Who wins on what

Ranked by what users actually praise

Overall Impression

Sound character depends heavily on tubes and gain settings. Commenters note the WA22 is transformer-coupled, giving it current delivery closer to solid-state than a typical OTL tube amp, which lets it drive inefficient low-impedance headphones. Several say stock tubes sound thin and solid-state-like, requiring upgrades like Tung-Sol 5998 or Sophia 274B mesh rectifiers to get genuine tube warmth. Gain debates are unresolved, with some advocating always-low gain for pitch accuracy and others preferring high gain even on low-impedance cans.

Pairing matters a lot, especially with high-impedance dynamics. Owners report excellent results with ABYSS Diana v2, HD600/HD650, and high-impedance Beyerdynamic headphones, describing the amp as phenomenal and versatile. Planar magnetic headphones reportedly sound comparatively lazy or bloomy through tube amps like this one. Several commenters asked about DAC pairing and whether it outperforms other Woo models or competitors like Luxman and Feliks Audio, suggesting strong interest in system-matching advice.

Price growth and missing details frustrate some buyers despite love from owners. Multiple commenters mention the price climbing toward $2000-2500, with some saying that money could buy a full integrated tube amp instead, and one noting it has doubled in price in Australia. Others criticize Woo Audio for not publishing basic output/input impedance specs, making informed buying harder. A minor gripe is the lack of a dust cover. Despite this, several owners say they regret selling theirs or call it one of their favorite amps.
