Quadraspire Q4L Evo HiFi Racks

What you place your HiFi on will affect its performance. Placing your HiFi on a Quadraspire performance HiFi rack will help reduce resonance, lower the noise floor, and open the soundstage to make your HiFi sound even better.

The Q4L Evo is the deeper-shelf sibling of the Q4 Evo — the rack that started Quadraspire in 1995, refined steadily ever since. It carries the same architecture as the standard Q4 Evo: solid bamboo-ply shelves on 32mm (1.26") curved aluminum columns, machined and chamfered to suppress vibration and avoid the parallel surfaces that encourage resonance, with each shelf supporting up to 80kg (176 lb). The Q4L Evo's larger shelf footprint accommodates components that exceed the standard Q4 Evo's shelf depth — long-chassis amplifiers, deep streamers, transports with extended mechanisms. Available in 2-5 shelf configurations.

Solid Bamboo Ply

Some shelf materials, like glass, resonate and can distort the sound of your system. As a result of extensive testing, Quadraspire uses solid bamboo ply that suppresses vibrations and is also carbon neutral. Available bamboo finishes: Natural, Dark, Cherry, and Black.

Solid Aluminum Columns, 32mm (1.26")

Steel tube can resonate and distort sound. Aluminum has much less resonance, so Quadraspire uses it for all columns and feet — solid, not tubular, to dissipate energy quickly. The Q4L Evo's 32mm (1.26") SV columns are available in Black or Matt Silver, in heights of 100mm (3.94"), 140mm (5.51"), 180mm (7.09"), 216mm (8.50"), 256mm (10.08"), and 326mm (12.83").

Larger Shelf Footprint

The defining difference between the Q4L Evo and the standard Q4 Evo is shelf size — the Q4L Evo's deeper shelves accommodate components that exceed the Q4 Evo's shelf depth. The structural architecture is the same; the platform is larger.

Designed to Avoid Parallel Lines

Parallel lines on rectangular shelves encourage resonance which can distort sound. Where possible, Quadraspire avoids parallel lines in the same way as most musical instrument designs.

Footer Options

The Q4L Evo can be specified with spikes, flat feet, or castors, with an optional bronze upgrade for the feet — bronze and brass dissipate vibration in the same way they ring well in musical instruments.

Each rack is built to order. The shelf count is selected at purchase below; the wood finish, column color, footer style, and column height are configured through Quadraspire's Build-and-Price tool, or by speaking with us directly. For standard-depth shelves at the same per-shelf weight rating, see the Q4 Evo. Designed and built in England by Quadraspire, since 1995.
