Superb DAC/headphone amp uses the infamous PCM1793 chipset

The HA-160D has been a benchmark in the industry for over 4 years. It is so for two reasons. Firstly, it proved to the world that a properly designed all in one machine can perform at the highest level. Secondly and with no less significance, it smashed the common propaganda that the performance of a DAC is purely dependent on the DAC chip. The HA-160D proved that with a tailored analogue network and power supply network, even a seemingly ordinary DAC chip such as the PCM1793 sounds far more superior than higher spec DACs.

We have now created the Conductor SL (1793) because we know that the PCM1793 chip still has more potential to realize and that the HA-160D can still be beefed up to challenge today's best.

Based on what we have learnt from the Conductor project, we have developed a new FET input stage specifically for the PCM1793 DAC chip. It has significantly less components on the signal path. This resulted in an even more transparent sound.

The driving power of its headphone amplifier has been increased from its original 0.25 Watts pc (@8ohm) to over 2 Watts pc. With such power, the Conductor SL can drive most if not all headphones to their full potential. Coupled with a 2 level gain switch, it offers infinite flexibility.

The Conductor SL (1793) is housed in a refined and precision folded 3 mm aluminium casing that is unmistakably Burson. This case also works as a singular heat-sink for the entire machine ensuring stable and optimized performance at all times. This case really puts the conventional 1 mm folded steel case and generic heat fins to shame.
