Densen B-350PLUS Power Amplifier

Collections: Densen Amplifiers

Type: Amplifier


The B-350PLUS is Densen's top of the line power amp. The new B-350PLUS contains a completely new output stage, built using Densen’s unique "DMCD" technology (patent pending). This makes the B-350PLUS extremely fast and precise, while retaining unlimited control of the speakers. The bandwidth has also been improved and the B-350PLUS goes to 400.000Hz, resulting in improved slew-rate and an extremely fast and detailed sound.

The B-350PLUS is built using surface mounting teqniques, and the components are mounted to a precision of 0.02mm using silver solder. All solderings are carried out in an artificial nitrogen atmosphere to avoid oxidation of the solderings. The power supply is massive and consists of a 750VA transformer and has a storage capacity of 100.000uF with 4 seperate rectifiers, 2 of which are capable of 3.000VA. Unusually for an amplifier, not all the capacitors are mounted in a capacitor bank, as some are located next to the output stage for faster power delivery. All resistors are laser-trimmed metalfilm from Vishay with a precision of 0.1%. The B-350PLUS delivers 125W at 8 ohm, and 250W in 4 ohm.

No local or global feedback is one of the key issues with the B-350PLUS. This technology is further improved with Densens new patent pending DMCD (Dense Mass Current Distribution) circuit. By using the DMCD circuit, the current is at all times present at the output terminal. This results in an extremely low output impedance and a truely non-feedback amplifier.

The printed circuit board is made of teflon and is doublesided, allowing the signal to be placed on one side and groundplane on the other, thereby optimising interference free signal transfer.

The B-350PLUS contains several exciting features. On the backpanel there is a switch to adjust the gain, so that the B-350PLUS works perfectly with a traditional preamp, as well as a CD-player with variable output.

There is also a D-Sub15 connector, allowing for DenLink connection to other Densen products, such as auto power on/off.

The B-350PLUS is also prepared for Densen’s SAXO electronic crossover, so that the B-350 can be used in active systems. This is done by mounting the crossover in an internal socket. The SAXO crossover is user adjustable and will fit all speakers on the market.

For all at Densen the birth of the B-350 is a significant moment. At Densen the B-350PLUS has for several years been the internal reference, and therefore it is a pleasure to be able to show audiophiles all over the world the true musical world of Densen.
