Our claim was high, with the Westend Audio Systems LEO we wanted to develop no more and no less than the best 300B-SE integrated amplifier of the modern era. We are proud of our new product and believe: It succeeded! And "best" by no means refers only to the revolutionary tube circuit and the superior sound, but also to the housing and the equipment.

The LEO is manufactured by its developer Günther Mania himself. The resonance-optimized housing is supplied by WESTEND AUDIO. As with the MONACO, it consists of milled aluminum parts whose surface allows many finishes: anodized, chrome-plated, gold-plated… And the equipment is also as you would expect from a modern amplifier, including a sophisticated Bluetooth and an excellent phono board.

But, at the heart of it are of course the two 300B power tubes that run in single-ended Class A operation in the LEO. Unusual is not only that the two 300B are installed horizontally (and so the usual old-fashioned tube amplifier look can be avoided), but a revolutionary circuit that comes instead of the usual 7-8 watts of a 300B smoothly to more than double, and that with at least the same tube life! Because we know: Outputs of 7-8 watts are usually not enough to enjoy music without fear of clipping. But with 20 tube watts many loudspeakers can be operated perfectly. In short the LEO is our interpretation of the modern 300B tube amplifier.
