Manufacturer Details

The New FET Input Stage.The input stage of the Soloist is a symmetrical existing feedback circuit with just 21 parts on its signal course (compare that to a typical IC Opamp of over 50). It's signal course is so brief and with so little obstruction on it, that it can accomplish fantastic audio. Likewise because Burson just had to choose and match 21 parts, the Soloist sounds definitely fantastic. Variable Output Stage. The input stage of the Soloist is a symmetrical existing feedback circuit with just 21 parts on its signal course (compare that to a typical IC Opamp of over 50). It's signal course is so brief and with so little obstruction on it, that it can accomplish fantastic audio. Likewise because Burson just had to choose and match 21 parts, the Soloist sounds definitely fantastic. The new Soloist has actually taken the currently fanatical IC totally free power supply of the generation HA-160 to the next level. The outcome is even cleaner even more energetic music recreation. When power leaves the creating station it is pretty clean. Sadly, every device attached to it draws a current which damages the purity of the voltage wave type. Open air high voltage cables can get radio signals from all sort of sources. Transformers throughout the national grid are running near saturation point, which develops more distortion. From big electrical motors such as those utilized in factories, to baby alarm systems and hairdryers, all can pollute to excruciating levels. It does not end there! The power supply from the majority of hi-fi devices are amongst the worst polluters. A huge amount of disturbance is created by the conventional IC voltage regulatory authorities; they inject sound of their own due to the nature of their operation, shutting out musical detail that we work tirelessly to protect. High Resolution Volume Control At the time when an audio signal is passing through the volume control, it is still at its weakest. At this stage, the audio signal is really susceptible to sound pollution and disturbance. A major source of such distortion is the frequently utilized remote volume control adopted by the majority of manufacturers. Burson developed a 24 stepped attenuator specifically for the P-160 series. Unlike frequently readily available stepped attenuators on the Do It Yourself market, ours just includes one < 0.1 % metal movie resistor on the signal course. The outcome is an overall removal of any distortions introduced by the volume control (which can differ approximately 7 % on a conventional pot). The Burson stepped attenuator is developed with exceptional quality parts incorporated with our solid machined aluminium knob. It ensures a smooth and well controlled mechanical motion. The volum e curve was tailor made to match our 160 line providing the user a smooth control over the entire spectrum. The decision to embrace a custom developed step attenuator over a remote volume control was controversial however the outcome was definitely not! Resonance Free Aluminum (RFA) Enclosure. The Soloist is housed in a 6mm case, built from high precision machined aluminum. This enclosure permits the Soloist, to accomplish a really high mechanical damping element, which minimizes any microphonic results that may break down the quality of sonic efficiency. The enclosure was also built to act as a giant heat-sink, which permits the Class-A head-amp to run cooler, and continue to be optimized at all times.Sometimes called"the safe"by Burson clients, the Burson RFA enclosure is built from precision machined aluminium panels. Just 8 stainless-steel bolts were required to sign up with the enclosure, which then ended up being essentially unbreakable.
