Got in on the ACA mini clone board buy and Nelson was a legend as always and provided the Harris output devices. If an amp can be cute, it's this one. Perfect desktop size at roughly 5 inches square. My desktop setup is not for critical listening so this is not a review. I'll just say it sounds wonderful. Perfect project for someone wanting to get into DIY whenever it makes it to the DIY store. Parts cost was ~$200 so I assume that's how much the kit will end up being. Using a WHAMMY as preamp.
