The Densen B-250 has established itself as a reference pre-amplifier on the high end market over the years. Now Densen introduces the B-250CAST. Taking many of the innovations from the B-275 SuperLeggera pre-amp, the B-250CAST offers a new level of performance from the renowned B-250. The B-250CAST is filled with advanced solutions, which all share the goal of giving you even more musicality.
The volume level is controlled by an extremely precise attenuator made of Vishay metal film resistors, which is switched by relays controlled by the microprocessor. In comparison with a normal volume potentiometer of the kind used in the majority of all preamps, the microprocessor controlled attenuator has virtually no self induced noise and an extremely low distortion. This results in an unsurpassed precision and refinement, and the attenuator contains no less than 200 steps!
This makes it possible to adjust the volume very precisely (0.5dB) even when the sound is so low that an ordinary volume control would create an uneven balance between left and right. Compared to the popular digital volume controls used in many amps now a days, the difference is even more substantial. Digital volume controls typically uses FETs for the regulation, and has signal paths with up to 600 components inside the IC. As such, they lacks transparency and detail level. This the B-250CAST microprocessor controlled attenuator has in spades!
