"Even more impressive was the mid-bass response. IT IS AS ADVERTISED! Mid-bass was strong yet detailed, tuneful, and not bloated. This eliminated the mid-bass leanness that can occur at times in my system.
I can honestly say that the HCA-1 is the best amplifier I have heard for its modest asking price"
