The result? A preamplifier capable of OUTSTANDING clarity and information retrieval.
When driving the ADAMANTINE preamplifier, the electrodynamic motor in the cartridge is converted to being displacement-sensitive (like a strain-gauge or optical cartridge) by sensing the short-circuit output-current from the cartridge as explained in this article or this video.
The resulting signal recovered from the groove only requires modest equalisation instead of the 100:1 ratio required for RIAA resulting in unparalleled audio transparency.
From stylus to sound, with only gain in between
