...preamp with superb moving coil
capability
This is a real task to find. Even when you will get a lot of
recommendations, this kind of knowledge is not available anymore.
Some have an internal Phonostage, but they are maybe "ok" but f-a-r
away from superb. Even in the 90's there was only one with a
"superb" Phonostage, that was a Jeff Rowland Consonance. In
the last 10 years I only found the Klyne 7 which was able to do a superior
job with internal MC Phono.
Why don't you go for a cartridge with a higher output? It is no secret that
CAT preamps work much better with those than 0.3mV or below.
Their internal gain is simply not made for that. Benz has a wide choice
with various outputs ...
