A Welcome Reboot

The original Prestige debuted one of the best utilizations of the electrostatic (EST) driver in the IEM market. With a sustained EST output from 10kHz until 20kHz, the Prestige demonstrated the full potential of the EST driver and the treble extension that it could achieve in the IEM format. However, the high ultra-treble output could strain some listeners.

For this reason, Thieaudio has modified the EST drivers used in the Prestige LTD to achieve a more pleasant listening experience. The Prestige LTD features the same treble-extension capacity as the original, with near constant output from 10kHz to 20kHz. However, the high peaks at 12kHz and 15kHz have been eliminated by smoothing out the extension.

Simply put, the Prestige LTD features a more balanced sound signature with tightened bass, clean upper mids, and a natural treble curvature, providing a listener-friendly experience without compromising technical capabilities.

9 Drivers, 3 Driver Types, 5-Way Crossover

Like the original Prestige, the Prestige LTD features the same extensive and comprehensive engineering strategy. 4 Sonion electrostatic drivers + 2 Knowles mid-treble balanced armatures + 2 Sonion low-mid balanced armatures + 10mm dynamic subwoofer are used per each side of the Prestige LTD. With an over-engineered 5-way crossover tuning strategy, the Prestige provides extreme layering and texture across the whole spectrum.

More Balanced Sound Signature

The Prestige LTD has a slightly modified tonal signature compared to its predecessor. With modifications to the 10mm Dynamic Driver, the bass shelf has been tightened to 200Hz. With a better controlled and tighter bass, the sub-bass impact is more focused and faster, helping create a cleaner overall sound signature. THIEAUDIO’s classic flat mids are retained in the Prestige LTD to achieve a professional studio-monitor accurate sound. Besides the smoothing of the ultra-treble, the upper mids and trebles have also been cleaned up to provide a more natural treble curvature. In sum, the Prestige LTD provides a more listener-friendly sound signature that is easier to enjoy, while staying true to its professional technical capacities.
