Hand crafted in Switzerland by audio engineer Robert Huber, the HSE Phono Preamp Masterline 7 represents the pinnacle of audio engineering, shown here on its antivibration support stand. Engineered for a life expectancy of at least 30 years, only the highest quality handmade Swiss components are utilised. Twelve HSE discrete Class A gain-stage and two Zero-ohm Class A ultra-low noise head-amps guarantee best possible audio performance.
For uncompromising EMC shielding, the case of the ML-7 is milled from a solid aluminium block, protecting the electronics with a 20mm housing. Gold plated dials allow the adjustments of the Dual Mono Preamp for each channel individually. Each device passes a 2-week continuous hardening and maturing test to reach the finest sound quality. All electronic components are hand-selected and matched up to 0.1% maximum variance.
To achieve uncompromising sound, only the industry’s best components, from ELMA, Goldpoint, NKK, Panasonic, WIMA, Neutrik, Schurter, and HSE in-house wound coils are used. The audio signal passes through HSE’s proprietary Silverteflon wiring and the oversized toroidal transformer featuring static and magnetic shielding. The Impedance selector is optimised for industry leading cartridges and one of the greatest features of this phono preamplifier is that the extensive gain range eliminates the need for a step up transformer and can support all cartridges, no matter how low their output levels are.
The HSE’s quality and engineering is such that the noise floor is virtually non-existent, allowing the musical nuances & micro-detail to emerge and flow. One of the very best!
