The B-330 is a direct descendent from the top of the line B-350 monoblocks.   The B-350 monoblocks act as the internal reference at Densen.Basically, the B-330 is a stereo power amp based on the B-350's technology, and uses the distinct monoblock cabinet with its recessed heatsinks as the basis for an extremely affordable reference power amplifier.The B-330 contains several exciting features. Externally on the backpanel 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 multiroom systems.B-330 is also prepared for the SAXO electronic crossover. This is done by mounting the crossover internally in the B-330 in a socket. The SAXO crossover will fit all passive speakers on the market.
