I have powered it up from 0 battery to full less than 10 times, so it has been very lightly used and the battery and tubes have very low hours on them. After it the battery was fully recharged, I removed it from power. I ship the lower 48 US states only. Dont hesitate to reach out with any questions. Thanks for looking!

Gently used WA2 Ive owned for about 4 years. Functionally in perfect condidtion and looks great cosmetically. These have gone up in price over the years so this is a great deal. The only flaw with this system is that after being on for a few hours the blue LED power light may start to flicker.

First generation Woo Audio Fireflies WA7, used. I bought this directly from Woo Audio owner when I lived in Brooklyn in 2020 and has been used only by myself. Tubes work flawlessly. The transparent glass block on the top has no chips of breaks, only superficial fingerprint smudges. Used this headphone amp for a couple years until I ended up getting an amplifier with a built-in headphone amp, now I no longer have a use for this one. Comes with standard corded power supply. Feel free to contact with any questions. Free pick-up or local delivery in San Antonio, TX

For sale here is the fabulous and lauded Woo Audio WA7 Fireflies (2nd Gen) headphone amp with both the WA7TP (tube power supply) and the linear power supply. All gear is original from Woo Audio directly and in pristine condition. The amp and power supply and tubes have ~200hrs on them and sound fabulous. This headphone amp drives anything and is spectacular with both my planar magnetics (Audeze & Mr Speakers) and my dynamics (AKG & Sennheiser). Ive even used the Sabre-based DAC alone to drive a separate tube power amp for speakers... excellent. The headphones pictured are NOT included with this offer for sale; any audio source players pictured are NOT included in this sale. The only reason this system is for sale is that I am cross-grading to a multi-bit DAC and dont have another spot for it ~ it is great (see the thousands of five start reviews and awards)... Woo Audio still sells this for $1600, despite a 3rd gen having already been released, probably because of tube power. Even used, this generation in this configuration (w/ 7TP, ESS Sabre DAC, & modern USB) is hard to come by. Heres a chance to own the kit for a great price. Some features & attributes include: Multi award winning DAC/AMP with great reviews and owner comments All-tube design (not hybrid) ~ pure valves Class-A, single-ended triode (SET), transformer-coupled power delivering one watt6C45 x2 driver/power tubes, 12AU7 x2 rectifier tubes for WA7tp tube power supply ESS SABRE Reference DAC (ES9018K2M)XMOS CORE-AUDIO asynchronous USB DAC reveals dynamics and detailsDigital audio files played through XMOS CORE-AUDIO asynchronous clocking hi-res audio playback up to 24-bit/384kHzUSB controller is compatible with PC, Mac, Android and iOS devices.Selectable analog RCA input or output for D/A mode 1/4 (6.3mm) stereo headphone output, dedicated 1/8 (3.5mm) output for sensitive in-ear monitors2 channel RCA output for DAC out use or aux input use Included solid-state linear power supply is in a compact external unit (I used the included WA7TP tube power supply)Compatible with 8-600 Ohms headphones, user ~ selectable Hi/Lo impedance settingWA7tp (tube power supply) employs 12AU7 vacuum tubesTransformers are custom made by Woo AudioHigh clarity glass covers for tubes protection - stabilize with ultra-thin silicon feet Body of both WA7 and WA7TP are of anodized aluminum in black ~ no blemishes Sales to PayPal payers only.

First generation Woo Audio Fireflies WA7, used. I bought this directly from Woo Audio owner when I lived in Brooklyn in 2020 and has been used only by myself. Tubes work flawlessly. The transparent glass block on the top has no chips of breaks, only superficial fingerprint smudges. Used this headphone amp for a couple years until I ended up getting an amplifier with a built-in headphone amp, now I no longer have a use for this one. Comes with standard corded power supply.
