I measured the Leema Acoustics Essentials phono preamplifier (serial number ES140704B) using my Audio Precision SYS2722 system (see www.ap.com, and the January 2008 "As We See It"). As always with phono stages, I experimented with the grounding between the Essentials and the Audio Precision system to get the lowest level of noise.
The voltage gain at 1kHz was 35.7dB with the Leema set to MM (moving-magnet), and 61.2dB when set to MC (moving-coil). Both values are very close to their specifications, and the preamp preserved absolute polarity (ie, was non-…
