS-300XS: The main difference between two models is the sound characteristics due to different output valves.
The sound of CS300F is more modern and clear whereas and the sound of the CS300XS is more valve-like (tube-like) / warmer, therefore a choice can be determined based on your own sound preference.
