Densen has over the years produced many well respected preamplifiers,the DM-20, B-200, B-250 and B-275 to name a few. Then Densen intoduced the B-230XS which became an instead hit with Hi-Fi enthusiasts and Densen lovers alike.

Now Densen introduces the B-230CAST, a new high end preamp at an affordable price with streaming capability using Densens unique CAST technology allowing for easily connecting a streamer.

Taking many of the innovations from the B-275 Super Leggera preamp, the B-230CAST offers a new level of performance.


There are many reasons to fall in love with the B-230XS – here are just a few:

  • CAST-module with 1x high-res optical input and 1x USB power-output, allowing for easy connection to a streamer
  • 200 step relay controlled volumecontrol (0,5 dB steps)
  • Dual-Mono output-stage based on 6 watt pure class A amplifier with zero-feedback
  • Dual incapsuled toroidal transformers for optimal quiet performance
  • 1x 20VA power-transformer for microprocessor and display, and 1x 50VA power-transformer for sound-circuitry with seperate rectifiers and capacitors for each channel.
  • 90.000 uF capacitor bank made with Custom Densen capacitors
  • Expansionport for DP-07 phonoboard – turn your line-1 input into a phono-input.
  • Upgradeable with external powersupply (1-NRG, 2-NRG)
  • Designed in Denmark – Made in Denmark


The volume level is controlled by an extremelyprecise attenuator made of Vishay metal film resistors, which is switched by relays controlled by the icroprocessor. 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 signalpaths with up to 600 components inside the IC. As such, they lack transparency and detaillevel. This the B-250XS microprocessor controlled attenuator has in spades!

The B-230CAST contains a socket for a DP-07 MM RIAA stage. There is also the possibility of upgrading the B-230CAST with the 1-NRG or 2NRG external power supply to further enhance the sound quality to experience truly breathtaking musical experiences.

The amplification stages are all refined developments based on advanced Class A designs, which have been encapsulated on the board to avoid any kind of interference with the delicate signal. The output stage is a dual mono design with an extraordinarily huge storage capacity (100.000 uF) that would make most other power amplifiers envious. This design produces a musicality which is truly outstanding by any standards.
