Densen now launches the B-175 Integrated Amplifier.
The calibration is done indb steps, allowing a high resolution,.
This means that the microprocessor that also takes care of the B-175s display, remote, inputselector and DenLink multiroom system, also takes care of the calibration of the attenuator to the listening level desired by the listener.
Further the attenuator is calibrated by the user, by an interface with the amplifiers microprocessor.
This attenuator is implemented with the use of Vishay 0,1% lasertrimmed metal film resistors, giving a transparency and accuracy that is outstanding.
Densen has therefore never used digital volumecontrols on any their products, instead opting for an advanced ultra precise attenuator.
On top of that, digital volumecontrols typically has poor performance at low attenuation levels, which is where they are often used in normal listening conditions, where they will have high distortion and time related distortions, resulting in listening fatigue and lack of transparency and details.
However digital volume controls, typically contains over 500 components in a compact microchip, with all the complications this means to the tiny vulnerable audiosignals.
In these times, digital volume controls are often used in even high end amps.
As such it is a pure class A preamp, with an advanced microprocessor controlled attenuator.
This cable was first used in Densens DM-10 amplifier, and now sees its rebirth in the B-175, securing a unsurpassed signal transfer.
The preamp is based on the Densen reference preamp; the B-250.
The poweroutput is transferred internally from the poweramp to the speakerterminals using a custommade cable, which is silvercoated copper with an isolation of Teflon.
The actually poweramp design of the B-175 relies on the B-350 monoblock design, but with a few adjustments, to optimise it for its working conditions in the B-175.
The B-175 contains no less than 10 separate voltage regulators, many implemented as SMD voltage regulators, placed close to where the power is needed, thereby securing a smoth power delivery, to each critical stage of the amplifier.
As such they are tailormade to the way Densen designs amplifiers, to give a performance not even found in the most well respected audiophile capacitors offered by other capacitor manufacturers.
These film capacitors are the result of a long research of the behaviour of capacitors in critical paths of amplifiers.
Further to that, for the first time ever in a Densen amplifier, there is used Densens own filmcapacitors.
No less than 15 custommade capacitors is used in the powersupply of the B-175.
As always with Densen, it contains custommade capacitors made especially for the circuit in which they are used.
The powersupply is made with a toroid transformer, encapsulated for isolation of vibrations to the main PCB, and with separate outputs to all critical stages of the power and preamp sections of the B-175.
The large recessed heat sinks, allows for the amplifier to run with a high bias, thereby securing that most power in normal listening conditions are delivered in Class A.
The B-175 delivers 2x125w in 8 ohm, and 2x250w in 4 ohm, and does this with an ease and control, that must be heard to be believed.
The performance of the B-175 is therefore outstanding, and belies its modest price.
However as always with Densen, the choices have been taken purely on sonic ground.
Naturally some corners have been cut, to shoehorn such advanced products into the cabinet and budget of the B-175.
This is no coincidence, as the B-175 merges the technology of Densens 2 current top of the line products; the B-250 preamp and B-350 mono blocks in one cabinet.
It has the fascia of the B-250 preamp, and combines this with the brute and forceful cabinet of the B-350 mono block with its recessed heat sinks.
From the first look on the B-175 it is obvious that the B-175 is something special in the Densen family.
The B-175 is the most powerful integrated amplifier ever from Densen, but despite that contains a care for details and nuances that is stunning.
