Demidoff Silver Bluenote Demidoff Silver

The Silver uses the finest version of the Bluenote proprietary mirror-amp™ pre-amp section which consists of a gain stage made with a special cascade differential amplifier employing a mirror current. It also deploys a different output design than the other Demidoffs, providing state of the art linearity and imporved efficiency. All of its strategic power and audio sections are wired with rounded solid silver bars. The RSS is a 2mm diameter bar made with 92.5% pure silver and 7.5% electrolytic OFC. It provides the very best "passive" conductivity available. The input wires are connected to the customised selector with a Bluenote 2.5mm silver cable specifically made for this flagship amplifier The power supply is managed by 12 massive custom-designed transformers. in order to ensure the best sonic performance, there is also a smaller transformer electrically isolated from the other ones that is dedicated to powering two separate circuit boards controlling the vu-meter`s fluorescent lights, the motor of the volume control, the internal protection relays and even the power ON LED light.
