Warm Audio manage to deliver the same high-end experience to you, at a much lower price, whilst maintaining all of the top-end detail and low-end presence you'd look for in a quality piece of analog hardware. Maintaining the original basic two-knob control system, operation couldn't be simpler and the results couldn't be better.

Analog Tone

The WA-2A is no exception, providing you with the exceptional warmth and softness of classic '2A style compression in a modern package.
