Swiss-Built CH Precision Phono Preamp Includes Oscilloscope

Michael Fremer  |  May 23, 2015

The CH Precision phono preamplifier includes three inputs, two of which are current mode MC and one of which has a conventional voltage gain-based architecture that be used in either MM or MC mode.

The CH has both single-ended RCA and balanced XLR inputs. The oscilloscope aids in adjusting loading to damp the cartridge resonant frequency. Thus you can achieve close to flat frequency response by avoiding either underdamping or overdamping. Price is 26,000 Swiss Francs.

...a disc of test tones for use, in conjunction with the 'scope display, when trying to adjust the load settings (for flattest frequency response)?
