What I find with the WA3 is it amplifies what goes in very well. Poor source and cables is readily reflected in the output, as is almost every recording artifact I've never noticed before. In tracking this one with the I-20, I did discover Woo ties signal ground and chassis/earth ground together in the amp. So, it appears the I-20 with its two prong wart and Woo with 3 prong earth have different references. Interesting. I may need to do some web research and see how other mainstream and high end audio manufacturers reference ground. Sounds like a good reason for balanced inputs and outputs.

It's a strange amp indeed.
