MASTERLINE 7
The HSE Phono Preamp Masterline 7 (ML-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 utilized.
12 HSE discrete Class A Gain-stage and 2 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 aluminum block,
protecting the electronics with a 20mm strong
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 reach the ultimate uncompromising sound, only
the industries best components, from ELMA,
Goldpoint, NKK, Panasonic, WIMA, Neutrik, Schurter,
and HSE in-house wound coils are being used.
The audio signal passes our proprietary HSE silver-
teflon wiring and the oversized toroidal transformer
featuring static and magnetic shielding.
The Impedance selector is optimized for the industry-
leading Benz, Lyra, XYZ, Ortophon pickups. The unique
extensive gain range of the Masterline 7 equally
supports all alternative pickups of choice, no matter
how minimal their output levels are.
