The LA6 TX is a simple low gain pre-amplifier that is transformer based and uses the unique WE 205 valve where the emphasis is very much on the sound quality using transformers. It is manufactured for the very finest systems where listening quality is the foundation.
Free from the ‘mechanical’ sound of solid state and the deficiencies of output capacitors, the transformer facilitates reproduction that is more vibrant and focused. The LA6 TX uses four very special line level balanced input and output transformers, developed and manufactured over several years to offer the finest sound.
It uses four very special line level balanced input and output transformers, developed and manufactured in our laboratory over several years to give what we believe to be the finest sound, Two are used for input and two for output. Enabling a true balanced signal path if required. This circuit also works equally well with single ended signals.
At the heart of the LA6tx is the WE designed 205D made by our colleagues at Psvane. Dating back to the early 1930s. His venerable design has a unique “open frame” design and a sound quality which is like no other. The LA6 TX is designed for the very best transistor and valve power amplifiers where musical purity is required over bluntness.
