{"product_id":"lxm-c900u-g91100057","title":"Luxman C900U Control Amplifier","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe C-900U is Luxman's reference preamplifier and the intended partner for the M-900U — two pieces that Luxman designed together and that reviewers have consistently evaluated together for good reason. The volume control is Luxman's LECUA 1000, an 88-step resistor ladder attenuator that replaces the conventional potentiometer entirely. Every step is a fixed resistance value, not a swept contact — which means channel tracking is exact at every listening level, not just at the middle of the range where conventional pots tend to perform best. The balanced amplification circuit handles the hot and cold components of both channels in four independent modules, keeping left and right — and the two legs of the balanced signal — genuinely isolated through the circuit rather than just at the connectors. ODNF 4.0 applies negative feedback only to distortion products, not to the full signal. The power supply draws from a toroidal transformer with capacity equivalent to Luxman's B-1000f monaural power amplifier — a power supply this size in a preamplifier is a statement about what Luxman thinks the rest of the circuit deserves to work with. Tone controls are included, implemented properly, and worth using if the room calls for it.\u003c\/p\u003e\n\u003ch5\u003e\n\u003cbr\u003e\u003cspan style=\"color: rgb(253, 183, 22);\"\u003e$19,900 MSRP\u003c\/span\u003e\n\u003c\/h5\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 255, 255);\"\u003e\u003cb\u003e\u003ci\u003eDue to size and weight, this item may incur an additional shipping surcharge and is listed as Store Pick Up Only.
