Rothwell MCX Moving Coil Step Up Transformer

This step-up transformer uses the same high quality cores as used in the MCL, again supplied by Lundahl of Sweden, but features a lower turns ratio than the MCL to accommodate cartridges with higher outputs.

It features very wide bandwidth, low distortion and carefully designed primary and secondary loading networks to optimise the performance and give beautifully reproduced transients, free from ringing. 

The core materials and winding techniques employed in the manufacture are unsurpassed and feature multiple primary and secondary windings configured to cancel hum pickup from external sources as well as minimise inter-winding capacitance and maximise bandwidth. 

The step-up ratio of 1:10 makes the MCX is compatible with a large selection of moving coil cartridges available today from makers such as Benz Micro, Clearaudio, Lyra, Koetsu, Ortofon, Audio Technica etc., but is particularly suited to cartridges with higher than average outputs, those in the range 0.6mV to 0.9mV.

Perfect partner for the Rialto phono amp
14 April 2021  | 

When I paired the MCX with Rialto, using River interconnects, music I have been listening to for 25 years made my hair stand on end and want to jump around as if I was at a gig. The music became fuller bodied, more detailed and the individual instruments and vocals can be heard in, what I have heard others describe, as 3D. Absolutely thrilling to listen to. Well-built and faultless components with first class customer service. Highly recommended.
