WAI (wire and iron) 2950, is a 3 band, completely discrete class A inductor based ,500
series eq. In a way, we recreated the legendary w295, an eq famous for its magically
beautiful “high shelf” and real vintage vibe, the secret weapon of many producers over
the past decades. Input and output are balanced by our custom high class transformers,.
A special challenge was the output transformer, which, with the integrated LPF at 20khz
is a really critical element to not lose the well-known sonic character, and the choice
ultimately fell on the 50%Nickl core. Also, the impedance of the input transformer, (which
in the genuine unit was relatively low) was increased to today's standards and all this
resulted in an extended low freq response and a slightly “excited” sound, if we compare it
with the Siemens module. The pcb board is full of NOS bsx46 Phillips transistors, and as
much as possible Siemens NOS film capacitors.
