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.\u003c\/p\u003e\n\n\u003ch5\u003eWhy the Materials Matter\u003c\/h5\u003e\n\u003cp\u003eEach Q4 EVO shelf is solid bamboo ply. Quadraspire tested other shelf materials, found that glass and similar surfaces resonate, and settled on bamboo because it suppresses vibration (it is also carbon neutral).\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/quadraspire-svt-bamboo-ply-shelf-edge-inline.jpg?v=1793283435\" alt=\"Quadraspire solid bamboo ply, shelf edge close-up showing the laminated layers\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003cp\u003eEvery shelf is then machined to cut resonance further, and its edges are chamfered, which Quadraspire says helps dissipate energy.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/quadraspire-q4-evo-chamfered-shelf-edge-inline.jpg?v=1793298736\" alt=\"Quadraspire Q4 EVO natural bamboo shelf corner, close-up of the chamfered edge\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003cp\u003eThe columns and feet are aluminum rather than steel tube. Steel tube can resonate and distort the sound, and aluminum has much less resonance, so Quadraspire uses it for every column and foot.\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 columns\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003cp\u003eThe shelves and columns are curved on purpose: parallel lines on a rectangular shelf encourage resonance, so the Q4 EVO avoids them wherever it can.\u003c\/p\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\n\u003ch5\u003eThe Spacing, Shelf by Shelf\u003c\/h5\u003e\n\u003cp\u003eFrom the floor up, this rack uses columns of 256, 256 and 216 mm, which is 10.1, 10.1 and 8.5 inches. The two lower shelves get the most height, so that is where a power amp or a tube amp goes. The third shelf has 8.5 inches, room for a tall integrated or a small tube amp, and the top shelf has nothing above it, so a turntable lid opens all the way. Overall the rack stands 35.0 inches tall on its spikes.\u003c\/p\u003e\n\u003cp\u003eThe shelf itself is 23.2 x 15.6 inches, with 477 x 297 mm (18.8 x 11.7 in) between the columns. Check the depth of your deepest component against that before you order; if it needs more, the Q4L EVO uses the same parts with a deeper shelf.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/quadraspire-q4-evo-rack-shelf-heights-inline.jpg?v=1793298745\" alt=\"Quadraspire Q4 EVO 4-Shelf HiFi Rack heights diagram, 3.9 in to the bottom shelf, then 10.1, 10.1 and 8.5 in between shelves, 35.0 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-q4-evo-shelf-dimensions-inline.jpg?v=1793298748\" alt=\"Quadraspire Q4 EVO shelf dimensions, 590 x 395 mm top view diagram\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\n\u003ch5\u003eBuild Your Own Q4 EVO\u003c\/h5\u003e\n\u003cp\u003eThis rack is one way to build a Q4 EVO.
