The Soloist SL is a concentrated version of the award winning Soloist. Its DNA is identical to the Soloist and it exists for one purpose only. That is to be one of the best headphone amplifiers in the world. Just like the Soloist, the Soloist SL is completely discrete in design. (IC free). It features the same 21 component Field Effect Transistor input stage and the same discrete power supply network which brought popularity to the original. Assembled with the same high end components and operating in pure Class-A, the Soloist SL carries the same sonic signature which has been described as the utmost in organic and transparent. At 14cm * 8cm * 21cm (5.5" x 3.15" x 8.26") it sits elegantly on any desktop. But with 2 Watts per channel into 16ohm, the Soloist SL is one of the most powerful headphone amps in the world. It is capable of driving most if not all headphones to their full potential. Coupled with a 2 level gain switch, it offers infinite flexibility. The Soloist SL 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. The Soloist SL features a new Variable Output Stage (VOS). It enables the Soloist SL 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. Combining the VOS with high quality ALPS Potentiometer, volume control is always smooth and synergy is always perfect. An athlete needs clean air to perform at an optimum standard - audio equipment needs clean power to reproduce transparent and natural music.
