The Leach is a no-brainer that works. You can build better today with some effort but not much quieter.
Pre-Pre-Amp Building Leach design or Op-
A contributor to Audiogon suggested to me the Marshal Leach circuit for a moving coil pre-preamp which looks simple but elegant. I on the other hand was considering a low noise op-amp type design. Has anyone out there built the Leach design and would they care to comment. Has anyone used op-amps for such an application and would they care to comment?
This is a stop gap project as I am building a Daniel pre-amp which will handle MC cartridges, but completion is probably a year away and I would like to use the MC cartridge I acquired.
