SE-300B-Super : 8W x 2 single-ended power amplifier with balanced input

This is one of our state-of-the-art single-ended power amplifiers, using the most common 300B medium power tube as the output section. A high grade silicon-steel 15W single-ended output transformer is used to ensure the highest sonic quality. This amplifier can drive speakers with efficiency above 85db/W, or it can used as the second amp to drive the tweeter section of a bi-wired speaker system.

The XLR balanced input in this unit can further enhance the depth and width of the sound stage by 20-30%, with additional air and solidity in the bass control. Definitely an up-grade from the RCA input version.

A 4ohm or 8-16 ohm selectable output switch is featured for correct impedance matching to almost any speaker. 16ohm speakers can also use the 8 ohm output setting for increased performance.

The 300B has a very sweet and transparent characteristic which makes it very suitable for classical music, vocal, and jazz reproduction.
