TopAmp

The TopAmp™ is a specialist audio operational amplifier that uses pure class-A circuitry from input to output, designed to re-capture the clarity and character of classic audio recordings from the 1960’s and 1970’s.

Derived from a long-held understanding that where sonic fidelity is concerned, “less is more”, the TopAmp uses the minimum of components necessary to achieve the performance expected from a modern op-amp in terms of noise, distortion and power supply rejection. 

The discrete TopAmp is the finest op-amp available for audio applications, providing superior sound quality.

The TopAmp is sold as replacement part for Interphase Audio products.
We do not advise on their use in your own circuits, and can not provide support on your designs.
