Debuting as a cohesive partner to the acclaimed MU2 playback system, this Class AB monoblock operates with absolute transparency, utilizing an ultra-dense matrix of ninety-six power transistors on a specialized aluminum substrate to achieve flawless thermal stability. By discarding coupling capacitors entirely and maintaining a remarkably linear loop gain across an ultra-wide bandwidth, the PA1 delivers a level of phase accuracy and spatial resolution that feels less like electronic reproduction and more like an unhindered conduit to the original performance.\u003cspan\u003e\u003c\/span\u003e\u003c!--TgQPHd|||[]--\u003e\n\u003c\/h2\u003e\n\u003cdiv class=\"yhAwj\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-complete=\"true\" data-processed=\"true\" data-sfc-inited=\"2\"\u003e\u003c!--TgQPHd|||[]--\u003e\u003c\/div\u003e\n\u003cdiv class=\"AHmQrc\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-hveid=\"CAAIBxAA\" data-processed=\"true\" data-complete=\"true\"\u003e\n\u003cdiv class=\"n6owBd awi2gc\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-hveid=\"CAAIBxAB\" data-processed=\"true\" data-complete=\"true\" aria-owns=\"action-menu-parent-container\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eThe PA1 mono-block sets a new standard on class AB power amplifier design.
