The B-320PLUS is the successor to the critically acclaimed B-320 and is built directly on the B-320. The B-320 was the most sold Densen power amp ever. Now it has been tweaked and fine tuned to deliver an even more impressive performance. The B-320 contains an output stage built using Densen's unique DMCD technology. This makes the B-320PLUS extremely fast and precise, while retaining

unlimited control of the speakers that are connected. The bandwidth is also extreme and goes to 400.000Hz, resulting in improved slew-rate. This amplifier has - like any Densen amplifier - the capability to drive any loudspeaker on the market. The sound is fast, transparent and dynamic while still having the refinement of a true musical performer.

The B-320PLUS is built using surface mounting techniques and the components are mounted to a precision of 0.02mm using silver solder. All solderings are made in an artificial nitrogen athmosphere to avoid oxidation of the solderings. The power supply is massive and consists of a 800VA transformer, with a storage capacity of 100.000uF with 4 separate rectifiers, of which the 2 are capable of 3.000VA. Unusually for an amplifier, the capacitors are not all mounted in a capacitor bank; some are located next to the output stage for faster power delivery. All resistors are laser-trimmed Vishay metalfilm with a precision of 0.1%. As a special feature, the emitter resistors consist of twelve 0.1% metalfilm resistors in parallel (per output transistor = 96 resistors in total), ensuring no induction and, at the same time, a large surface for passing the substantial audio signals to the output terminals. Since they are in parallel, they actually have a much improved sonic signature compared to the conventional solution with a single resistor. The B-320PLUS delivers 2x100W at 8 ohm, and 2x200W in 4 ohm. The mains transformer is wound in a special way to lower the noise floor and actively function as a shielding transformer.

By using a new power supply set-up, the B-320PLUS also has an extremely dark background, which makes the amplifier sound extremely controlled, but still provides lots of emotion and spark.


No local or global feedback is one of the key issues with all Densen designs, including the B-320PLUS. This technology is now further improved with Densens new patent pending DMCD circuit. DMCD stands for Dense Mass Current Distribution, and 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 circuitry is manufactured as single ended all the way from the input terminal to the output stage.

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

The B-320PLUS contains several exciting features. On the backpanel there is an external switch to adjust the gain, so that the B-320 works perfectly with a traditional preamp, as well as with 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 from a Densen preamp or integrated amp.

The output terminals are doubled for easy bi-wiring.

The B-320PLUS is also prepared for Densen′s SAXO electronic crossover, so that the B-320 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.

The B-320PLUS controls even extremely large speakers with ease, and it will definitely lead to a lot of people falling in love with music for the first time….and a lot of people falling in love with music for ever…

Tip Echipament Putere Stereo
Pentru Boxe:

- Pentru performante optime este necesara pozitionarea boxelor la o distanta de minim 30-40cm de peretele din spate pentru boxele cu bass-reflex in spate, pentru cele cu bass-reflex in fata, recomandam pozitionarea la o distanta de 10-20cm fata de peretele din spate.

- Boxele vor ajunge sa functioneze in parametrii recomandati de producator, dupa minim 50 de ore (ideal 100 ore) de functionare la volum mediu. In aceasta perioada de timp, de “rodaj a boxelor”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce boxele vor functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate. Exista boxe care necesita un „rodaj” mai amplu de minim 300 de ore mai ales in cazul celor care au difuzoare de kevlar, carbon sau alte materiale de acest tip. Boxele care se „rodeaza” cel mai repede sunt cele care au difuzoare de celuloza.

Pentru Amplificatoare, DAC-uri, Preamplificatoare, Receiver Stereo & Home Cinema, Surse digitale audio-video:

- Pentru performante optime este necesar „rodarea” echipamentului, In functie de complexitatea componentelor din aparatul dumneavoastra acesta poate dura intre 30-200 ore.

- Rodajul se face la volum minim, fiind astfel suficient faptul ca acesta este alimentat corect conform manualului de utilizare la 220-230 Volti si trece semnal audio sau video dupa caz prin el.

- Echipamentul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce echipamentul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.

Pentru cabluri:

- Pentru performante optime este necesara „rodarea” cablurilor, In functie de complexitatea conductorului folosit, cat si geometriei acestuia, „rodajul” poate dura intre 30-100 ore.

- Rodajul se face la volum minim, fiind astfel suficient faptul ca va trece semnal audio sau video dupa caz prin el.

- Cablul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, pe masura ce cablul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.

Pentru detalii privind aceste aspecte de rodaj si nu numai, va rugam sa ne consultati!
