HeadAmp Blue Hawaii Special Edition Electrostatic Headphone Amplifier
Our Take
No other amplifier on the market can provide electrostatic headphones with the accuracy, drive, and control of the Blue Hawaii SE. When paired with the Dan Clark Audio Corina, Stax SR-X9000 or Audeze CRBN, the headphones come alive with detail, transparency, and bass control unheard on with lesser amplifiers. With more power on tap than any other commercial electrostatic headphone amplifier, the Blue Hawaii SE can find a home in any audio system, and its clean, modern lines will always draw admiration.
The Blue Hawaii SE is the flagship HeadAmp product, and based on over a decade's experience building electrostatic headphone amplifiers, it is designed not only to power the toughest headphone loads on the market, but to do so for a lifetime. No expense was spared in the design and build of the Blue Hawaii SE, and every amplifier is tested extensively throughout the build process, as well as before, and after an extensive burn-in process to ensure the best possible performance.
The Blue Hawaii SE is available with two volume control options. The first is a 24-level step attenuator, providing perfect channel matching at each possible volume level. For those who desire infinitely granular volume control, we offer the ALPS RK50 potentiometer, the highest-grade part of its' kind, which gives you the freedom to set the volume just-so, without compromising sound quality.
There are also two options for feet on the Blue Hawaii SE. The precisely machined and finished aluminum spike feet match the accent color of the front panels ad tube rings, and are compatible with various audiophile isolation platforms. We also include a set of rubber feet that offer different isolation characteristics, and a non-mar option for delicate surfaces.

HeadAmp Blue Hawaii Special Edition — natural, transparent electrostatic authority
HeadAmp’s Blue Hawaii Special Edition Electrostatic Headphone Amplifier delivers a remarkable synthesis of transparency, musical weight, and dynamic authority that makes electrostatics sing. As reviewed by K. E. Heartsong / AUDIOKEY REVIEWS, the BHSE pairs tube warmth (four Mullard EL34s) with electrostatic speed to render a natural, transparent musicality—taut, propulsive bass, richly textured midrange, and crystal yet controlled treble. Imaging is expansive, with a volumetric soundstage and precise layering, while the reviewer highlights exceptional dynamics and a black-quiet noise floor. Built in a modern-retro chassis with an external power supply and dual electrostatic outputs, it’s practical and well finished. Ideal for electrostatic headphone enthusiasts seeking near-TOTL performance without paying significantly more, the BHSE is a compelling endgame amp for those prioritizing musical realism and fine detail.
Pros
- Natural, highly transparent musicality with excellent tone, timbre and texture that brings performances to life.
- Outstanding dynamics and transient authority with taut, propulsive bass and strong low-frequency impact.
- Expansive, well-layered soundstage and precise imaging that reveal depth, width and player placement.
- Robust build and thoughtful functionality—Modern‑Retro chassis, external power supply, dual five‑pin electrostatic outputs and clear front/back layout.
&
Cons
- Only a single balanced (XLR) input is offered; reviewer notes a second XLR would be desirable for multi‑source setups.
- While superb overall, a much pricier rival (Viva Egoista STX) is reported to offer slightly greater air and high‑frequency refinement.
Sound Quality
93/100
Dynamics are a clear strength: the reviewer describes 'unparalleled dynamics, transparency, resolution, deep bass assaults,' and says the unit 'ticks off all boxes' including startling dynamic shifts and bass potency. Transient response and punch are repeatedly affirmed through listening reports, including taut, propulsive bass performance. The praise is strong enough to place dynamics at a top-tier desktop level.
Noise Floor
90/100
Reviewer specifically cites a 'black-quiet background' that enhances anticipation and detail—language that implies an exceptionally low noise floor suitable for revealing recordings. The description supports suitability with sensitive electrostatic cans and indicates very quiet operation in typical listening environments. No reviewer complaints about hiss or background noise are present.
Headphone Compatibility
82/100
The unit is purpose-built for electrostatic headphones (1600V p-p output, dual five-prong electrostatic outputs) and reviewers evaluate it in that context, where it excels. Because it is specialized for electrostatics it is not a generalist amp for dynamics/planars; reviewers did not report testing across a broad range of dynamic/planar models, so flexibility is limited compared with multi-topology amps. Given excellent electrostatic performance but constrained broader compatibility, a strong but not reference score is appropriate.
Build Quality
92/100
Reviewer calls the construction 'beautifully constructed' with a 'clean, well executed' industrial design (Modern-Retro), noting both aesthetics and functionality. The physical presentation and implied component/craft quality are consistently positive, including a separate outboard power supply and solid ergonomics. No build or reliability concerns are raised.
Features Connectivity
86/100
Feature set exceeds the minimal amp baseline: dual electrostatic headphone outputs (two listeners), two XLR inputs, two RCA inputs, XLR and RCA loop outputs, and external power supply connection—useful for electrostatic workflows. There is no built-in DAC, streaming, or balanced headphone jacks for dynamics/planars, so the feature set is strong for its electrostatic niche but not comprehensive for a modern all-in-one desktop streamer/DAC/amp. Score reflects baseline plus multiple inputs and loop outputs (+ extras).
Value for Money
90/100
Reviewer positions the BHSE as delivering performance close to a far more expensive alternative (Viva Audio Egoista STX) and explicitly says that those unwilling to pay the higher price 'will not, for a moment, disappoint.' Given that praise relative to pricier peers and the stated $7,995 outfitted price, reviewers frame the BHSE as a justified premium in its class.
