HeadAmp Blue Hawaii Special Edition Electrostatic Headphone Amplifier

Audiokey Reviews praises the BHSE's transparency, resolution, detail, air and beautifully rendered decay, describing a highly palpable sense of performers. The Absolute Sound found it subtly revealing and excellent at conveying both fine inner detail and the musical whole, though it judged a competing Woo marginally more microscopically revealing.

Reviewers repeatedly call the presentation natural, with convincing tone, timbre, texture and a sense of gravitas across the spectrum. The Absolute Sound hears a fundamentally neutral balance with a touch of warmth, while also crediting it with smoothness and freedom from stridency or excessive sibilance.

Dynamics are a major strength: Audiokey Reviews reports startling shifts, deep bass impact and an unparalleled sense of drive in its reference system. The Absolute Sound calls its dynamic flow unequalled in its experience and notes excellent guitar dynamics alongside deeply defined bass.

Audiokey Reviews specifically describes finely detailed ambience and decay emerging from a black-quiet background. The other review offers little direct discussion of hiss or hum, so there is limited evidence concerning performance with exceptionally sensitive electrostatic headphones.

This is a purpose-built electrostatic amplifier with substantial 1600V peak-to-peak output capability and two five-pin electrostatic headphone sockets. Reviewers report exceptional results with Stax SR-009 headphones, including bass control, smoothness and dynamics; it is not designed for conventional dynamic, planar or IEM use.

The Absolute Sound calls the fit and finish simply superb, praising the handcrafted execution, metalwork, engraving and precise fit of parts. Audiokey Reviews likewise finds it beautifully constructed, cleanly executed and functional as well as visually distinctive.

The BHSE provides two five-pin electrostatic outputs, balanced XLR input, two RCA inputs, and both XLR and RCA loop outputs. Its dedicated outboard power supply and optional Alps RK50 volume control support a serious desktop installation, though there is no onboard DAC, remote, digital input or broad headphone-format support.

At the reviewed $7,995 configuration, Audiokey Reviews found that only a Viva Egoista STX costing more than twice as much exceeded its performance, and said listeners unwilling to pay that premium would not be disappointed. That comparison makes the BHSE look particularly compelling within the high-end electrostatic category, despite its substantial purchase price.
