Densen DenDAC 50 NEW


The launch of a high end DAC from Densen Audio Technologies. Densen has a long history of designing DACs. The first Densen DAC was designed in 1994 for another well respected Danish high end company, which sold this Densen DAC under their own name. Since then, Densens design team, has been involved in designing DACs for several other companies. Now, comes the first full size Densen DAC under Densens own name, the Densen DenDAC 50. DenDAC 50 is a rare breed. Typically, if not allways, a DAC is these days designed with a digital volume control. However, this inevitably will lead to reduced resolution on low listening levels. DenDAC 50 uses instead a analogue Class A preamp stage, very similar to the preamp stage found in the Densen reference preamp B-275. 

The analogue stages are based on Densens famed 6 watt class A amplifier stage, with no negative feed back (neither global or local), which here is obvious used in a version with less than 6 watts output. 

It contains a relay driven attenuator, which is controlled by a microprocessor, and offer a resolution of 200 steps. In the digital department, Densen offers some rather unsual features. The DenDAC 50 has an internal port, that will allow to mount a small pcb with a digital input, in case there in the future comes some digital input standard which is currently not present on the DenDAC 50. This will also allow the implemention the fortcoming Densen WiFi board, that will receive digital signals by WiFi. Another option could be a blutooth receiver boad, but Densen does not have that in the pipeline at the moment. 

Besides that, the DenDAC 50 contains an USB input, 2 coax inputs and 2 toslink inputs.

The DAC is a new 24 bit type which is mounted under a shielded box, to avoid digital interference on the analogue stages. 
DenDAC50 has a carefull layout pcb layout in the digital domain, using a 4 layer PCB for additional optimazion of the signalpath, groundplanes and shielding of the signals. 

DenDAC 50 also contains 3 analogue preamp inputs. This allows analogue sources as Tuners, TVs, tapedecks etc to be connected to the DenDAC 50. The Tape output can also be used as line output to a headphone amp if so desired. The DenDAC 50 also has 2 headphone outputs. A classic Jack and a miniJack output, allows for all users of headphones to use the DenDAC 50 directly. 

Naturally the DAC has preout outputs from the DAC allowing connections to poweramps and other preamps. There is a fixed output, intended for preamps, and a variable output allowing for connection to poweramps. The variable output is naturally using the analogue preamp with the microprocessor controlled attenuator. 

Technical features: 
Digital input: 1 USB 

Digital input: 1 update port, for future digital 
input standards. 

The upgrade port can also be used for the future 
Densen WiFi board, allowing the DenDAC50 to 
receive digital signals by WiFi. 

Digital input: 2 sets digital coax spdif. 

Digital input: 2 toslink optical inputs. On Toslink 
the design do support 24/192, but due to examples of poor hardware in the sources, Densen only guarantee 24/96 performance on Toslink. 

Converter type: 24 bit/192KHz 

Output stage: a non feedback design without 
local or global feedback.

Official Pressrelease – March 2015 
The DenDAC 50 makes extensive use of SMT (surface mount technology), a technology which has seen extensive use in the audioindustry the last 5 years, but which Densen has pioneered since 1994. As good audiodesign is not only about using the right components, but also about the implementation and manufacturing process in order to achieve highest quality level, lifetime, and sound quality. 

As usual for a Densen product, the powersupply is carefully optimized. DenDAC50 contains 2 custommade toroid transformers, each with no less than 4 power outputs, so a total of 8 transformer outlets. They feed 5 rectifier bridges and 50.000 uF of storage capacity. Further, nothing less then 18 individual regulators feeds the delicate circuits, and allow each circuit to perform perfect, without interference from the others. 
the Densen design team has focused totally on creating a DAC that not only sets new standards for the price range, but actually plays music in a way, that allows the listener to really dig into the music. 

The DenDAC50 uses the best components throughout the design, such as custommade capacitors, Vishay metalfilm resistors, goldplated RCA’s with direct connection to the printed circuit board. And high quality film capacitors. 

Soundwise the DenDAC50 is the result of Densen headhoncho Thomas Sillesens desire to make a DAC that will be a benchmark for what can be expected from DACs, not only at the pricepoint of the DenDAC50, but also at pricepoints much higher. The DenDAC50 is transparent, dynamic, precise, engaging, musically correct, with a precise soundstage, and the ability to create a sound so good you forget you are “just” listening to a digital source. 
As with all Densen products the keywords for the DenDAC50 are: Life is too short for boring hi-fi
