The B-330PLUS is a direct descendent from the top of the line B-350 mono blocks.
The B-350 mono blocks act as the internal reference at Densen.
Basically, the B-330PLUS is a stereo power amp based on the B-350's technology, and uses the distinct mono block cabinet with its recessed heatsinks as the basis for an extremely affordable reference power amplifier.
The B-330PLUS contains several exciting features. Externally on the back panel there is a switch to adjust the gain, so it either works perfect with a traditional preamp or with a CD with variable output.
There is also a D-Sub15 connector, allowing for Link connection to other Densen products, and for auto power on/off.
The D-Sub connector can be daisy-chained in multi-room systems.
B-330PLUS is also prepared for the SAXO electronic crossover. This is done by mounting the crossover internally in the B-330PLUS in a socket. The SAXO crossover will fit all passive speakers on the market.
