Woo Audio WA7d 'Fireflies' Headphone Amplifier (with DAC) Great tube headphone amplifier in excellent condition with original box. Has a built in DAC and can connect via USB, optical, and RCA. Has connections for 6.35mm and 3.5mm with high and low gain settings available. I can post in the original box at buyers cost thank you. Condition: Excellent Payment Method: PayPal, EFT, Cash on Pickup Region/State: (TAS) Tasmania/Australia By Boney 0 Comments Secure Ad AUD $630 Date: February 22Feb 22
Excellent deal: A$630 for an excellent-condition WA7d sits well below the A$1,052 25th percentile and miles under the A$1,197 median of your recent AUD comps, so this is priced like a bargain rather than a merely fair buy. Against that spread, there’s enough cushion here to feel comfortable even if the listing needs a small refresh or a couple of extras.
The appeal is straightforward: the WA7d is a compact, well-liked tube/hybrid-style desktop amp-DAC that has a loyal following for its engaging, slightly lush presentation and easy, high-end-feeling daily use. In clean condition, with the DAC included, it’s the kind of piece that gives you serious “quality per dollar” at this level, and the price leaves room for any future service or tube-related tinkering without killing the value.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Woo Audio is a New York-based high-end audio company founded in the mid-2000s, with 2006 widely cited as its launch year. It was built by the Wu family, with Jack Wu as the public face of the brand and key design influence, alongside family members who helped shape the company’s early growth. Its roots are in tube electronics and a strong appreciation for live sound, which has remained central to its identity.
The brand is best known for vacuum-tube headphone amplifiers, especially models such as the WA series, along with electrostatic headphone amplifiers like the WES. Woo also makes a smaller range of speaker amps, plus related audio accessories and cables, while its website and retail focus remain centered on amplification and headphone-oriented listening rather than source components or turntables.
In the market, Woo Audio sits firmly in the boutique high-end niche. It is respected among headphone enthusiasts for handcrafted, valve-based designs, substantial build quality, and a distinctive sonic character often associated with warmth, scale, and refinement. It is not a mass-market brand; instead, it appeals to serious buyers looking for premium, specialized amplification with a strong American-made identity.
