A new amp by David Berning, the Audioism10 is his take on an EL-84 based circuit. The Audioism10 Power Amplifier provides 10 watts per channel output of accurate, uncolored sound with automatically protected circuitry.
These products are based on Berning's patented architecture known as ZOTL, which stands for ZERO Hysteresis Output Transformer-Less.
