There's a conceptual abstraction of the ideal amplifier discussed among electronic designers: the famously touted "piece of wire with gain".
Now, here we literally have it: The Consolidated Audio "Monster Can" MC step-up transformer is exactly that! Choosing the lowest loss and highest permeability core materials and combining these with an optimized winding technique to minimize and balance the parasitic elements inherent in any transformer design enables us to provide passive voltage amplification with just a piece of wire! Utilizing the drive capability of low impedance MC phono cartridges we thus can eliminate the active "pre-pre" or high-gain MC phono stage with their often noisy performance and tendency to mask low level detail.

Core Material
Consolidated Audio "Monster Can" MC StepUp Transformers are available based on two different soft magnetic core materials:

Hi-Nickel (80% Nickel aka MuMetal)

The "classic" material for high quality, low level audio signal transformers. Musical and coherent, bodily presentation.

Nano Crystalline

A "state of the art" core material for wide bandwidth, low loss audio signal transformers. Detailed and spacious. Airy and elegant, effortless presentation.

Turns Ratio
The step-up transformer turns ratio determines the passive voltage amplification factor together with the cartridge loading by the phono stage input impedance. One approach to frontend optimization therefore is the matching of nominal cartridge output voltage to the nominal input voltage of an MM phono stage (usually 5 mV). A second approach gives priority to cartridge loading by the transformed input impedance of the MM phono stage (usually a 47 k resistor in parallel to input + cable capacitance).

Low Ratio (1:10 / 20 dB)

By using a step-up transformer with a 1:10 turns ratio a cartridge with a characteristic output voltage of 0.5 mV @ 5 cm/s would meet the standard input voltage requirements of an MM phono stage. Resistive loading of such phono pickup would be 470 ohms since the SUT transformes impedances by the square of its turns ratio.

Medium Ratio (1:15 / 23.5 dB)

For cartridges of ca. 0.35 mV @ 5 cm/s. Cartridge loading by the transformed charactersistic MM phono stage input resistance is approx. 210 ohms.

High Ratio (1:20 / 26 dB)

For cartridges of ca. 0.25 mV @ 5 cm/s. Cartridge loading approx. 120 ohms.
