{"product_id":"jitterbug","title":"AudioQuest JitterBug USB Noise Filter — Dual-Line Conditioning","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe JitterBug is a passive USB filter that plugs directly into any USB port and addresses two separate problems simultaneously: noise on the power line and noise on the data line. Both are real, both are audible, and both are present in every computer USB output to varying degrees. The dual-line conditioning circuit — no active components, no power required — reduces the RF noise that computer motherboards generate and couple onto the USB bus, which reaches the DAC as jitter artifacts and elevated noise floor.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe argument is simple. USB was designed to transfer data between computers and peripherals, not to serve as a low-noise audio interface. The power and data lines share a conductor environment with every other process running on the motherboard. A USB DAC downstream of a computer is receiving a noisy signal regardless of the DAC's quality. The JitterBug goes between the computer and the DAC — or into a second USB port on the same computer to further reduce system noise — and cleans what the computer is putting on the line before it reaches the converter.\u003c\/p\u003e","brand":"Audioquest","offers":[{"title":"Default Title","offer_id":44432541155465,"sku":"JITTERBUG","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/4557\/0185\/files\/jitterbug.png?v=1779247418","url":"https:\/\/echohifi.com\/products\/jitterbug","provider":"Echo Audio","version":"1.0","type":"link"}
