Improvements over the HA-160D Based on what Burson learned from the Conductor project, they 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. Variable Output Stage (VOS) The Conductor SL features a new Variable Output Stage (VOS). It enables the Conductor to match well with any type of headphone. Be it easy to drive high sensitivity in ear monitors or open back moving-coil designs. It can drive anything including the latest planar magnetic headphones with ease. With the VOS, volume control is always smooth and synergy is always perfect. Low Noise Power Supply An athlete needs clean air to perform at an optimum standard - audio equipment needs clean power to reproduce transparent and natural music. The new Musician Series has taken the already fanatical IC free power supply of our Classic Series to the next level. The result is even cleaner even more energetic music reproduction. The Conductor SL9018 is like a luxury dining experience. Tablecloth crisp, glasses chilled, the cuisine painstakingly prepared and every minute detail ready for examination. Every moment is the result of people (us) pushing the boundaries of possibility. It is a timeout from your life and it deserves your full attention in your best suit.
