When the PS1XE is connected, the power supplies for the D\/A converter and buffer amplifier sections are separated, with two independent transformers dedicated to each channel.\u003cbr\u003eThis enhanced power supply architecture minimizes mutual interference between circuit sections while providing an abundant and stable supply of DC power.

This construction minimizes both mechanical and electrical interference between components.\u003cbr\u003eThe high-rigidity enclosure is constructed from thick, heavyweight aluminum panels that effectively suppress micro-vibrations that could adversely affect sound quality.

Suspended from the lower chassis, the top of the foot connects to the lower chassis under the weight of the unit when placed. The top of the foot has been tapered to a conical shape to minimize the contact area between the chassis and the foot. The bottom of the foot (integral spike pad) is also concave in a ring shape so that it touches the floor only at the edges, with added slots to disperse resonant modes. By minimizing the contact area between the chassis and the foot, as well as between the spike pad and the floor, vibration control has been optimized, resulting in sharper focus and a more open sound.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-md-10 col-md-offset-1\"\u003e\u003cimg alt=\"Grandioso PS1XE\" class=\"img-responsive\" src=\"https:\/\/www.esoteric.jp\/images\/products\/_esoteric\/k1xe\/pinpoint_foot_animation_v2hr_en.gif\" width=\"100%\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-md-10 col-md-offset-1\"\u003e\n\u003cdiv class=\"block-title\"\u003e\n\u003cstrong\u003eHigh-Quality Heavy-Gauge DC Cables\u003c\/strong\u003e\u003chr class=\"hr1\"\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"block-detail\"\u003e\n\u003cp\u003eThe Grandioso PS1XE features independent left and right DC power outputs and is supplied with a pair of heavy-gauge DC power cables (1.0 m × 2).
