you know I have tested many, many MC StepUp transformers. Finally I ended up with Kondo (the real old ones), Silvercore (Wahnfried) and Consolidated Audio.

When Michael Ulbrich from Consolidated Audio in Berlin visited me we looked and listened also to another innovation of his SUTs, the Multi Ratio MC Step Up version. It means you may be able to play with a flexible ratio – adapt SUT to MC cartridges with a wide range of output voltages and also use flexible primary inductance – match SUT with a wide range of MC cart internal impedances.

Ratio/ Inductance Selection
In this dual version (a mono version is available too) a selection is accomplished by four jumpers with gold plated sockets and pins. Starting from a middle ratio N the SUT is configurable for ratios 1:10, 1:20 and 1:40. Two levels of primary inductance are available : High (H) with ratios 1:10 and 1:20 and Low (L) with ratios 1:20 and 1:40,
Hence a single Multi Ratio SUT is equivalent to four standard SUTs each with only a single ratio/inductance configuration. Please see the images above, where the four different jumper configurations are shown. The lower image displays a prototype with the identical technology.
