Densen has over the years produced many well respected preamplifiers, the DM-20, B-200, B-250 and B-275 to name a few. Now Densen introduces the B-230CAST, a new high end preamp with streaming capability at an affordable price. Taking many of the innovations from the B-275 Super Leggera preamp, the B-230CAST offers a new level of performance.
The B-230CAST 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 today, the difference is even more substantial. Digital volume controls typically uses FETs for their regulation, and has signal paths with up to 600 components inside the IC. As such, they lack transparency and detail level. This the B-230CAST microprocessor controlled attenuator has in spades!
The B-230CAST contains a socket for the DP-07 MM RIAA stage. There is also the possibility of upgrading the B-230CAST with the DNRG, 1NRG or 2NRG external power supply to further enhance the sound quality to experience truly breath-taking 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 (90.000 uF) that would make most other power amplifiers envious. This design produces a musicality which is truly outstanding by any standards. It contains a separate transformer for all the digital circuits. In addition it contains separate regulators for the various digital stages, like display, microprocessor and streamer. It also contains a very powerful PSU for audio, with separate regulators and capacitors for each channel.
Audiophile GOOGLE CAST streaming.
Using the GOOGLE ChromeCAST Audio receiver, the Densen B-230CAST has a dedicated Densen CAST power supply, which is an extreme low noise PSU, to secure that the GOOGLE ChromeCAST Audio has perfect working conditions. On top of that, the Densen B-230CAST has a dedicated optical input, allowing the GOOGLE CAST to perform at its best, with the highest possible data quality. Densen has even developed a dedicated power cord to connect the GOOGLE CAST to the B-230CAST preamp. This power cord is shielded, to avoid interference, and securing an optimal performance. Further Densen developed a Toslink cable to complete the setup, and naturally, this optical cable is optimized for use between the GOOGLE ChromeCAST Audio and the B-230CAST.
One of the great benefits of the Densen B-230CAST design is, that Densen has avoided creating their own software. It is well known fact, that High end manufacturers often faces problems with own software, as the computer and phone manufacturers develops new software, that is incompatible with the high end manufacturers streaming software.
The digital signal from the GOOGLE CAST is converted to analogue using the built in DAC of the CAST AMP. This DAC is based on Densen’s experiences with DAC designs, which traces back to 1996, where Densen designed their first DAC as an OEM product for a well-respected European High End manufacturer. The CAST AMP DAC allows 24/192 and as such is capable of higher resolution than GOOGLES CAST delivers, this allows for future upgrades of the GOOGLE CAST technology with ease. The B-230CAST DAC has a gain selector, which secures high resolution when setting the gain from low volume up to full party mode! Further the B-230CAST preamps DAC is using a DAC chip encapsulated in a shielding box, to minimize interference, and optimizing performance. It uses dedicated high performance components like Vishay metalfilm resistors and capacitors chosen for their sonic superiority, including Densen’s own power supply capacitors. The analogue stage is naturally a discrete design, using ultrafast transistors, and works in Class A. Naturally, this DAC can be upgraded if needed, without having to change the complete B230CAST!
The Densen B-230CAST is done with all the usual Densen focus on even the smallest parameters of the design. The
B-230CAST has a build in mains filter, that does not raise the impedance of the mains, and as such does not slow down the power supply, but at the same time, it makes sure, that there is no DC in the mains AC supply! The 2 transformers are encapsulated, to avoid vibration interfering with the audio circuit. The power supply capacitors are all Densen Custom Made Capacitors. The analogue stages are made with ultrafast transistors, high quality capacitors, and Vishay metalfilm resistors. Densen has focussed on making the signal path as short as possible, while at the same time, avoiding interference from each part of the circuit. All components are surface mounted with a precision of 0,02mm! The circuit board is Teflon isolated, the input terminals are all selected for their sonic superiority, as they lead the signal from the cable directly down to the circuit board signal path with only 1 solder. The solder is silver base, and all solderings are done in an atmosphere of nitrogen, to avoid oxidation of the solderings, which over time, would have resulted in degradation of the sound!
As always with Densen, the sound has top priority, and as such, the B-230CAST offers a strong musical performance in line with the traditions of Densen. Dynamics, transparency, detail level, soundstage, precision and musicality is outstanding, and using the B-230CAST will allow the user to delve into the music, and forget about the technology in the quest for audiophile nirvana!
