Why discrete, and why class-A?

In the golden age of audio, all electronic devices were assembled using separate parts, such as resistors, capacitors, and transistors. These individually soldered components create an operational amplifier, a Discrete Operational Amplifier (Op-Amp). As a foundation of our rotaries, we use the discrete op-amps in the Phono inputs, EQs, Summing, Sends/Return, and all the Outputs.

We can design a discrete op-amp with various output stage types, such as Class A. A benefit of a Class A output stage in audio is reducing crossover distortion. In some designs, the signal can get slightly distorted when transitioning between positive and negative voltage swings. Class A keeps the output transistors constantly conducting, minimizing this distortion. It particularly appeals to us, as our in-house-developed discrete op-amp directly addresses this. Besides, we're simply in love with a transparent, undistorted sound.

Sound quality is paramount in audio. However, fitting everything onto a single chip can sometimes affect that. With a discrete circuit, we have more control. It's like building our high-end stereo system from scratch. We can pick each component individually, the best for sound quality, and only use the exact parts needed for the job. That means a simpler circuit, but the one that lets the pure, unadulterated sound of the music shine through.

So, next time you listen to your favorite records, think about the journey the sound takes. It travels through a maze of carefully crafted discrete circuits built with the love of music in mind.
