phase 3

This integrated amplifier from Densen is perhaps one of the most advanced integrated amp on the market. It is filled with advanced solutions, which all share the goal of giving you even more musicality and flexibility. 



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!



The B-150 output stage utilizes Densen's unique "DMCD" (Densen Mass Current Distribution) technology. The B-150 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.



The B-150 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 750VA transformer and having a storage capacity of 130.000uF with 4 separate rectifiers, two of which are capable of 3.000VA. 



The transformer is custom-made for the B-150, and is wound 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.


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-150 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-150 with the DNRG external power supply to further enhance the sound quality, so as to experience truly breathtaking musical experiences.

The DenLink system implemented in all Densen products allows 2-way communication in multi-room installations.
