Bryston BP-19

Not British Petroleum – Instead, the BP-19 is Bryston's new preamp, "an ultra-high-performance design based on the BR-20. The signal path is fully balanced from input to output, using an array of very tightly matched parts and a compact circuit architecture. This design achieves the lowest possible noise and superior common mode rejection. The BP-19 is meticulously handcrafted in Canada and comes with Bryston’s legendary 20-year warranty." That's all the press release had.
