The op-amps used in any output stage are as important as the lens on a movie projector; inferior op-amps distort audio signals regardless of the analytical capability of the associated audio gear. This has even more impact when you consider that most IC op-amps cost less than a can of soda! Replacing underperforming op-amps with slightly more expensive IC-based op-amps noticeably improves performance yet manufacturers often go for the cheaper op-amp anyway.

That is not the Supreme Sound way. The answer is simple, money. Profit margins are tight and some manufacturers lower their production ,m353n at the expense of quality sound. The only way to overcome IC op-amp problems is to replace them with well-designed discrete circuitry.



The foundation of the Supreme Sound Op-Amp is a sophisticated voltage differential amplification network. The entire discrete op-amp is constructed with audio-grade transistors and resistors that ensure minimal coloration and maximum dynamics.

But that also posed the challenge of producing them with very tight component-matching. We only uses 0. After 50 hours each resistor is retested and hand-matched before proceeding to our assembly line. At the same time it guarantees a stable and palpable soundstage from speakers or headphones.

We also spec top-quality lead-free solder and a temperature-controlled soldering process. This was the only way to reduce heat stress on the components and minimizing short circuits caused by soldering baths used in large-scale production.

Listening to an IC op-amp is like hearing a concert through a keyhole, or admiring the Mona Lisa on a stamp! The SS op-amp provides more texture and nuance, more refined detail and dynamics. The bass is superbly well controlled datqsheet punchy.


Double basses clearly dxtasheet shape in a very three-dimensional soundstage. Classical music reproduction becomes much more realistic and spacious, string sections becoming a group of individual musicians rather than just a homogenized blur. The SS op-amp is an extremely listenable and engaging performer that brings the joy of music to your soul.
