Introducing their flagship integrated amplifier. The 91E is the latest advancement in single-ended sound, energized by its famous predecessor the WE 91A.
At double the power, you’ve never heard the 300B express itself like this before. A new level of performance has been achieved with a completely new approach to SE amplifier design. The 91E’s circuitry intelligently steers the parallel feed constant current source (SCCS), allowing the tubes to deliver more than double their previously rated output of 7-8 watts.
Prices are: £16998 for Black or Gold, £18500 for the nickel (Silver) finish.
