Up for sale is a Woo Audio WA8 Eclipse Tube Headphone Amplifier. This an amazing amp with a DAC included and is portable, running off the purity of battery power. It is in mint condition and comes with all the original accessories. I only ever used it in my house. I bought this unit new in July and have only used the amp as instructed in the manual - with battery power. 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!
