Mother Audio WAI 2950

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.

How does it sound?
Completely magical, huge, but still focused low end and incredibly sweet highs, creamy mid range, very characteristic for an inductor based circuit.

What can it be used on?
Anywhere where you actually want character and sweetness.
