Their argument is simple: what you place your hi-fi on affects how it performs. Quadraspire picks every material and shape to reduce resonance, with the stated goal of lowering the noise floor and opening up the soundstage. The X-Reference is the top tier of their range.\u003c\/p\u003e\n\n\u003ch5\u003eWhy Nextel, Bronze and Aluminum\u003c\/h5\u003e\n\u003cp\u003eThe Signature takes the X-Reference and coats it in Nextel, which Quadraspire uses to make a system sound better and to give the rack a striking finish. Each level is two parts: the columns screw into a Nextel X frame, and the shelf rests on four bronze feet set into that frame. Quadraspire's research found that bronze and brass are good materials for reducing resonance, and it is no coincidence that a lot of musical instruments use them.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/quadraspire-signature-x-reference-black-nextel-close-up-inline.jpg?v=1793298959\" alt=\"Quadraspire Signature X-Reference black Nextel shelf on a bronze foot above the black Nextel X frame, natural aluminum column, close-up\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003cp\u003eThe X frame is Nextel coated and built to be light while keeping its strength: one X shelf weighs 2.2 kg and holds over 80 kg.\u003c\/p\u003e\n\u003cp\u003eThe 44 mm columns and the feet are natural aluminum, because steel tube can resonate and aluminum has much less resonance. The feet finish in bronze spikes.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/quadraspire-svt-solid-aluminum-bar-stock-inline.jpg?v=1793283440\" alt=\"Quadraspire solid aluminum bar stock used to machine the Signature X-Reference columns\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/quadraspire-sv-tapered-columns-inline.jpg?v=1793283432\" alt=\"Quadraspire aluminum columns in five heights, side view\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003cp\u003eThe frames, shelves and columns are curved on purpose: parallel lines encourage resonance, so the Signature avoids them wherever it can.\u003c\/p\u003e\n\n\u003ch5\u003eThe Spacing, Shelf by Shelf\u003c\/h5\u003e\n\u003cp\u003eFrom the floor up, this rack uses columns of 250, 250 and 200 mm. Each shelf rides on bronze feet above its X frame, so the clear space over a shelf is 70 mm less than the column: 7.1 inches (180 mm) above the bottom two shelves and 5.1 inches (130 mm) above the third. The two lower shelves take the heavier pieces, an integrated or a power amp, and the third suits a streamer, DAC or phono stage. The top shelf has nothing above it, so a turntable lid opens all the way. The bottom shelf sits 6.3 inches off the floor, and the rack is 36.3 inches tall to the top shelf.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/quadraspire-x-reference-rack-shelf-heights-inline.jpg?v=1793298961\" alt=\"Quadraspire Signature X-Reference 4-Shelf HiFi Rack heights diagram, 6.3 in to the bottom shelf, then 7.1, 7.1 and 5.1 in of clear space on 250, 250 and 200 mm columns, 36.3 in overall\" style=\"display:block;width:100%;max-width:600px;height:auto;border-radius:12px;margin:16px auto;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/quadraspire-x-reference-shelf-dimensions-inline.jpg?v=1793298964\" alt=\"Quadraspire Signature X-Reference shelf dimensions, 590 x 470 mm shelf on a 720 x 590 mm X frame, top view diagram\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\n\u003ch5\u003eBuild Your Own Signature X-Reference\u003c\/h5\u003e\n\u003cp\u003eThis rack is one way to build a Signature X-Reference.
