Woo Audio WA23chat_bubble_outlineFrom real comments

Listeners consistently call the WA23 Luna one of the best-sounding headphone amps they've heard. Multiple commenters who auditioned the WA23 at CanJam or owned it describe it as a favorite amp, only bested by ultra-exotic setups like Susvara/Mass-Kobo or the HE-1. Owners praise its ability to drive hard-to-amp headphones like Susvara and LCD-series planars while also pairing beautifully with Sennheiser HD650, scaling amplification to suit each headphone's needs. One listener called its clarity and refinement unmanufactured and 'very natural, and real,' distinguishing it from competitors.

The amp's striking design and separate power supplies impress commenters, but ergonomics see some criticism. Commenters repeatedly call it gorgeous and among the best-looking tube amps on the market, citing its refreshing design and standout build presence. Separate PSUs are noted as a meaningful factor in sound quality by at least one owner familiar with similar designs. However, one user was disappointed by low-key, hard-to-see markings on the knobs and the absence of a 4.4mm jack, wishing for better visual cues like color-changing LEDs.

Its roughly $9000 price tag sparks debate about value, component cost, and a reported buzz. Several commenters question how such pricing is justified given the actual cost of electronic components, with one self-described 50-year electronics engineer skeptical of the markup. Another commenter bluntly states that at this price point there should be no audible buzz, while others speculate the buzz stems from shorting-plug placement rather than a design flaw. Despite the criticism, some justify the cost by pointing to the 'magic' of no-compromise high-end audio design.
