You haven’t heard an amplifier until you hear a properly designed and implemented Gaincard amp. This amplifier is designed by the inventor of this design so you know it is going to be good. Engaging, musically satisfying and you will find yourself listening for long hours to your music. This amp will get you very close to the ultimate music listening experience.
Here are some comments by Herb Reichert of Listener magazine which are absolutely true:
Easily the smallest, most solidly built, and most musically effective solid-state amplifier through which I've ever played music.
The 25-watt Gaincard amplifier will outplay the Krells and Levinsons, it will reveal more of the poetry and structure of musical art than any silicon-based amplifier I have experienced.
