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 techniques, and the components are mounted to a precision of 0.02mm using silver solder. All soldering are carried out in an artificial nitrogen atmosphere to avoid oxidation of the soldering. 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.
Unusual 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 metal film 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 Densen's 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.
