Densen B-230 Förstärkare
From the first look on the B-175 it is obvious that the B-175 is something special in the Densen family. 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. 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. Naturally some corners have been cut, to shoehorn such advanced products into the cabinet and budget of the B-175. However as always with Densen, the choices have been taken purely on sonic ground. The performance of the B-175 is therefore outstanding, and belies its modest price. 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 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 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. As always with Densen, it contains custommade capacitors made especially for the circuit in which they are used. No less than 15 custommade capacitors is used in the powersupply of the B-175. Further to that, for the first time ever in a Densen amplifier, there is used Densens own filmcapacitors. These film capacitors are the result of a long research of the behaviour of capacitors in critical paths of amplifiers. 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. 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. 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 poweroutput is transferred internally from the poweramp to the speakerterminals using a custommade cable, which is silvercoated copper with an isolation of Teflon. This cable was first used in Densens DM-10 amplifier, and now sees its rebirth in the B-175, securing a unsurpassed signal transfer.
