The chassis of the ES model has been fundamentally revised: the overall thickness has been increased for improved rigidity, and the structures of the transformer base and other wei ght-bearing parts have also been redesigned to improve the instantaneous power and crispness of the sound, when compared to a conventional chassis. Designed with an offset screw position to both eliminate the resonance point and avoid frequency-specific, vibration-inducing resonance transmission to and from the transformer, the foot also contains additional ribs for increased rigidity and improved resonance control. Metal ES-grade frames both secure the circuit board and protect it from vibration caused by speaker sound pressure. The varying fin length of the integrated heat sink reduces audible resonance uniformity while also shielding delicate circuitry from noise. Digital PCM signal input is processed at 32-bit and converted to analog by the DAC, while DSD signal input during direct mode is natively input to the DAC and converted to an analog signal. Show more
