A new 2-channel preamp with Google CAST streaming capability

The amplification stages are all developments based on Class A designs while the output stage is a dual mono. The Densen B-250CAST has a dedicated Densen Cast power supply for the Google Cast receiver plus a dedicated optical input. Densen has even developed a dedicated power cord to connect Google Cast to the B-250CAST preamp along with a  Toslink cable to complete the setup which is also optimised for use between the unit and Google Cast.

Other details include the volume control, which is controlled by a Vishay metal film resistors model, switched by relays and controlled by the microprocessor, containing 200 steps. The B-250CAST also contains a socket for the DP-07 MM RIAA stage. There is also the possibility of upgrading the B-250CAST with the DNRG, 1NRG or 2NRG external power supply.
