Sparkos Labs SS3602 Dual

Discrete Operational Amplifier

Built in the USA, the SS3602 discrete stereo op amp from Sparkos Labs is the ideal upgrade for the amplifier stages of a wide range of audio equipment. Unlike the IC amplification chips often used, the Sparkos SS3602 delivers a much more realistic and detailed sound. The discrete OP amp in dual design offers much more power and a much more accurate musical image than would ever be possible with an IC processor. The Class A bias voltage and high output current capacitance, combined with a proprietary compensation system that requires multiple NPO dielectric capacitors, make it impossible to produce these discrete amplifiers as monolithic integrated circuits.

Sparkos OP amps are used by renowned high-end audio manufacturers, in the audio DIY community or for upgrades of existing audio components. Especially the small design with excellent audio characteristics of the Sparkos SS3602 allow impressive results in many different audio applications.

For example, the Sparkos Labs SS3602 Dual Op Amp is often used as an upgrade in the Aune X8 XVIII Magical DAC.

Be careful when installing the Sparkos SS3602 Dual in the Aune X8: Due to the height of the Sparko, the bottom cover cannot be closed anymore and the X8 has to be "raised" as the ground clearance is not sufficient with the original feet.


Sparkos designs its op amps to be as sonically transparent as possible. This means that the opamp amplifies the input signal and produces an exact, larger copy at the output without colouring the sound or creating distortion products (THD).
