LIFES is based on the technical concept of our revolutionary ODNF feedback circuitry, which achieved excellent static characteristics without feeding back any of the musical input signal to the main amplifier, yielding a natural sound quality more akin to a non-feedback system. The circuit has been redesigned from scratch through multiple simulations. By combining carefully selected components and through repeated listening tests, we have achieved the ultimate performance and sound quality, truly worthy of being adopted for LUXMAN’s next-generation components. In LIFES Version 1.0, the entire circuit has been reconstructed and simplified, improving performance, whilst also successfully reducing the number of parallel elements, reducing distortion during amplification to less than half. The output stage uses a parallel push-pull configuration with bipolar transistor elements, achieving ample Class AB power of 100W+100W (8Ω) and 150W+150W (4Ω). \u003cdiv class=\"small\"\u003e*LIFES stands for “Luxman Integrated Feedback Engine System”. *ODNF stands for “Only Distortion Negative Feedback”.\u003c\/div\u003e   \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv class=\"row row-eq-height-detail\"\u003e \u003cdiv class=\"col-md-6 col-sm-6 col-sm-push-6 col-md-push-6 item_img\"\u003e\u003cimg class=\"center-block img-responsive\" src=\"https:\/\/www.luxman.com\/asset\/product\/L-505Z\/pb2.jpg\" alt=\"Electronically controlled attenuator LECUA\"\u003e\u003c\/div\u003e \u003cdiv class=\"col-md-6 col-sm-6 item_detail_1 col-sm-pull-6 col-md-pull-6\"\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ch3\u003eElectronically controlled attenuator LECUA\u003c\/h3\u003e The volume control section is crucial to both the functionality and performance of an integrated amplifier and requires dedicated signal processing. The L-505Z is equipped with LUXMAN’s original, high-clarity LECUA* electronically controlled attenuator, which has been significantly downsized by adopting a solid-state (IC) circuit configuration. LECUA is an ideal level control system that minimizes variations in audio quality and enables smooth and detailed volume adjustment over 88 steps. The LR balance adjustment control also relies on LECUA's volume shift function. Despite multitasking, LECUA succeeds in minimizing deterioration of sound quality across the full range of the volume control. Intuitive operability is maintained while linked with operations from the remote control. A traditional rotary volume knob achieves that weighty, tactile response and operational feel enthusiasts will enjoy, combining convenience with pleasing operability. \u003cdiv class=\"small\"\u003e*LECUA stands for “Luxman Electronically Controlled Ultimate Attenuator”.\u003c\/div\u003e   \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv class=\"row row-eq-height-detail\"\u003e \u003cdiv class=\"col-md-6 col-sm-6 item_img\"\u003e\u003cimg class=\"center-block img-responsive\" src=\"https:\/\/www.luxman.com\/asset\/product\/L-505Z\/pb3.jpg\" alt=\"Discrete buffer circuitry for preamp\"\u003e\u003c\/div\u003e \u003cdiv class=\"col-md-6 col-sm-6 item_detail_2\"\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ch3\u003eDiscrete buffer circuitry for preamp\u003c\/h3\u003e The concept of a “power amp driver” is fundamental to the design of a preamp section, outputting an energy-rich signal is its ideal state of operation. The L-505Z is equipped with discrete buffer circuitry and high current supply capability at the output of the preamplifier stage, maintaining the fidelity of delicate musical signals whilst significantly enhancing the driving energy and performance of the power amplifier stage. The input selector switch controls a switching IC with excellent separation and low crosstalk. Proudly joining our latest Generation Z series, the L-505Z has achieved a dramatic development in musicality that far surpasses its class. In addition, responding to the reestablishment of vinyl record playback as an important contemporary source, a high-quality MM\/MC compatible phono EQ amp circuit with a parallelized first stage is provided to realize supreme analog playback similar to our other high-end components. \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv class=\"row row-eq-height-detail\"\u003e\u003c\/div\u003e","brand":"Luxman","offers":[{"title":"Default Title","offer_id":53953923121489,"sku":null,"price":14449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1047\/7178\/0945\/files\/505z-f.jpg?v=1780580823","url":"https:\/\/gridhifi.com\/products\/luxman-509z-integrated-amplifier","provider":"The Grid","version":"1.0","type":"link"}
