Woo Audio WA11 Topaz Portable DAC/Amp - Excellent - Verified by HiFiLoop
The Audiophile's Hook
The Woo Audio WA11 Topaz is a rare portable that behaves like a serious desktop amp: fully-balanced, battery-powered, and Class-A—built to drive demanding full-size headphones while staying quiet enough for sensitive IEMs. This unit is Excellent (98% new) and includes the full original set, giving you flagship-grade portability for less than new pricing.
Condition Report (The Truth)
Excellent / Well-Cared For: Very clean overall, lightly used, and handled with care. Minor signs of use may exist under close inspection.
- No obvious cosmetic defects observed.
Mandatory: The device has passed all functional tests.
Sonic Signature & Pairing
WA11 Topaz focuses on speed, control, and headroom—punchy macrodynamics, stable imaging, and a “black” background that helps detail pop without sounding sharp. If you want portable authority for planars and power-hungry headphones, this is the kind of rig that can replace a small desktop stack on the move.
To unleash the full potential of this device, we recommend pairing it with gear from our Headphones Collection.
