Welcome to Dolphin Hollow State Labs!

Our specialty is original design audio amplifier kits for the Do It Yourself Community. In case you were wondering, our designs are vacuum tube based, therefore "hollow state", as opposed to solid state. Perhaps you remember vacuum tubes: they glow in the dark and get hot. To this day, no one has yet to develop an active device that is better suited to analog amplification. This is a discovery that increasing numbers of people who appreciate really good sound are making every day.

Good sound need not cost a fortune.
