We heard lots of electrostatic head amps but keep tossing about a single tube amplifier that could get the most tonal richness and depth out of Stax's 009/007 as well as high-end dynamic headphones such as Focal's Utopia, Kennerton's Odin; and other electrostatic ear-speakers with various bias voltage. After months of prototyping, we have finally reached to the version that fulfills those expectations, called DT-HWT.
It delivers a feeling of musical harmony that we never got close to before. The mid-range is gloriously rich, with more timbre on vocals. The bass is much fuller with far more weight. The soundstage is also expansive and the separation is much clearer.
With a separated and dedicated power supply unit, the noise floor dropped noticeably that you become very aware of the singer's breathing and physicality.
The highly reserved power supply circuit is constructed with choke coils and large capacitor group; achieving high headroom and wide bandwidth sound possible.

Two clips below demonstrate the DT-HWT performs as a preamplifier out to the Rotel RB-1552 mk1 power amp, driving a pair of DYN Contour 30 floor-standing loudspeakers, which gave just a glimpse of its natural and purest bliss of the sweetest sound signature. Music was flowing through your body with a level details that second to none.
