Fideles Standard

Derived from the Latin, meaning faithful, yet agile and lively.

“The one-of-a-kind cartridge was designed to introduce top level design, sound and material quality to entry high-end budgets – the Fideles sets an all new standard for performance and value alike.”

Unusual in this price class, the Fideles features a precise CNC body, carved out of a solid block of advanced Titanium Timet 1100 for unparalleled energy transfer.

The Fideles produces a very dynamic, live-like, colourful and openly transparent sound while it performs solidly several steps above it’s price range. It features very high tractability and is very easy to align. The stylus tip is exactly in the same vertical line of the front plane of the cartridge’s body when in the groove with VTF to specs. It’s relatively low body mass allows perfect synergy with a very wide selection of low to medium-high mass tonearms.

The Fideles features a unique body shape with ‘island’ mounting threads for maximum contact pressure and internal damping for maximum energy transfer. The generator system is a double-magnet focused field, moving ferrum pipe. This principle gives healthy high output of 5.5mV. It’s titanium body further features 3 rows of threads to allow perfect overhang in any headshell/tonearm.
