Shockingly dynamic and expressive in the midrange/treble, and confident and tight in the bass... AND they still manage to be beguiling and musical! What more do you need from a 300B? After listening to these I don't think I will ever consider anything other that WE replicas or WE originals in the future. Psvane ACME 300B-Lush midrange. Very musical. 300B TJ Premium. This Valve is rather new, the units I tested where some of the first series units. They are being made in China in the Tianjin Province, the supplier being somewhat coy about more details. The Factory specializes in early WE Replicas and has build up quite a reputation in Japan.
