The B-110 is the successor to the B-100, which became the most sold high-end amplifier ever from a Scandinavian audio manufacturer. However, the B-110 takes a giant step forward in terms of musicality. The reviews have confirmed the quality of the “old” B-100 by awarding the B-100 a string of very favorable reviews: “You just can’t beat it”, “rhythmic magic” and “build quality that should embarrass everyone fighting in this price category” – words that tell you it is time to open your ears and listen! The new B-110 will exceed this in every respect! This completely new design is simply sonically superior, because of the high-end details it inherits from its close relation to the B-130 and B-150. The all new B-110 is a true High-End killer!
The volume is controlled by an extremely precise attenuator made of Vishay metal film resistors, which is switched by relays controlled by the microprocessor. Compared to a normal volume potentiometer of the kind used in the majority of all preamps, the resistor network 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 (0.5 dB) even when the sound is so low that an ordinary volume control would create an uneven balance between left and right.
The B-110 output stage utilizes Densen’s unique ”DMCD” (Densen Mass Current Distribution) technology. The B-110 is, as with all other Densen amplifiers, a true non-feedback construction (no global or local feedback), The DMCD technology also secures an extremely firm grip on the speakers combined with a fast, precise and truly transparent sound. As the B-110 is a wide bandwidth design it goes straight to 400.000Hz, resulting in improved slew-rate.
The B-110 is built using surface mounting techniques, and the components are mounted with a precision of 0.02mm (!) using silver solder. All solderings are made in an artificial atmosphere, consisting of nitrogen, to avoid oxidation of the solderings. The power supply is massive, consisting of a 360VA transformer and having a storage capacity of 70.000uF. Unusually for an amplifier, not all of the capacitors are mounted in a capacitor bank, as some of them are located directly adjoining the output stage for faster power delivery. All resistors are laser trimmed metal film from Vishay with a precision of 0.1%. The B-110 delivers 60W in 8 ohm and 120W in 4 ohm.
The transformer is custom-made for the B-110, and is winded using a new technique. This technique reduces vibration from the transformer and therefore reduces mechanical noise from the cabinet. At the same time, this prevents mechanical vibrations from reaching the delicate audio signals on the PCB. It also works as an isolation transformer, thereby eliminating the need to use separate power conditioners.
The special winding techniques used also ensure that the transformer modulates less than is normal (for other amplifiers) during the delivery of large amounts of current. Transformers normally lower the voltage during the delivery of large amounts of current which results in compression of the signal’s dynamics. As a result of the new winding method the transformer in the B-110 is extremely stiff, which means that the voltage does not drop under large current deliveries.
The printed circuit board is made of Teflon, and is double sided to allow for the signal on one side and the ground plane on the other, thereby optimising interference free signal transfer.
The B-110 contains sockets for the SB Board for surround, DP-03 and DP-06 MM and MC stages. There is also the possibility of upgrading the B-110 with the DNRG external power supply to further enhance the sound quality, so as to experience truly breathtaking musical experiences.
