In the 70's we had an old tube radio with built-in record player that sounded very musical. Then came transistor and MOSFET amplifiers, they were technically better than our old tube radio but did not sound as musical.
Even with an analog record player the amplifier can make or break the sound. Tube amplifiers are still used today for their superior sound but they have their issues. Tubes must be matched and have to be replaced over time. Output transformers in tube amplifiers are never ideal but do have great impact on sound.
We wanted to improve the tube amplifier without losing the sound. Over the years we made many transistor/MOSFET amplifier prototypes and products but never really got the musical sound of our old tube radio back.
In 2016 we also developed a new minimalistic single ended MOSFET amplifier that still has the tube sound but with improved accuracy and control.
We used the same concept of our Cube SE amplifier for our headphone buffer in our Mosaic UV.
