Bright Star - IsoNodes - Large - Set of Four
Category: Accessories
Polymer Feet in Three Sizes, Rated 30 to 60 Pounds a Set
Bright Star IsoNodes are sold as a set of four in three sizes: Small, Large and Extra Large. Each is a half-dome of Bright Star's own polymer with an adhesive backing. A set carries a component of 30, 42 or 60 pounds, depending on the size.
A component's stock feet pass shelf vibration straight into its chassis. Bright Star forms the IsoNode from a polymer it compounds for this job, not Sorbothane. The component rides on the four domes instead of the shelf.
Pick the Size by the Weight, Then Add Feet if It Is Heavier
Fit, Load and Materials
The Small IsoNode is 3/4 inch across and 3/8 inch tall, rated 30 pounds for a set of four. The Large is 1 1/4 inches across and 5/8 inch tall, rated 42 pounds. The Extra Large is 1 3/4 inches across and 3/4 inch tall, rated 60 pounds.
No minimum is published, but a dome loaded far under its rating never reaches its working range, so match the size to the component rather than simply buying the largest. Bright Star says to add feet to carry a heavier component or to spread an uneven load.
Height added is 3/8 to 3/4 inch, so a low shelf still clears. The adhesive backing holds each foot to the chassis, which matters for a component you slide in and out of a rack. Bright Star states plainly that IsoNodes are not made from Sorbothane.
What Reviewers Are Saying
Stereophile lists the IsoNode feet in its Recommended Components 2025 Edition. Sasha Matson found that “The IsoNodes effectively isolated the Music Hall USB-1 turntable from footfalls” and were stable under his other components.
Mark Wheeler has reviewed the IsoNodes twice for TNT-Audio. Of the Extra Large he wrote: “Of the purely blobby vibration control devices they remain the best I have heard.”
In his earlier review of the standard IsoNodes he was just as direct: “I would strongly recommend the IsoNode anti-vibration feet.”
Who Are the IsoNodes Best For?
- You own a disc player, DAC or streamer under 30 pounds — four Small IsoNodes carry it inside their working range
- You run an integrated or power amp of 30 to 60 pounds — the Large or Extra Large set carries it, and a fifth foot covers a heavy transformer end
- You slide components in and out of a rack — the adhesive backing keeps the feet on the chassis instead of on the shelf
- You want a foot that is not Sorbothane — Bright Star uses its own polymer and says so
- Your component weighs more than 60 pounds — two sets of Extra Large IsoNodes, eight feet, carry 120 pounds with the load spread evenly
How Do You Set Them Up?
Weigh the component and pick the size whose rating covers it. Turn the component over, peel the backing from each foot, and press one onto the underside near each corner, clear of the stock feet. Set the component back on the shelf so it rests on the domes. Check that it sits level and does not rock.
Pairs Well With
What most IsoNode owners shop next.
- Audio racks — a rigid, level shelf gives the pucks a firm grip
- Power conditioners — cleaner power for the gear you are isolating
- Isolation feet and cones — the other rungs for the rest of the rack
- Cables — the natural next upgrade for an isolated source
Frequently Asked Questions
How many do I need?
Four per component, and the set covers one component. Bright Star rates each set for a total weight, so a component heavier than the rating takes a fifth or sixth foot, or a second set.
Which size do I need?
Go by the weight of the component: Small up to 30 pounds a set, Large up to 42, Extra Large up to 60. If the weight sits close to a limit, take the next size up or add a foot.
Are IsoNodes made of Sorbothane?
Bright Star says they are not. The IsoNode is made from a polymer Bright Star compounds for vibration control. It is soft to the touch and slightly tacky, like Sorbothane, but a different material.
Will they stay in place?
The adhesive backing holds each dome to the chassis. Stereophile's Sasha Matson found them stable under most components, though easy to knock out of place under a turntable with pivoted feet.
