TRUMPET MC Phonostage
3
Description
The Trumpet MC is a world-class phonostage suitable for the most demanding of
audiophiles. This 3rd generation model maintains the superb sonic performance of the
original, while cleverly cutting costs via technological advancements. The circuit remains
fully balanced from input to output, including power supply. Equalization is split-passive
with no feedback employed anywhere, resulting in a neutral non-fatiguing sonic
presentation. Heaters are DC and a highly specialized internal low-noise boost converter
generates B+ and B- rails (after a 40-second delay). A novel differential JFET front-end
provides variable gain and loading capabilities needed for MC operation. With this
flexibility any cartridge can be used, even MM. Premium components are used
throughout, such as polypropylene capacitors and metal film resistors. The aluminum
chassis has a rugged powdercoat, and is designed to match the Tuba.
