| While most of cd players of the same quality are built on tray loader mechanisms or computer cd-rom drives, eGo phase 4 features a true "top loading" concept. To achieve this performance, the designers have installed a renowned read out system from Philips on a 4 mm thick aluminum platform. As with the finest analogue turntables, this assembling is mounted on a sub-chassis thanks to a three-point-suspension. The whole mechanism is superbly finished with a special coating improving attenuation of resonances.Of course, electronics meets very high level requirements too. The digital-analog section is built on a 24 bit / 96KHz converter designed by Burr Brown.The Delta Sigma modulator is based on a 5-level amplitude quantizer and a 3rd-order noise shaper. This advanced topology has the advantage of stability and clock jitter over the typical one-bit solution. With an internal 8x interpolating filter, measurements and sonic performances are unusual at this point. The analog section includes a low-phase-shift filter and the output amplifier. As a natural transcription of sound needs a perfect control of the harmonic spectrum of the signal, a topology using JFETs and bipolar transistors operating in Class A is preferred. Energy is provided by an oversized toroidal transformer. In order to avoid interference between each section, the power supply includes several series-regulators with independent filtering cells. Thanks to the famous "One Touch Control" concept, eGo phase 4 features an attractive timeless ergonomic design. Finally, with a sound which could be almost qualified as "analog sound", eGo phase 4 offers an exceptional ratio performance / price. eGo phase 4 is dedicated to music lovers who are looking for high grade compact solution. |
